microINJECTOR™ All-Digital Positive Displacement System

  MINJ-PD:  $2,702.70 - In Stock

For applications that require a specific volume to be delivered or aspirated in the nanoliter / microliter / milliliter range, at a defined rate, Tritech Research offers the motorized MINJ-PD Digital Positive Displacement microINJECTOR™. Unlike most other microinjection controllers, this system does not require attachment to a gas cylinder, pump, or compressed air line. It works like an electronic syringe pump and is completely self-contained.

With the injection volume and speed set in advance, this motor-driven microinjector injects very small volumes of liquid with precision control via a foot switch, leaving both hands free for micromanipulation and focusing the microscope. In addition to fixed injection volumes, there is also a Manual Mode that allows the user to inject without knowing the volume in advance. In Manual Mode, the MINJ-PD displays a tally of the amount injected.

The MINJ-PD was originally designed for stem cell injection into blastocysts, and is now used for stem cell injections into human spinal cords. We're proud to say that (while For Research Use Only) it is currently the only FDA-listed device for injecting neural cells into the spinal cords of ALS patients and people with spinal cord injuries by the scientists at Neuralstem, Inc. and their collaborators worldwide. This injector is also used for micro-perfusion and delivery of drugs, neurotransmitters, and vectors to brain, retina, and cultured cells in neurobiology, for injecting insects in pathogen studies, and for many other applications. In 2017, we revised the hardware and firmware to support smoother, more precise delivery, easier loading of sterile syringes, and to add a Pressure Mode.

In addition to the original Positive-Displacement Mode, where the MINJ-PD syringe, tubing, etc. are filled with liquid for hydraulic action, a new Pressure Mode allows the MINJ-PD to be partially or completely air-filled for pneumatic injection control without the need of an external pressure source! In this mode, when you push the foot pedal, the syringe advances to create a positive pressure that makes things flow from the needle; when you release the pedal, the syringe returns to its neutral position to stop the injection flow. Inversely, the unit can be used to aspirate.

There are distinct advantages to Positive-Displacement Mode vs. Pressure Mode. In Positive-Displacement Mode, it is possible to set a specific delivery volume and delivery rate. Unfortunately, this is only practical for volumes over 1 µL because thermal expansion, elasticity, etc., become significant compared with volumes smaller than this. Pressure Mode can deliver volumes arbitrarily small, for example in the picoliter range, but the actual volume will be determined by the pressure, time, needle hole size, and viscosity of the the substance.

For stem cell injection, a special built-in Agitation Mode helps to prevent cells from clumping and settling on the wall of the needle between injections.

The MINJ-PD employs the same user-friendly microprocessor interface as the MINJ-D. It digitally synthesizes injecting / aspirating volume and speed, as well as agitating volume and speed, reproducibly. Using a simple "Menu" button, and Plus and Minus buttons, anyone can set the volumes and the speeds in seconds. Here are the key features and specifications of the Positive Displacement Digital microINJECTOR:
  • Most compact and robust on the market
  • 6" x 7" x 3" and weighs under 2 lbs.
  • (15cm x 17cm x 7cm and weighs under 1 kg)

The output of the microINJECTOR needs to be coupled to something. For example, if you're using glass microcapillary needles, our MINJ-4 microINJECTOR™ Brass Straight-Arm Needle Holder will do the job cost-effectively. Please note that, for use with the MINJ-PD, a special version of all MINJ-4 variations will be supplied that uses a gas-tight swage fitting and terminates in a Luer/Slip fitting to attach conveniently to the MINJ-PD's syringe. The pictures below show the MINJ-4 variations with a quick-connect fitting that looks a bit different than what you will receive.

High-speed Pneumatic microINJECTOR™

  MINJ-FLY:  $3,891.89 - In Stock
Image for  coming soon!
For demanding applications, like injecting drugs and pathogens into adult Drosophila, that require a full-featured and fast microinjection system, Tritech Research offers the MINJ-FLY High-speed Pneumatic microINJECTOR™. In basic microinjection, a hollow needle with a microscopic tip is filled with a liquid, poked into a target, and then temporarily pressurized so as to inject some of the liquid into the target. The variables that determine the amount injected are pressure, time, viscosity of the liquid, and diameter of the needle opening. A simple, practical system for accomplishing this is our MINJ-1 microINJECTOR™ (standard model) or our MINJ-D All-Digital Multi-Pressure microINJECTOR™;. While the MINJ-1, and its line of accessories, help many scientists breeze through their microinjections, some experiments and procedures require a higher level of sophistication, accuracy, and reproducibility which can be better accomplished with the MINJ-D. But some experiments require a faster response times which can be as low as 10 ms with our MINJ-FLY.
The MINJ-FLY employs a user-friendly microprocessor to digitally synthesize injection durations reproducibly. Using a simple "Menu" button, and Up and Down buttons, anyone can set the pressures and the injection duration in seconds. It's so intuitive, you won't have to read the directions! You can as well change the mode from injection mode to fill mode and trigger the respective operation with the foot pedal. Here are the key features and specifications of the High-speed Pneumatic microINJECTOR™:
  • Most compact on the market
    6" x 7" x 3" and weighs under 2 lbs.
    (15cm x 17cm x 7cm and weighs under 1 kg)
  • Very fast response time between pressures (~10 milliseconds)
  • Simple 3-button control
  • Digital display with backlight for easy reading
  • Microprocessor accuracy
  • Foot pedal included for hands-free injection control
  • Pressure range: 0 - 80 psi
  • Programmable Injection Duration: 25ms - 999.0 seconds
  • Electronic Vacuum Generator to front-fill needles by aspiration
  • Injection Data-logging Port for optional computer interface
  • Injection Control Port for optional computer control

The MINJ-FLY can be attached directly to a laboratory compressed air jet or attached to a compressed Nitrogen cylinder using a pressure regulator such as our TREG-N2.  The system is designed to use a minimum of gas, so even a small cylinder may last for months or years. When ordering, please let us know if you intend to attach your injector to a compressed gas source or an in-house air jet, so that we can provide you with the proper fittings for attachment.

For demanding applications that require a full-featured microinjection system, Tritech Research offers the MINJ-D All-Digital Multi-Pressure microINJECTOR™.

A simple, practical system for accomplishing this is our MINJ-1 microINJECTOR™ (standard model). While the MINJ-1, and its line of accessories, help many scientists breeze through their microinjections, some experiments and procedures require a higher level of sophistication, accuracy, and reproducibility. In basic microinjection, the needle is either at a user-set pressure when injecting, or at atmospheric pressure when not injecting. In some cases, backflow of cytoplasm or medium into the needle can be problematic. For these cases, a lower "holding pressure" that is lower than the injecting pressure, but higher than atmospheric pressure is useful between injections. A holding pressure can also reduce needle clogging. No matter how careful a person is, needles occasionally do clog. For these cases, a short blast of a "clearing pressure," higher than the normal injection pressure, is useful to unclog the needles. The MINJ-D employs a user-friendly microprocessor to digitally synthesize injecting, holding and clearing pressures, as well as injection durations reproducibly. Using a simple "Menu" button, and Up and Down buttons, anyone can set the pressures and the injection duration in seconds. It's so intuitive, you won't have to read the directions!

FAQ's

Q: What is the pressure resolution of the microINJECTOR™?
A: The MINJ-D is capable of pressure control in increments of 1 psi or 1 kPa (6.9 kPa = 1 psi), depending on which unit mode you choose... So you get almost 7 times more resolution in kPa mode!

Q: How much input pressure should be supplied to the MINJ-D via my regulator when using a lab air jet or nitrogen tank as a pressure source?
A: First, never exceed 80 psi (550 kPa), or you may damage the unit or create an unsafe situation!

For the best control, you should set the regulator just a little higher than the highest pressure that you need to deliver. You could start with 50 psi (345 kPa) input and then use the menus to find the best injection pressure (and possibly a clearing pressure that is higher than the normal injection pressure). If you find, for example, that your useful pressures are all under 20 psi (140 kPa), and that the unit is overshooting or not hitting/maintaining the pressures as consistently as you would like, then you can lower the input pressure to 25 psi (175 kPa), and it will be more stable at lower pressures.

Q: Can I still use the MINJ-D with my laboratory compressed air jet or compressor if it delivers greater than 80 psi (550 kPa)?
A: The MINJ-D requires input pressure between 10 psi (70 kPa) and 80 psi (550 kPa); it must be at least the pressure you need to deliver, but not more than 80 psi. If your lab air jet or compressor might ever deliver pressure above 80 psi, you can use a low-pressure regulator with quick-connects at the input and output ports to reduce and stabilize the input pressure. You can order these from us, so contact us to order the correct model. Please note that opening an air jet port only slightly or restricting the flow does not lower the pressure in a closed system, it only slows down how long it takes to get to the full pressure; a pressure regulator is needed to lower the pressure.

Q: How can I prevent material from flowing out through the tip of the needle even when the foot pedal is not depressed?
A: If material is flowing out of the needle between injection pulses, this indicates excessive Holding Pressure. You can either set the Holding Pressure to zero, or set it more precisely. If you are having trouble finding a Holding Pressure menu setting where nothing is coming out of the needle, and you are in PSI mode, you might want to start by switching the unit to kPa mode by using the Units menu. This will increase the pressure resolution by nearly a factor of 7. If that still doesn't achieve the holding pressure you'd like, then select the Holding Pressure where it is slightly too high (some solution is still coming out of the needle) then turn the vacuum control knob (on the right hand side of MINJ-D) slowly counter-clockwise (from its original closed and fully-clockwise position) until no more solution is flowing out of your needle tip. The vacuum control knob adjusts the system from injecting-mode (all the way clockwise) to vacuum-mode (all the way counter-clockwise). By turning the knob slightly counter-clockwise, you are reducing the pressure slowly until you find the balanced pressure where there is no material flowing out of your needle tip. With appropriate Holding Pressure, there should be minimal flow out of the needle between injections.

Q: I am trying to inject zebrafish/xenopus eggs and not getting good control. What settings or procedures should I use?
A: Make the needle tip opening as small as possible. Having a smaller needle tip will increase your accuracy when injecting with the MINJ-D because it will let you use higher pressures to get the desired volume injected. We recommend using the procedure of etching the needle tip in HF acid to open the needle tip so that it is sharper and creates a smaller opening than just breaking it off with an exacto knife or tweezers. We have a protocol for this in the FAQ section of our MINJ-PP product page.

By injecting some dye into a petri dish of water, and you can experiment with setting the pressure to make sure that the Holding and Injecting pressures are set appropriately so that there is minimal backflow of water or outflow of dye with your needle, without wasting any of your actual sample. You can also switch the unit to kPA mode instead of psi mode, and you will get nearly 7 times more precision. You can also lower input pressure to a bit higher than the actual pressure at which you are injecting. This way, the MINJ-D will be able to regulate the pressure more precisely. For example, if your injecting pressure is at 2 psi (14 kPa) but your input/source is at 80 psi (550 kPa), each time you press the foot pedal, your injection may overshoot because the inrushing input pressure is so much higher than your injection pressure; however, if your injecting pressure is reduced to 5 psi (35 kPa), there will be less overshoot.

Q: How do I connect the tubing to my Nitrogen regulator?
A: If you purchased the TREG-N2 N2 regulator from Tritech Research, it should have a brightly colored "quick-connect" fitting in its output, and the MINJ-D tubing should lock right into it. The way that the quick-connect works is: to lock in the tube, you insert the tube in as far as it will go (you will feel resistance and overcome it) and when you slowly try to pull out the tube, you will then feel it lock into place; to remove the tube, hold in the brightly colored ring of the quick-connect fitting while pulling out the tube.

Q: What procedure would you recommend to stop everything between injections to avoid turning on and off the system multiple times?
A: Turning the system off does not vent the holding pressure. Instead, it will vent when you turn it back on. In between injections, to cancel an ongoing injection or deactivate the Holding Pressure, we recommend using the Minus Button (-), which activates the Abort function. It will stop the current pulse, if any, and it will also vent the Holding Pressure.

Q: How can I reset the system to factory settings?
A: To reset the device to factory settings:
1) make sure power is turned off
2) hold down the plus (+) button
3) while continuing to hold down the (+) button, turn on power to the device
4) after text appears on the display, release the (+) button

Q: How can I load the specimen manually from the back?
A: In most microinjection applications, the total volume for all the injections is less than 1 microliter, and the tip is too small to suck up anything meaningful, so you can preload the needle from the back before you put it in the needle holder. This can either be done by capillary action, if the amount needed is well less than 1 microliter and the pipets have an internal glass filament, or they can be filled from the back by drawing a glass tube very finely with a flame or by using commercially available loading pipets (each of which are fine enough to fit inside the OD of the capillary tube).

Q: Is there a maximum vacuum pressure that the MINJ-D is able to apply?
A: The theoretical maximum vacuum for the unit, if you have the injecting pressure set to 60 psi with an input pressure of 80 psi (the maximum allowable) and the vacuum control valve wide open and a needle in the needle holder is: -86kPa = -12.5 psi = -.85 atm. Which isn't bad considering a perfect vacuum is 1 atm. Under more normal settings and realistically, it would be about half of that.

Q: For Xenopus egg injections,
- What is the ideal injection pressure?
- What is the ideal holding pressure?
- What is the ideal clearing pressure?
- What is the ideal injection interval?
A: The answer to all of the ideal settings above will be highly dependent on the needle tip opening. We suggest an extremely fine tip in the 1 micron range. In that case, you might inject at 10 psi for 1 second and have a holding pressure of maybe 2 psi and a clearing pressure of 30 psi.
However, some labs use much more open needles, and the pressures need to be much lower. We recommend the acid etching technique described on our MINJ-PP page in the FAQ section at the bottom to get very sharp needles.
The vacuum pressure control is the very small gray knob on the right side of the MINJ-D box. For normal injection, it should be screwed in all the way (clockwise). For a strong vacuum, it should be unscrewed until you hear maximum flow. For fine control of the holding pressure, it should be unscrewed minimally to prevent flow out of the needle tip when a low holding pressure is set.

Q: Is it possible to deliver brief injections (e.g. 100us) every 1s by keeping the foot pedal pressed?
A: The short answer is no. The MINJ-D has a minimum injection time of 100ms (0.1 secs). Even if the valve could switch at speeds in the microsecond range (its minimum switching time is about 10ms, as achieved in our MINJ-FLY) I don't think that it would be meaningful because it would take much longer than that for the air in the tubing and needle holder and pipette to pressurize and depressurize.
We have a version of the MINJ-D with a computer interface that would allow it to give repeated pulses, for example every second. The important variable is to get your needle tips to the right opening size such that 100nl comes out at a pressure setting of several psi in less than 0.5 secs. Then you will have good control.

microINJECTOR™ System

  MINJ-1:  $643.24 - Ships in 1-5 days
Image for microINJECTOR(TM) System coming soon!
Tritech Research has designed a microinjection system that lets you control with exacting precision both the pressure and the duration of the microinjection pulse. And, it's available at a fraction of the cost of competing systems.

Our microINJECTOR™ System uses a precision pressure regulator and a high-speed electronic solenoid switching valve, yet it is amazingly robust and simple to operate. It allows you to start and stop injection within a fraction of a second and control the quantity and flow of material into your target with precision. Our electronic foot control is designed to keep your hands free so you can concentrate on the manipulation of your needle and target.

The microINJECTOR comes preassembled, ready to use. You need only to attach the system to a compressed gas tank (e.g. N2) or in-house pressurized air line at one end and your needle at the other. You set the desired pressure and the system delivers pulses of pressure to your needle. In the base model, the duration of the injection pulse is controlled by how long you hold down the high-speed electronic foot pedal. With our easy-to-use, reliable equipment there is no "magic" required. Even a novice will be turning out transformants the first day.

The Single-Pressure MINJ-1, shown, switches between the injection pressure, during injection, and atmospheric pressure between injections. The Dual Pressure Option allows the user to apply a secondary, adjustable positive holding pressure to the needle between injections. This balance pressure is lower than the injection pressure but higher than the atmospheric pressure in the room. It can prevent backflow of media or cytoplasm into the needle, reducing sample dilution and needle clogging, respectively. Click HERE to see a photo of the Dual Pressure MINJ-1 or HERE to see the more compact low-input-pressure version of the Dual Pressure MINJ-1.

With our optional electronic MINJ-2 Pulse-Length Control Module (PCM) you can set injection times from ~0.1 to ~15 seconds. Each time the pedal is pressed, a constant volume is reproducibly injected. This option is crucial for quantitative experiments such as transient expression assays following microinjection of DNA, RNA, protein or other substances. For manual control, just set the time to maximum, and stop pushing the pedal early!

By controlling the pulse length and pressure independently, you can compensate for the flow characteristics of individual needles; you can determine if the needle is properly placed prior to any appreciable damage occurring to your target; and you can fill your target incrementally. High pressure settings with rapid on/off pulses aid in unclogging needles. The MINJ-2 is required for all orders to countries that use 220-240 volts, as the means of powering the MINJ-1.

As an added option to the microINJECTOR System you can hold your target with our state-of-the art MINJ-3 Holding Pipette Controller (HPC). The HPC allows you to pick-up and hold your target with vacuum suction and then release it with positive pressure. Our unique pneumatic foot pedal control allows a continuous range from vacuum through positive pressure depending on the position of the pedal. It is ideal for holding and manipulating targets such as embryos and oocytes. It is lso useful for injecting ES cells into Blastocysts. As any of our customers will attest, within a short time you will be proficiently getting transformants.

The output of the microINJECTOR needs to be coupled to something. For example, if you're using glass microcapillary needles, our MINJ-4 microINJECTOR™ Brass Straight-Arm Needle Holder will do the job cost-effectively.

FAQ's

Q: How do you connect the MINJ-1 microinjection system to a N2 or compressed air outlet instead of a high-pressure N2 tank?
A: If you are ordering a new system exclusively for use with a lab gas get, choose the Low Pressure Air Line Regulator under the regulator pull-down menu in the gree Options box above. This regulator comes with a quick-connect for 1/4-inch (6mm) Outside Diameter tubing.

You can also adapt and existing high-input-pressure system to work with a gas jet via a tubing connection to the regulator instead of using the cylinder fitting. The cylinder fitting can be unscrewed from the regulator by using a wrench on the flat part of it and unscrewing it counter-clockwise. That will expose a 1/4 NPT female port. We have a tubing quick-connect fitting that will screw into that port, or you can get any fitting you'd prefer. Our item number for the quick-connect:

MINJ-14NPT14QC: 1/4 NPT Male to 1/4 inch O.D. tubing Quick Connect fitting (special order - not on website, usually in stock) Please call or e-mail and we'll be glad to get you the fittings needed so that your system is ready to connect to what you have available.

This fitting accepts 1/4" outside-diameter tubing. We have the tubing, as well:

TT-1-4OD: 1/4" OD / 1/8" ID Clear Polyurethane Tubing

Q: Can the MINJ-1 deliver volumes in the picoliter range?
A: The MINJ-1 has no problem delivering volumes in the picoliter range. The delivery range is based on the needle tip diameter along with the pressure and time. Sharp needles with tips in the 1 micron range easily deliver picoliter volumes.
