This system meets all your dissecting Microscope needs. The magnification changer ring allows you to switch between 6x, 12x, 25x, 50x magnification of the Eyepiece/Objective combination with the turn of your fingers. The lenses are ground and mounted so precisely that it is seldom necessary to re-focus when switching from one magnification to another. Illumination from above is ideal for micro-surgery, dissection, Drosophila and plant genetics, while illumination from below is ideal for Nematode and fungal genetics and micromanipulation.

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 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.
With our optional electronic Pulse-Length Control Module (PCM) you can set injection times from 0.1 to 10 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.
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.
As an added option to the microINJECTOR System you can hold your target
with our state-of-the art Holding Pipette Controller (HPC)
The HPC allows you to pick-up and hold your target with vacuum suction
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. Ideal for holding and manipulating
targets such as embryos and oocytes. Also useful for injecting ES cells
into Blastocysts. As any of our customers will attest, within a short time
you will be proficiently getting transformants.

microMAGNIPULATOR
AND STRAIGHT ARM NEEDLE HOLDER
At last there is a versatile micromanipulator for under $1000! The microMAGNIPULATOR uses the same principle as the most expensive microscope glide stages to allow you to accurately position your needle for microinjection. The surfaces of both the sliding needle positioner and glide base are teflon coated for smooth movement, and held together by a powerful, adjustable magnet capable of pulling with over 100 pounds of force. The glide base is a 4" solid steel cube that weighs 20 pounds. Its mass and no-slip elastomeric feet help to dampen vibrations. X-Y control in the 10 micron range is accomplished either by pushing the sliding needle positioner directly with your hand, or via threaded push bolts. Z control is accomplished using a fine threaded adjustment knob. Over 3 cm of X and Y movement and over 1 cm of Z movement are possible. The verstile needle positioning stand can be user-configured in a variety of ways to hold your needle at the height and angle you prefer.
And, what goes between the Tritech Research microINJECTOR and microMAGNIPULATOR (or anybody else's microinjection/micromanipulation system, for that matter)? You need a high-quality Straight-arm Needle Holder to couple the pressure to your glass capillary needle, and the needle to the micromanipulator. Now you don't have to pay $150 for Leitz-style compression fitting Needle Holders, because you can get our solid brass, silicone rubber compression fitting Needle Holder!
