DigiTherm® Microscope Stage Temperature Control Kit

  DT3:  $810.81 - Special Order
Image for DigiTherm(R) Microscope Stage Temperature Control Kit coming soon!
The DigiTherm® Temperature Control Kit lets you precisely heat or cool almost anything. It is ideal for controlling the temperature of samples on a microscope stage, and has capabilities superior to systems from other manufacturers costing thousands of dollars.

     You get the reliable Tritech DigiTherm Temperature Controller and 12 volt high current power supply found on our incubators, coupled to a pair of solid state Peltier Effect Thermoelectric heat pumps. Each heat pump has it's own mini heat sink and fan to dispose of heat pumped out of your apparatus, or collect heat from the environment to pump into your apparatus, depending on your requirements.

     The heat pumps can attach directly to a microscope stage, a metal plate, or a small container to control the temperature of a solution. Custom made plates, for example to control the temperature of a particular size of Petri dish or cell culture flask are also available. If you need us to mount our heating kit directly to your existing microscope we can provide this service.

Basic Kit: $750.00† (Additional heaters/fans/peltiers, available upon request)



FAQ's

Q: What types of microscope stage temperature controllers do you have?
A: The DT3 is the custom-made controller and power supply for all of the custom-made stages we produce. Some versions are heating-only, and some are heating and cooling. Some use resistive heating, some use peltier-effect thermoelectric heat pumps, and others use a variable speed coolant pump and coolant channels in the stage. Please let us know what your application entails, and we would be happy to design or recommend the perfect system for your work.

Q: What are my options for a temperature controller that alternates between two temperatures?
A: There are two options for going between two temperatures.
1) We have a dual temperature version of the controller that allows you to set 2 temperatures and a transition time. It switches from Temp1 to Temp2 at the appropriate time; however, the ramping rate is variable and not controllable.
2) We have a version of the controller with a bi-directional computer interface, and software that allows for user-programming of temperature ramps of arbitrary complexity (within the physical limitations of the controller and its power rating).

DigiTherm® Microscope Temperature Control Air Bath

  DT3-BL:  $1,729.73 - Special Order
Image for DigiTherm(TM) Microscope Stage Temperature Control Air Bath coming soon!
The DigiTherm® Temperature Control Air Bath lets you precisely heat almost anything. It is ideal for controlling the temperature of samples on a microscope stage, and has capabilities superior to systems from other manufacturers costing thousands of dollars.

You get a customized version of the reliable Tritech DigiTherm Temperature Controller coupled to a high power heat blower.

The unit can be aimed directly at a microscope stage (from above or below), to surround your samples and microscope optics with temperature controlled air! This is particularly important for high magnification experiments where the objective lens touches and heat-sinks the sample.

FAQ's

Q: Does this system provide high temporal precision in cooling down a small volume of air surrounding specimen such as a mouse forepaw?
A: The DT3-BL airbath is designed to slowly adjust its warm air output to surround a microscope stage area and sample with temperature controlled air. It has a fairly large temperature sensor that is to be placed in the target area for feedback regulation. For both of these reasons, it may not be well suited for your experiments.
We might be able to custom-make something that would work for your specific experiment. A solid-state infrared light source combined with slow continuous room-temperature air movement and a non-contact infrared thermometer might be appropriate. If you can accept a contacting system attached to the forepaw, a small peltier-effect thermo-electric heatpump and miniature temp sensor would work. You could use our regular DT3 controller (with it's optional bi-directional computer interface and software) to experimentally determine the right amount of power to send to the heatpump to get the desired heating, cooling, and ramp speeds.

PappaCooler® -80 Cryo-Preserver

  PPC-1:  $74.59 - In Stock
Image for PappaCooler® -80 Cryo-Preserver coming soon!
Don't go through the hassle and expense of running around to get liquid Nitrogen, or dry ice and ethanol or acetone, every time you want to quick-freeze your samples. With our PappaCooler® and an -80°C freezer you can always be prepared.

     Store the PappaCooler unit in your freezer. Bring it to your bench when you are ready to quick-freeze your samples; insert them in the unit and they are frozen. The design has been optimized to produce ultra-high-efficiency frozen competent cells and to give high survival rates when Cryo-preserving prokaryotic and eukaryotic cells.

     Not only will you be saving time and money using the PappaCooler, but you will also be saving the environment from solvents and gases that require lots of energy to produce. The PappaCooler is made partly from recycled materials.

DigiTherm®160-channel Temperature Datalogger

  TDL-160:  $6,918.92 - In Stock
Image for DigiTherm(R)160 channel Temperature Datalogger coming soon!
The DigiTherm® 160 Channel Temperature Measurement and Data Logger lets you precisely monitor and log the temperature of 160 separate locations at once. We like to come up with memorable names for our products, so we call it the HectoHexeContaLogger™ (yes all that Greek means 160)! The TDL-160 plugs into your computer network, and then it can be controlled and data logged from any computer on the local network or on the internet. 160 numbered temperature sensors are epoxy dipped for easy cleaning and on the end of very flexible, thin wires that are up to 5 feet long for easy positioning. Simple commands allow you to calibrate the sensors to exactly the same value before starting an experiment, collect data from all 160 probes, a sub-range, or a single probe.

The system has a variety of uses including logging temperature data from many points within one or more incubators or freezers to prove temperature consistency or to show and know temperature variations precisely. It can be used with our DigiTherm® CO2 Incubator, Standard DigiTherm® Incubator, our CircKinetics™ Incubator, or any incubator, refrigerator, freezer, or coldroom that you own. This data logger unit includes firmware that outputs the data in a format that allows easy import and graphing in spreadsheets like Excel and OpenOffice, and easy control and data collection by programs like Labview.

Fisher sells the "traditional" ice buckets for $50 to $70! Unbelievable!?! Well, Tritech Research comes to the rescue with high-tech injection molded polyethylene/polypropylene mini-ice chests filled with super-insulating polyurethane foam. They have attached lids that flip open (or detach if you prefer), and they are rectangular, just like your tube racks. These coolers keep your ice from melting for a long, long time, so you don't have to worry about your samples floating away. All models have comfortable, folding handles to make carrying them to and from the ice machine a breeze. Priced at just $25 to $50, once you use them, you can't believe you put up with the old ones for all those years.
