Note: As of September 2014, we have upgraded our incubators to use a higher-quality, more robust 38-liter enclosure. While it is slightly less deep from the door to the back wall, the height and width remain the same and it has a superior door seal, internal recirculation fan and heat pump assembly.

Never before have incubators with all these features been offered for such low prices. Tritech brings the ultra-high-tech Microprocessor controlled, solid-state heating/cooling (refrigerated) incubator down to earth.  This incubator is ideal for bacterial, insect, and plant cell culture.  It is ideal for maintaining small stocks of C. elegans worms, Drosophila flies, rearing Xenopus frogs and Zebrafish, and hatching reptile eggs.  Your research deserves the best incubator, and now you can afford it.  At this price, you can keep your lab happy by having more than one incubator, eliminating the risk of spreading contamination between experiments and making it easy to run experiments at different temperatures simultaneously.

  • Microprocessor-controlled for reliability and ease of use
  • Lightweight enough to be portable; mobile and battery backup options available
  • User-friendly, yet sophisticated, alarms alert you if the incubator falls out of desired parameters, even if due to the door being left ajar.
  • Fast Temperature Parameter Recovery.
  • Nearly silent operation with ultra-low vibration
  • Energy Efficient - draws less than 100 watts at maximum heating or cooling
  • Excellent for Near-ambient temperature incubations - uses energy only as required
  • Easy to calibrate to your own NIST-traceable thermometer
  • Stores parameters for fast auto-recovery after a power failure
  • 38L model weighs less than 30 lbs (13 kg)

Modern design with upgradeable microprocessor for specialty applications, such as:

  • Integrated, timed lighting system for Circadian experiments.
  • Automatic ramping or switching between temperatures.
  • Temperature data logging.
  • Complete I/O module for bidirectional communication / control with a computer.
  • Almost anything else you can think of -- call us with your ideas!

In order to help you optimize space in your research lab, Tritech Research's stacking Rack (DT2-STACK) for its 38L Incubator allows to stack incubators on top of each other. The maximum recommended number of incubators to stack on top of each other is three (and requires 2 racks).

Q: I set the incubator to a certain temperature, but it differs from the temperature of my own reference thermometer. Is there a way to calibrate the incubator?
A: The first thing to do is to make sure the temperature sensor and your thermomete are placed well. See what happens if both your thermometer and the probe are near the middle of the top shelf. If you find that the calibration is really not to your liking, it is easy to change. One of the menus is "T-Calib." You can put in an offset (instead of 0.0) to make the display agree with your reference thermometer, and then the incubator will do its controlling based on that. Remember to wait at least 1 hour for the incubator to adjust to your new setting.

Q: Can DigiTherm incubators control internal humidity?
A: TriTech incubators do not claim to be able to precisely maintain internal humidity, but they are quality controlled to ensure that they are closed systems which do not circulate outside air. As a result, 70-80% internal humidity can be maintained fairly consistently when a water tray is placed inside.

Q: What type of light is used in the DigiTherm incubators?
A: The light inside the incubators that is used for the circadian lighting option is a cold-cathode compact fluorescent light. It is a small fluorescent tube which produces a cool white light. The 12-inch bulb runs vertically up the back wall of the incubation chamber.

Q: What makes the DigiTherm incubators unique from other incubators?
A: The standard DigiTherm heating and cooling incubator is able to heat and cool its interior within 0.1 degrees of precision. It can heat and cool with in 15 degrees (delta) from the ambient temperature, a feature that no other incubator on the market has. They are super-reliable and user friendly. The incubator will alert you if the interior conditions fall outside of your parameters for any reason. You can choose to order an incubator that is capable of circadian lighting and circadian temperature control cycles to your specification via computer interface.

Q: What does exactly does the new Light Tight door covering option DT2-DARK entail?
A: While our 38-liter incubators are nearly opaque, they are not perfectly opaque. For example, if bright sunlight shines directly on the door, we are able to measure some light with the sensitive light sensor that we include in our DT2-CIRC-TK incubators. If we put a bright light inside the incubator, and look in total darkness, we are able to see some small light leaks through the door and around the door.
Proportionately, compared to the light level when our internal light is on, the level of the light leaking in is like comparing daylight with starlight or moonlight at night. In a normal lab environment with fluorescent lighting, there is much less light leaking in as compared with the example of direct sunlight. However, for labs that are concerned about even small light leaks (for example for experiments that involve circadian entrainment followed by continuous darkness) we offer a two-part modification. For the $90 option, we affix a sheet of blackout vinyl to cover the door and add opaque gasket material around the door frame and manually inspect the incubators in a darkroom to cut light leaks to an absolute minimum.

Q: My incubator is experiencing time jumps where the incubator time differs from the environment time. What could be causing my incubator to constantly restart and how can I prevent this?
A: When your incubator loses power, even for less than 1 second, or experiences major power fluctuations, it will restart and load the last time value that you previously set. The easiest way to know that your incubator has restarted is when the incubator powers up, its display will only show the temperature, no time. If you have trouble depending on the building power supply, we suggest that you add our battery back-up version to your order or add a type of Uninterruptible Power Supply (UPS) that you can buy for a computer, and plug your incubator into it. Another possible issue that can cause your incubator to reset is a large electromagnetic pulse. This can occur sometimes if your incubator is plugged in near a device that generates a lot of electrical noise (freezers, motors, fluorescent lights). Try plugging your incubator into its own outlet or a surge protector power strip. Or you can try moving your incubator further away from such equipment.

Q: Where are the heating and cooling elements located in the incubator?
A: 100% of the electronics and heat pump are located in the top of the incubator; therefore, custom holes can be in the sides, back (and the bottom and the door, although those locations are less practical).

Q: Can more than one lightbulb be added to the incubator to make it brighter?
A: We sell the light tubes and the high voltage power supplies that step up the voltage for them. The power supply has jacks for, and is usually able to power, 2 of the light tubes. Each light tube generates about 4 watts of heat. To prevent the incubator from overheating, we recommend a maximum of 2 light tubes per incubator.

Q: What are some ways to reduce condensation from collecting on samples (such as fly bottles) within the incubator?
A: Since our incubators primarily recirculate the inside air, samples tend not to evaporate and humidity remains high, which can lead to condensation in some cases. Sometimes putting your bottles on the bottom shelf helps with that. The top of the incubator may be a bit hotter than the bottom causing more moisture from samples at the top. It is also possible to drill one or more holes in the incubator to let some moisture evaporate out into the room.

Q: What is the recommended practice for attaching the sticky feet to the incubator?
A: We recommend putting the sticky feet on the bottom of the incubators so that they are less likely to slide when pulling or pushing on the door. If you also purchased a stacking rack, rack legs generally come with a double-stick adhesive foam on both sides. After you are happy with the position and direction of them (so that the rack is level and doesn't wobble) you can peel the protective layer off of the foam and stick them to the rack and the incubator top. Please ensure that the bottom incubator is stable and not wobbly before positioning the stacking rack.
