FCM20-  Laboratory Freeze Thaw chamber

This is a one door laboratory Freeze thaw chamber and storage freezer capable of performing in wide temperature range(-25°c to 50°c) with precise temperature control over the entire range. The  Laboratory freeze thaw chamber is ideal for customers requiring ramp soak programming, require testing their product through extreme temperature range. Typical ramping capability is 1°c per 2 min during the operating range of -23°c to 23°c under controlled ambient temperature of 20°c. Moreover this chamber can be used a Storage freezer at -25°c under controlled ambient temperature of 20°c. 

Please check out our mobile/small storage freezer model –FCM3. Also review our stability cold storage chamber and Laboratory incubator products. The Low temperature and wide temperature range is one of our popular models. Please check with our sales group for in-stock products. This model is a unique product in the market that features Thermoelectric cooling for low temp application. Lastly, this laboratory freeze thaw model does not use any refrigerant or high temp heaters but rather uses bi-directional thermoelectric module to achieve extremes of temperature. The unit is very quiet in operation , has zero global warming potential(GWP) making it a very unique model.


The Laboratory Freeze thaw chamber features all stainless steel interior and exterior construction with 2″ polyurethane CFC free insulation.

Cabinet standard features

  • Stainless Steel Exterior & Interior
  • Maintains temperatures between 4°c to 50°c
  • LED interior light
  • Recessed Door Handle
  • Door locks standard
  • Magnetic door gasket standard for positive door seal
  • Pre-Installed 4″casters with bumper brakes

Chamber uses thermoelectric assembly for heating and cooling. This type of cooling/heating system completely eliminates need for conventional refrigeration system and failures due to mechanical components such as compressors thereby drastically increasing the life expectancy of each chamber. Maintenance cost is also lowered by the thermoelectric/Peltier driven heating/cooling system. The chamber is quiet  while in operation. Chamber temperature set points are tightly controlled using PID controller.
