Heated and Cooled Laboratory Incubators These laboratory incubators have a wider range of temperatures. Also, these might be purchased if the role of the chamber might switch in future use - for example from cooler to above ambient temperatures. We have two types of heated and cooled incubators. The DB series incubators use compressor technology and have temperature ranges of 2°C to 50°C. The TE series incubators use thermoelectric technology and have temperature ranges of 14°C to 50°C. Temperatures greater than 50°C or lower than 4°C can be achieved with optional upgrades to construction and components. Our versatile line of incubators are ideal for a variety of applications, including microbiological research and BOD studies.
