Model SRI3P B.O.D. Thermoelectric Cooled Incubator, 3.5 cu.ft. (84 Bottle) capacity. Using innovative thermoelectric cooling technology, the SRI3P eliminates the need for a refrigeration compressor. This means that these units use 71% less power than alternative models and reduce room air conditioning loads by 75%. They also include 35-pound capacity shelves, which eliminates sagging.
SRIP incubators meet APHA specifications for Biochemical Oxygen Demand (BOD) and include a mechanical convection system to ensure even air distribution, a digital temperature set controller, over-temperature limit control, and a digital temperature display.
A one-amp interior outlet allows the use of shakers, stirrers, roller bottles, or other apparatus. Units are supplied with adjustable leveling feet.
