The Thermo Scientific Low Temperature Incubator 3915LT is a bench top model perfect for Biochemical Oxygen Demand or other low temperature applications and features a spacious 6.5 cu ft interior capacity with the ability to hold up to 120 standard B.O.D. bottles. Peltier Cooling Technology provides energy efficiency by eliminating the need for a refrigerated compressor and heating coils, consuming 75% less power while reducing laboratory ambient temperatures and air conditioning loads. Excellent temperature uniformity allows for effective space utilization, basically doubling usable capacity and insuring that all shelf areas are maintained at the proper temperatures as compared to other compressor driven incubators on the market. As a greener product, it uses no refrigerant gases extending the service life with no impact from projected changes for the refrigerants. Heavy duty shelves, a programmable Watlow controller, RS 485 Interface, an independent over temperature thermostat and over temperature alarm are also included. The 3915LT meets the American Public Health Association ( APHA ) Specifications for Biochemical Oxygen Demand ( BOD ) and comes complete with a 1 Year Manufacturer's Parts and Labor Warranty followed by a 2nd Year Manufacturer's Parts Warranty.
