These B.O.D. Incubators are designed especially for close control of cubation storage temperatures. These are used for B.O.D. tests storage of sensitive culture vaceines etc. culture of bacteria micro organision and plant life seed gerimination work, serum in cubation studies and immunological work etc, constructed of double walls. The exterior is made of sheet steel flusher fitting in suited door has magnetic gasket the timer chambers is made of stanless steel the pixel glass inner door makes it possible to inspect specimens without distrubing the temperature. A compartment is formed at the back of interior into which is fitted the refrigeration evaporator heater and powder ful centrifugal forced air circulator for exeating positive air flow through the incubator. A hermetically seeked compressor housed below the incubator provides temperatures below ambient, bullfin safety thermostate prevente damage to samples in case of temperature controller malfunctionig all controls are comprising selfilluminated mains On/Off switch heat energy regulator, solid state fully automatic digital electronic temperature controller-cum-indicator indivating lamps and protective fuses the bacteriological incubators are designed for close control of incubation / storage temperature in the range from 5DegC above ambient upto 60DegC accuracy +/- 0.5DegC. Inner Chamber Stainless Steel.
