Self-decontamination cycle ensures reliable results. Dry-wall design uses high temperatures and humidity to kill fungal spores and vegetative bacteria. Programmable decontamination can be set for 4, 5, 6 or 7 hour cycles. Laminar flow ensures consistent circulation of heated, humidified air throughout chamber. Fan inside the chamber produces mechanical convection - providing rapid temperature recovery. Lack of internal water reservoir also eliminates common breeding site for chamber contaminants. There is a digital keypad with High/low deviation alarms, non-volatile memory and electronic security lockout to effectively protect your samples. RH can be controlled from 80 to 98%. 6 cu.ft. chamber. Temperature range: 5C above ambient to 60C. Control: 0.1C. Uniformity at 37C: +/-1.5C. Uniformity at 50C: +/-0.2C. CO2 range: 0 to 20%. CO2 control: 0.1%. Includes 4 shelves. ***can also be used as a regular incubator without connecting CO2***
