LEEC Research and Standard CO2 incubators set advanced standards in performance and freedom from contamination. The two Research models have the added benefit of a high temperature decontamination facility (95°C). ADVANCED MICROPROCESSOR CONTROL The specially developed microprocessor controller gives the user day to day control over all alarm settings, alarm delay and calibration adjustment. These settings are protected by an anti-tampering procedure. Sensors placed within key areas of the chamber constantly monitor and enable the control system to optimise temperature and CO2 levels. After door opening, the culture conditions quickly recover without overshooting, and stable control is maintained. Profiled heating, a technique developed by LEEC, eliminates all risk of "hot-spots". LEEC GA CO2 incubators (regardless of age) can be cooled when connected to a LEEC self contained recirculating cooler unit. ACTIVE CONTAMINATION CONTROL All models have fan assisted uni-directional airflow in the chamber, an in-line HEPA filter and an ultra smooth stainless steel chamber with rounded corners. Indirectly heated inner glass door(s) remain condensation free. These features all help to reduce the risk of contamination. The two Research models (GA2000 and GA3000) also have a high temperature decontamination facility (95°C) which is operated by a key. User experience has shown high temperature to be especially effective in eliminating culture contamination.
