Atmospheric control unit for microplate readers
BMG LABTECH - The Microplate Reader Company

The Atmospheric Control Unit (ACU) first released in the UK in August 2009, provides fully regulated independent control of both O2 and CO2 levels within the read chamber of the Omega series of microplate readers. In combination with the temperature control and unrivalled shaking options of the Omega series, this option provides a true ‘walk away’ solution for long term cell based assays.

O2 levels can be programmed into the system between 1 - 19%, such conditions are created by using Nitrogen to purge the O2 from the system. The concentration is monitored and maintained using a calibrated electrochemical sensor that provides accurate control. CO2 can be added to the chamber and is monitored using a sensitive infra red sensor giving accurate control of CO2 between 0 - 20%. The superior control of the valves regulating the gases ensures that once the reader is equilibrated there is a minimal consumption of gases.

Unique to the Atmospheric Control Unit, the gases are regulated independently, meaning that any combination can be programmed without the need to change the cylinders or piped gas supplies.
