Abstract

A forced air heating apparatus for providing automatic cyclical heating and cooling of biological samples includes a housing and a heating chamber within the housing. The heating chamber supports a biological sample tray for supporting a plurality of sample containers. A heating device and an impeller are provided to heat the heating chamber and to direct heated air over the sample containers. The heating chamber is sealed to prevent escape of materials and includes a vent coupled to a filter to maintain ambient pressure in the heating chamber and trap particulate materials passing through the vent.
