Self cooling table top centrifuge

Abstract

In a table top centrifuge of the type including a rotor and a housing defining a chamber for the rotor, the housing having a removable cover therefor, there is disclosed an improvement wherein the cover has first and second passageways extending entirely therethrough, from the center and periphery, respectively, thereof to spaced locations on one of the outer surfaces thereof to define inlet and outlet ports, respectively. A refrigeration unit is provided having a cold air outlet port and a warm air inlet port at spaced locations on one of the outer surfaces thereof, the spacing between and orientation of the centrifuge and refrigeration unit inlet and outlet ports being such that positioning of the one outer surfaces of the centrifuge and refrigeration units in contact with each other aligns the outlet and inlet ports of the refrigeration unit with the inlet and outlet ports, respectively, of the centrifuge. This arrangement forms a continuous, recirculating air passageway between the refrigeration unit and the centrifuge chamber with the centifuge rotor acting as the circulating centrifugal blower.
