ABSTRACT:
A temperature-controlled centrifuge in which a heat exchanger is attached to the bottom portion of the centrifuge bowl to remove heat from the bowl and materials within the bowl interacting therewith. In one embodiment, a heat exchange plate having a plurality of substantially annular channels is appropriately attached to the bottom of the centrifuge bowl and has a surface which is thus substantially coextensive therewith. Each of these channels are positioned at different radial distances from the central axis of the heat exchange plate and each extends substantially about such axis. An appropriate heat transfer medium may thus be circulated through each of these channels to thereby substantially control a temperature across the entire bottom of the bowl. The heat transfer medium may be provided to each of the channels by a common feed inlet which also allows for the use of flow regulators where appropriate, and the heat transfer medium may also thus be removed from the channels by a common dump line. Consequently, coaxial conduits may interact with the bottom portion of the heat exchanger for interconnection with the common feed and dump lines.
