Abstract
A thermal chamber, e.g. for culturing bacteria, has between a pair of sidewalls, a plurality of replaceable bridge members or plates which can be formed with undulating broad surfaces or grooves to accommodate flasks so that gaps between the plates receive measuring devices for turbidity or the like. The plates are thermally conductive and abut the walls which can be provided with heating or cooling units.
Claims19
A thermal chamber for controlling temperature of a plurality of biological samples in respective measurement vessels, said thermal chamber comprising:
- a pair of spaced-apart juxtaposed walls, at least one of said walls being thermally conductive;
- means for regulating a temperature of said one of said walls;
- and
- at least two removable and replaceable mutually spaced thermally conductive bridging members in the form of solid metal plates spanning between said walls and in thermally conductive contact with said one of said walls over a contact area along an end thereof, said bridging members receiving said vessels between them in thermally conductive contact with said vessels whereby each of said vessels is in contact with two of said bridging members for homogeneously distributing heat among said vessels, said bridging members being spaced apart by distances at least equal to a width of said vessels at least at regions along said bridging members receiving said vessels.
