Abstract: A heating device for a titration plate enables selected sample wells to be thawed by providing an array of individually energizable heat sources each capable of heating a single sample well. A cold plate serves to maintain all other samples in their frozen state.

Abstract: The weight of a pivoted body is counterbalanced by a spring acting on a cam connected to that body to pivot therewith. A band, connected to that spring, attaches to the cam and wraps around the cam. The cam's profile is contoured to produce moment arms of various lengths, through which the force of the spring acts, balancing the variable torque of the weight of the pivoted body.
