  • Thermal cycler
    Patent number: 6558947
    Abstract: A thermal cycling device for a titration plate enables selected sample wells to be individually subjected to heating and cooling cycles independent of the temperature of adjacent sample wells. Each sample well is fitted with its own mechanism for independently heating and cooling the sample therein while a heat sensing mechanism provides feedback to the controller. The device is especially well adapted for enabling elected samples in a single titration plate to be simultaneously subjected to different PCR programs.

  • Thawing station
    Patent number: 6106784
    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.
