1. An assembly for simultaneously confining multiple samples in separate chambers during thermal equilibration, comprising:

  • a plate defining a plurality of containment wells, each well having an opening at a principal surface of said plate;

    a compressible gasket disposed on and extending over the majority of said principal surface of said plate, said compressible gasket having a plurality of holes in register with said wells; and

    a lid disposed on said compressible gasket, said lid having a surface for compressing said compressible gasket on said principal surface of said plate to form a seal and close said wells to define individual closed well chambers, thereby preventing said samples from flowing from one well chamber to another between said lid and said principal surface of said plate during thermal equilibration.
