First Claim
Patent Images
1. An apparatus for thermally cycling, the apparatus comprising:
- a sample retaining element comprising an upper surface and a bottom surface opposing the upper surface, wherein the upper surface is configured with a plurality of cavities, capable of receiving a plurality of sample wells, wherein each sample well can contain at least one biological sample, and wherein each cavity comprises a closed bottom, an open top and connected to adjacent cavities by ribs that form voids between the cavities;
at least one thermoelectric module coupled to the retaining element; and
a heater adhesively coupled to an edge surface in close proximity to the cavities located between the upper surface and the bottom surface of the sample retaining element.
