Thermo block groups and instruments, the low thermal non-uniformity providing, for the rapid alternating thermal stress

摘要

Thermo block group for thermocycling, with:a sample block a first surface and a second surface, the first surface for receiving a sample support device is suitable for;a heat sink, which comprises a base with a first surface, and a second surface and a plurality of ribs, which depend on the second surface, with a space between each rib provides for a flow path for air from an inlet side of the plurality of ribs to an outlet side of the plurality of ribs without collision; anda plurality of thermal electrical devices, which is disposed between said sample block and the heat sink are positioned, with the base area of the plurality of thermal electrical devices can be effectively with the base surface of the second surface of the samples block and the first surface of the heat sink, about a substantially uniform heat transfer in all cases to provide the thermo block group.
