Embodiment Construction

[0075] figure 1 An exploded view of an assembly 10 according to a first embodiment of the invention is shown. The assembly includes a sample block 12 . The sample block 12 is substantially in the shape of a stone. The sample block 12 includes one or more recesses 14 . The sample block 12 is shown as an example only, comprising six recesses 14 evenly distributed throughout the sample block 12 . More particularly, the recesses 14 are arranged in two parallel rows, wherein each row comprises three recesses 14 . It goes without saying that the sample block 12 may comprise more or less than six recesses 14 . Each recess 14 is configured to receive a sample container (in figure 1 not shown in detail). The recess 14 is conical. In particular, each recess 14 is shaped such that an aperture 16 is formed at an apex 18 in an upper surface 20 of the sample block 12 with a tapered tip 22 protruding from a lower surface 24 of the sample block 12 . Optionally, each recess 14 includes...

Abstract

An assembly (10) comprising a sample block (12), a heat sink (30) and at least one electrodeposited thermo electric element (48) is disclosed. Further, an instrument and a method for performing a temperature-dependent reaction are disclosed.

Description

technical field [0001] The present invention relates to an assembly, to an apparatus for performing more than one temperature-dependent reaction and to a method for performing a temperature-dependent reaction in an assembly. Background technique [0002] An assembly in the sense of the invention comprises a sample block, a heat sink and at least one thermoelectric element. Such a sample block is configured to accommodate at least one and preferably a plurality of sample containers. Thermoelectric elements are designed as thermoelectric coolers or thermoelectric heaters. Thermoelectric coolers use the Peltier effect to create a heat flux between the junction of two different types of materials. Peltier coolers, heaters, or thermoelectric heat pumps are solid state active heat pumps that transfer heat from one side of the unit to the other depending on the direction of electrical current, while dissipating electrical energy. Such instruments are also known as Peltier device...
