MICRO THERMAL CYCLER WITH SELECTIVE HEAT ISOLATION

摘要

A temperature controller (10) for the reaction chambers of a microfluidic chip or lab on a chip is disclosed' with an insulator block (11) which supports the chip (not illustrated) and metallic heat conductors (12) positioned in vias in the insulating block that coincide with the positions of the reaction chambers of the microfluidic chip. Locking means (13) hold the chip in position. A cooling/heating block (14) such as a Peltier element provides the thermal changes which spreads by conduction up to the vias to heat the reaction chambers of the chip. A heat sink (15) with eg cooling fins dissipates unwanted heat.
