Heat distributor for a number of blocks at different temperatures, for DNA samples for PCR, has a swing mounting plate for the blocks together with a lifting mechanism and return lever

摘要

The heat distributor (1) to serve a number of heating blocks (2), to maintain DNA samples at different temperatures in cycles for PCR . The heating blocks are on a swing mounting plate (4) with an insulation cuff (12), with the swing axis aligned at the thermal coupling surfaces. The blocks also have a sliding movement through a lifting mechanism (24), with a return lever (17) fitted with an electromagnet (19).
