Grant PCH Cooling Heating Dry Blocks for Microtubes

Ideal for laboratory applications requiring cooling and heating in microtubes within the temperature range of -10 to +100°C. The PCH cooler/heaters enable a stable temperature to be maintained during room temperature fluctuations.

Three models are available, offering a choice of tube configurations.

• PCH-1: 12 x 1.5ml plus 20 x 0.5ml microtubes
• PCH-2: 20 x 1.5ml microtubes
• PCH-3: 20 x 2.0ml microtubes

The ingenious block construction, combined with the powerful Peltier module, produces very rapid cooling and heating for swift change of application and increased flexibility. A reaction timer is incorporated for convenience, with an audible alarm to signal time-up. The Peltier effect produces efficient cooling and heating for small thermal loads without the use of a refrigeration system.

The PCH is a very effective tool for DNA sample preparation for denaturing electrophoresis. The exceptionally rapid heat up enables the denaturation temperature of 95°C to be reached swiftly, the timer will signify denaturation time-up, and the samples can be rapidly cooled again ready to load the gels.
