The Grant-bio PCH personal bench top cooler/heaters are 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.
Two models are available, offering a choice of tube configurations, to meet the needs of many standard laboratory procedures:
PCH-1: 12 x 1.5ml plus 20 x 0.5ml micro tubes
PTR-60: for 48 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:
heat up time, RT to 100°C:
less than 10 minutes
cool down time, 100°C to RT:
less than 12 minutes
cool down time, RT to -10°C:
less than 11 minutes
A reaction timer is incorporated for convenience, with an audible alarm to signal time-up. The PCH is easy to use, with independent temperature and time operation, and straightforward setting of the two parameters. The two line LCD status display clearly indicates both set and actual values for temperature and time.
The Peltier effect produces efficient cooling and heating for small thermal loads without the use of a refrigeration system. The dry temperature control system maintains a clean working environment, reducing the chance of contamination or sample dilution. A Peltier system, without the vibration of refrigeration or the turbulence of a water bath, is also ideal for all incubations where stable conditions are critical.

PCH-1, 2 cooling / heating dry blocks
Applications
Suitable for cooling and heating applications in many different fields, with specific applications including:
 storing frozen restriction enzymes
nick translations
ligation reactions
restriction digests
protein solubilisation for PAGE
warm incubation of microcentrifuge tubes for hybridisation
cooling blood samples prior to coagulation testing
enzyme reactions and deactivations
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.
