Grant PCH-1/PCH-2/PCH-3 personal benchtop cooler/heaters are ideal for laboratory applications requiring cooling and heating in microtubes within the temperature setting range of – 10℃ to +100℃. The PCH cooler/heaters enable a stable temperature to be maintained during room temperature fluctuations.

• PCH-1 - 12x1.5 ml plus 20x0.5 ml tubes 
• PCH-2 - 20x1.5 ml tubes 
• PCH-3 - 20x2 ml microtubes

The ingenious block construction, combined with a powerful Peltier module, produces very rapid cooling and heating for a swift change of application and increased flexibility. In addition, 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.

Benefits

• Cooling/heating setting range from – 10ºC to 100℃, with very rapid cool down and heat-up times
• Stability ± 0.1℃, uniformity ±0.25℃ at 37℃
• Convenient integral reaction timer with audible alarm
• Dry temperature control system maintains a clean and vibration-free working environment
• A 2-line LCD display clearly indicates both set and actual values for temperature and time. Works in combination with simple push buttons for easy set-up.
• Flexible tube sizes and rapid heat-up/cool-down times enables swift change of application

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℃ to be reached swiftly, the timer will signify denaturation time-up, and the samples can be rapidly cooled again ready to load the gels.

Applications

• Life science – storing frozen restriction enzymes, nick translations, ligation reactions, restriction digests, protein solubilisation for PAGE, warm incubation of microcentrifuge tubes for hybridisation, enzyme reactions and deactivations.
• Clinical – cooling blood samples prior to coagulation testing.
