Dry blocks for heating and cooling Dry block heating/cooling systems » PCH-1, PCH-2 and PCH-3 Dry block heating/cooling systems PCH-1, PCH-2 and PCH-3 Compact, flexible, easy to use systems for rapid heating and cooling of microtubes; very effective tools for DNA/RNA sample preparation techniques. Ⅲ Cooling/heating setting range from -10°C to 100°C, with very rapid cool down and heat-up times Ⅲ Stability ±0.1°C Ⅲ Choice of three models: capacity for up to 32 year warranty microtubes in a combination of two sizes (PCH-1) or up to 20 microtubes of one size (PCH-2 and PCH-3) Ⅲ Convenient integral reaction timer with audible alarm Model PCH-1 shown Ingenious block construction, combined with powerful Peltier cooler, produces very rapid heating and cooling Dry temperature control system maintains clean and aerosol-free environment 2-line LCD display clearly indicates both set and actual values for temperature and time Simple push button combinations for easy set-up PCH-1 Block holds a combination of two microtube sizes simultaneously – up to a total of 32 tubes: 12 x 1.5 ml plus 20 x 0.5 ml PCH-2 up to a total of 20 x 1.5 ml mictrotubes PCH-3 up to a total of 20 x 2 ml microtubes Rapid DNA denaturation at 95°C quickly achieved DNA denaturation techniques further supported with an audible alarm for denaturation ‘time-up’; samples can then be quickly cooled Ⅲ Life-science - storing restriction enzymes, nick translations, ligation reactions, restriction digests, protein solubilisation for PAGE, warm incubation of microcentrifuge tubes for hybridisation, enzyme reactions and deactivations Ⅲ Clinical - cooling blood samples prior to coagulation testing © Grant Instruments (Cambridge) Ltd
