Eppendorf^® PCR Cooler 

Eppendorf PCR Cooler maintains a sample temperature of 0°C (with 2 hours pre-cooling at -20°C) for over an hour and then changes color when the temperature has exceeded 7°C. Superior to an ice bath, PCR Cooler is easy to handle, space saving and free from contamination, which makes it the perfect preparation for your PCR reactions. The temperature of single tubes is indicated by the color of the individual bores. In addition samples are prevented from freezing by the specially developed cone contour.
