Abstract
A sample cooler includes a cooling device such as a Peltier device and a rack for supporting vessels containing liquid samples. The rack is made of both a heat conducting material which is in a heat-communicating relationship with the side walls of the vessels and a thermally insulating material contacting the bottoms of the vessels such that the cooling device serves to cool the liquid samples through the heat conducting material and through the side walls of the vessels, not through the bottoms.
Claims8
