Abstract

See full text

Independent control of multiple samples which are in close proximity. All the samples in a sample container designed for rapid heat transfer and can be independently regulated to a set point using a temperature feedback control with the temperature monitored by a temperature sensitive element. This is implemented by heating each sample independently and at the same time a cooling device produces a substantial and continuous heat flow from the sample in order to permit an adequate rate of cooling when required. The rate of heat flow through the cooling device is partly determined by a thermal resistance which is included to control the pattern and maximum rate of heat flow to designed levels. By keeping the thermal mass of the temperature controlled components to a minimum it is also possible to change the temperature of the samples very rapidly.
