Joe Flow - Temperature Control

Heating Up and Cooling Down

"I would like to discuss the importance of temperature control in rheology. To see how much influence the temperature has on the rheological behavior of samples, you only need to read off the viscosity values of a calibration standard at different temperatures. A difference of just one degree centigrade between two measurements leads to a 7 % deviation in the viscosity value. It is therefore extremely important to control the temperature accurately and precisely."

Which temperature device is suitable for which temperature range?

Depending on the temperature range and type of sample there are a number of temperature devices available. Today, for standard temperature devices Peltier elements are usually used. With appropriate counter-cooling, these elements can be operated from -40 °C to +200 °C.
