Temperature Controlled Concave (CC) Sample Covers and Pressers Rudolph Research Analytical’s J157 is able to control temperature quickly and accurately because it has a unique dual temperature control system where heating or cooling is applied to both sides of the sample. The (CC) Concave Sample Cover is controlled to the same temperature as the prism and, when lowered, is designed to provide a temperature controlled micro environment that provides unrivaled temperature stability, fast measurement time and minimal evaporation. Optional Contact Presser (CP Presser) The J157 Series are available...

Measurement Surface Ultra Hard Sapphire Prism Other manufacturers compromise From the pictures below one can see that other manufacturers have to make a compromise with the depth and angle of the sample well. Since these manufacturers use one sample well and cover design for all temperature applications, they end up with a sample well that is too narrow and deep. The deep sample well makes cleaning needlessly hard at ambient temperature while failing to provide ideal temperature control when the sample and air temperature are more than 10°C from the desired measurement temperature. Some manufacturers...
