Information

The Variable Temperature Cell is the ideal accessory for the transmission study of liquid or solid samples at temperatures ranging from –190 ºC to 250 ºC. The Variable Temperature Cell consists of a vacuum jacket with standard NaCl windows. Inside the cell is a refrigerant dewar and cell holder assembly. The cell holder assembly has a built-in heating block for high temperatures. Sample cells are inserted into the cell holder assembly and the whole is operated within a vacuum environment maintained by the outer jacket. Using a combination of refrigerant and control from the cell block heaters any temperature from –190 ºC to 250 ºC can be achieved. Choice of window materials allows for use of this accessory in the UV, visible and IR regions. The Variable Temperature Cell is supplied with a high stability controller with an RS232 interface for independent control using a PC. Special versions of this cell have been designed for use in Raman and Fluorescence applications. These cells use four ports and the samples are contained in cuvettes or bulbs.
