Variable Temperature Cell Four Port Cuvette version with temperature controller and Fused Silica (UV) windows (pair) for jacket

The Variable Temperature Cell is the ideal accessory to use for the transmission study of liquid or solid samples at various temperatures ranging from -190^oC to 250^oC.

The Variable Temperature Cell consists of a vacuum jacket with standard NaCI windows which contains a refrigerant dewar/cell holder assembly. Sample cells are inserted into the haeting block part of the dewar/cell holder and the whole is operated within a vacuum enviroment 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 independant control using a personal computer.

Special versions of this cell have been designed for use in Raman and Fluorescence applications. These cells use four ports and samples are contained in cuvettes or bulbs.
