Highlights

• Programmable controlled temperatures from -190^oC to 250^oC (Stability ±0.1^oC)
• Dewar cooling system
• Heated external windows prevent condensation
• Flow mode for liquids
• Solid sample gas exchange capability
• Baseplate or 3" x 2" mounts

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.
