- Programmable controlled temperatures from -190oC to 250oC (Stability ±0.1oC)
- 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 -190oC to 250oC.
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 -190oC to 250oC 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.
