Variable Temperature FTIR Cell

Variable Temperature Cell Holder
The Variable Temperature Cell Holder is the ideal accessory to use for the transmission study of liquid or solid samples over a broad range of temperatures. The cell consists of a vacuum jacket that contains a refrigerant dewar/cell holder assembly and a heating block that contains the appropriate cell, and allows variable temperature over the range from -190°C to 250°C.

NaCl windows are provided as standard on the cell holder, but a range of other UV, Vis, NIR and Infrared transmitting window materials are also available.

This transmission cell holder is designed for use with Specac’s Advanced Liquid or Solid Transmission Cells, Spectroelectrochemical Cell, or High Pressure Liquid Cell. The cell holder is installed into an optical spectrometer sample compartment either via the 3" x 2" slide mounting plate, or with a Benchmark™ baseplate.

Note that this accessory requires an appropriate sample cell for its use, and that the temperature range of this transmission cell should be taken into account in its use.

Variable Temperature Cuvette Holder
The Variable Temperature Cuvette Holder is a four port version of the standard Variable Temperature Cell Holder, designed to accommodate quartz glass cuvettes of up to 10 mm pathlength. This cell holder is intended for liquid sample Raman, Fluorescence, and UV spectroscopic analysis. The four port nature of the design means that collection of the (scattered) radiation can be at a 90° angle to the incident radiation as well as at a 180° angle as measured with a standard configuration.

Specac’s Variable Temperature Cuvette Holder operates over temperatures from -190°C to 250°C. A pair of Spectrosil B (UV-grade fused silica) is provided as standard for two of the cell holder windows, and the other two window ports are fitted with blank (metal) windows.

The cell holder is installed into an optical spectrometer sample compartment either via the 3" x 2" slide mounting plate, or with a Benchmark™ baseplate.
