The Variable Temperature (VT) Cell Holder P/N GS21525 is designed for transmission studies of liquid or solid samples over a wide temperature range from -190°C to 250°C with a stability of ±0.1°C. It features a vacuum jacket housing a refrigerant dewar and cell holder assembly combined with a heating block to enable precise temperature control.
The cell holder is compatible with Specac’s Advanced Liquid or Solid Transmission Cells and High Pressure Liquid Cells, and can be mounted in the spectrometer sample compartment using either a 3″ x 2″ slide mounting plate or a Benchmark™ baseplate. Standard NaCl windows are included, with options available for other UV, Vis, NIR, and IR transmitting window materials.
