Praying Mantis™ Low Temperature Reaction Chambers (UV-Vis-NIR) - CHC-VUV-5

Diffuse reflection spectroscopy is a very sensitive method for detecting changes at the surfaces of rough materials. It is particularly effective for powders that have high surface areas. This makes diffuse reflectance invaluable for studies of heterogeneous catalysis, gas-solid interactions, photochemical reactions, and oxidation mechanisms. This Low Temperature Reaction Chamber is well suited for performing such studies under carefully variable temperatures and pressures. These Low Temperature Reaction Chamber allow diffuse reflection measurements under a wide range of controlled temperatures and pressures and are used in conjunction with the Praying Mantis Accessory for FT-IR and UV-Vis diffuse reflectance spectroscopy.

Features

• Designed for studies from high vacuum (133 μPa or 10^-6 torr) to 133 kPa (1 ktorr) and at temperatures from -150°C to 600°C (under vacuum).
• Three inlet/outlet ports provided for evacuating the cell and introducing gases.
• Made of chemically resistant 316 stainless steel.

Includes

• Reaction Chamber
• Low-voltage heating cartridge.
• K-type thermocouple.
• Sample packing tool and spill tray.
• Dome with two KBr windows and one glass observation window (FTIR configuration)
• Dome with two SiO₂ windows and one glass observation window (UV-Vis-NIR configuration)
