The Harrick Praying Mantis™ Low Temperature Reaction Chamber is engineered for diffuse reflectance spectroscopy on rough and high-surface-area samples such as powders. It is suitable for heterogeneous catalysis, gas-solid interactions, photochemical reactions, and oxidation studies, providing controlled measurements across a broad range of temperatures and pressures.

This accessory is compatible with the Praying Mantis accessory and supports both FT-IR and UV-Vis diffuse reflectance spectroscopy. It enables precise surface analysis under regulated environmental conditions including vacuum and elevated pressures.
