Pressurised reaction cell: The 24 ml cell can be pressurised to 2800 psi and heated to 200 °C. It features a cooling jacket and has 1/8^th inch Swagelok fittings for in-flow of reactants.
Resistant materials: The In-Situ reaction chamber can be manufactured from Stainless-Steel or Haselloy, depending on the application. The monolithic diamond ATR crystal is robust and chemically resistant.
Optional stirring device: A motorised variable speed stirrer with sapphire shaft and integrated pressure cap is available as an option.
