High Temperature Cell


Our High Temperature Cell permits transmission measurements studies of solid samples at temperatures ranging from ambient to in excess of 500°C in a controlled environment.

The interior of the cell is made from chemically resistant 316 stainless steel and is thermally insulated to prevent heat loss.  Two fittings are supplied to evacuate or flow gas through the cell.  The cell features two K-type thermocouples for temperature regulation and monitoring.  It is equipped with low-voltage heaters, compatible with the Harrick Temperature Controller, to heat the sample and a cooling conduit to reduce the temperature of the exterior of the cell during high temperature operation.

The High Temperature Cell is ideal for examining catalytic and other gas-solid chemical interactions.
