In typical operation, this chamber is used to condition multiple Charpy impact specimens at the same time as a batch at one controlled setpoint, so a full series can be stabilized before transfer to the impact tester.

The practical number of specimens you can condition simultaneously depends on how you configure the load for consistent cooling and temperature stability. Key drivers are specimen size (full-size vs sub-size), how much spacing you maintain for uniform circulation, and the target temperature you are running, with NG-ISCC models available for conditioning down to -196°C depending on the version selected.

For repeatable results, most labs avoid overcrowding and keep the same loading pattern from run to run so the soak and temperature uniformity are consistent.
