Start Degas
Prep [n] > Start Degas
Parts and accessories are located on the Micromeritics web page.
This option allows the degassing of up to six samples simultaneously. A sample can be added to any idle port and a degas operation started. When adding a sample, the degas operation in progress will be suspended until the sample reaches the target pressure, then degassing on all ports will resume. If other samples are still in the initial evacuation phase, the new samples will wait until the fast evacuation is started. Samples can be removed from any of the six ports without disturbing the degas operations already in process. Starting several samples as a batch allows them to perform the initial evacuation at the same time.
Degas conditions remain the same from degas to degas unless the Degas Conditions file is changed or replaced by the operator. A manual evacuation can be performed on any idle degas port. The six ports are represented by row numbers. Ports that are busy are grayed out and disabled.
