End point determination

Temperature difference can be used together with optional product temperature sensors to determine the end point.

Sample protective state

If the sample temperature rises above the set collapse temperature or the pressure is outside the safety range then the sample pretective state is activated. This reduces the pressure and stops the shelf heating.

Flexible drying chambers

  • Adjustable shelf distance according to your application needs
