Key points for selecting low-temperature dehydration equipment for heat-sensitive materials
Before choosing operating conditions for low-temperature dehydration of heat-sensitive materials, define the observable material result and the actual load.
For heat-sensitive materials, establish deformation or degradation limits and judge dehydration from both sample temperature and residual moisture.
Equipment decisions
-
Specify absolute pressure and gauge location; a pump ultimate-pressure rating is not the chamber operating pressure with a wet load.
-
Check sample and tray contact with heated surfaces. Heat transfer changes at low pressure, so the sample core can still be warming after the controller reaches setpoint.
-
Match pump, seals, cold trap or condenser to the released vapour. A standard vacuum-oven configuration does not establish suitability for flammable solvents.
-
Determine completion from material endpoints such as residual moisture, solvent residue or constant mass; record sample temperature, operating pressure and moisture regain after venting.
Trial and acceptance
Record the initial sample condition, loading layout, recipe version and raw measurements. Agree the acceptance endpoint before the trial; repeat at challenging load positions and compare the finished material result.
