MAIN FEATURES
-
Process Control
-
Freeze Drying Process
Loading → Primary Freezing → 1st Drying Process → 2nd Drying Sublimation Process -
Manual Control
Make input of condition and parameter for the process from Freeze to 1st/2nd Drying Process. Process is finished after checking completion of drying. -
Automatic Control
Select recipe. Parameters of Pre-Freeze ~1st/2nd Drying Process are automatically set up. Process is completed by P-rise test system inside of chamber after whole process is finished.
