The main features of a small vacuum freeze dryer are:
The drying room adopts high transparency, colorless and transparent organic glass doors, which can clearly observe the process of material changes during operation;
An optional eutectic point testing device is available.
Equipped with manual and automatic working modes, it is possible to manually explore the freeze-drying curve of new materials
Touch screen operation, PID control, display drying curve;
Pre freeze drying is carried out in situ, reducing the tedious operation of the drying process and achieving automation;
Shelf temperature error ≤ 1 ℃, uniform drying effect
Square pallets are not easily deformed, easy to operate, and easy to clean;
Configure an inflation valve that can be filled with dry inert gas;
It can store 20 programs, each with 36 segments. The freeze dryer can modify program parameters during operation and record the final drying curve;
The shelf temperature can be adjusted, controlled, explored, tested, and produced using advanced technology;
Due to the separate structure of the drying chamber and the cold trap, it has strong water capture ability and short drying time;
