Description
Freeze-drying is a drying technique that utilizes the principle of sublimation. It involves rapidly freezing the material to be dried at low temperatures and then, under the right vacuum conditions, allowing the frozen water molecules to directly sublime into water vapor and escape. The material remains in a low-temperature (frozen) state throughout the drying process, with ice crystals evenly distributed throughout. The sublimation process does not lead to concentration due to dehydration, thus avoiding side effects such as foaming and oxidation caused by water vapor. The dried material retains a porous, sponge-like structure with virtually unchanged volume and dissolves easily in water to revert to its original state. This process minimizes the denaturation of the material in terms of physicochemical and biological properties to the greatest extent possible.Features

Taking and Placing in Layers, More Convenient:
Each shelf can be placed and taken freely without manual work. The height of each shelf can be
adjusted freely.
Special Hole Position for Centrifuge Tubes:
Conductive to the drying of samples in centrifuge tube containers.
Freeze-Drying Organic Solvent:
316L stainless steel stackable sample shelves, capable of freeze-drying organic solvent and various corrosive solvents.

Refrigeration System:
Secop compressor:
Copper plate heat exchanger, which increases heat dissipation to the largest area;
Unique refrigeration technology, the temperature of the cold trap can be lowered from ambient temperature to below -80°C within 2 minutes;
Class A temperature sensor with high temperature accuracy and low error rate;
The multiple detection and alarm system can promptly alert when the refrigeration system pressure is too high or in case of refrigeration failure, and take corresponding measures.

Vacuum System:
High frequency Wide Range
Pirani Vacuum Sensor:
With automatic temperature compensation control unit, Pirani vacuum sensor is capable of precise detection low-temperature environments.

CKD High Vacuum Electromagnetic Control Valve:
Low heat generation, light noise and long-lasting durability.

Stainless Steel Flexible Vacuum Tube:
Will never aging and resistant to all types of corrosion.

Fully Automatic Pressure Relief and Drainage:
Completely eliminate damage to samples and sensors caused by unstable manual pressure relief airflow.
