Apply to drying in laboratories such as cosmetics, fermentation broth, soil, materials, etc.
product description:
9kg-12kgs water capture capacity, which can meet the needs of laboratories with large freeze-drying requirements for water capture capacity
-70°C/-90°C ultra-low temperature cold trap, which can capture lower temperature organic solvents
Unique refrigeration technology, the cooling time of the cold trap from the start of the low-temperature refrigeration system to the target value is ≤3 minutes
Hemispherical cold trap bottom surface is more conducive to the discharge of condensed water
The cold trap and condenser coil are all Teflon anti-corrosion treatment, which can freeze-dry a large amount of ultra-low temperature organic solvents
One-click hot gas defrost, with defrost compressor protection program.
Large flat flange silicone seal, permanently no need to apply any auxiliary sealing silicone grease
High-precision ultra-wide width detection, vacuum sensor with full-range automatic temperature compensation, making vacuum display more accurate
The cavity vacuum can be read and controlled accurately, and the vacuum control accuracy is ≤0.1mbar
Removable sample shelf with dedicated holes for centrifuge tube placement, making placement and height adjustment easier
Configuration of various types of chambers and T-frames can fully satisfy users’ sample placement
Optional configuration of eutectic point detection system and data export system.
The vacuum pump and sample placement chamber can be combined at will according to user needs, making the configuration more flexible and convenient
