What is Freeze Dryer ?

This device is used to dry the heat sensitive materials by solvent sublimation. In fact, in this method, the material is first frozen and then, by placing it inside the device and creating vacuum pressure by the solvent system, the solid phase is converted to the gas phase (sublimation), and eventually the substance remains dry. It should be noted that in this No thermal treatment is applied to the substance and the physical properties  and chemical material are maintained.

The FD-5005-HS-BT model

has a capacity of 5 liters of condenser dewatering for 24 hours and a temperature of -50 ° C. The device consists of 3 thermal trays for placing the product in bulk and a vial and 8 rubber vacuum valves for connecting balloons, flasks, falcon and erlon. From the glass Flask can be used to place the flask and vial. It should be noted that as the ratio to the volume of the material is greater, the drying time will be lower. The main difference between the model and the trays is the temperature, which can be high temperature precision The device can also be used for secondary drying using thermal trays. If a loose-freezer is used, the material can be frozen in a layer on the inner surface of the thermoset and then, using rubber valves, The freeze-drying device is connected. In this method, the surface-to-volume ratio will increase. Vacuum pump WOOSUNG Kerosene rubber vacuum cleaner Thermal Flask 600-300-150mm PLC Control Manifold 8-digit
