What is Freeze Dryer ?

This device uses a solvent sublimation method to dry the heat sensitive materials. 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 material and the physical property  and chemical material of the material are preserved.

Freezer Laboratory  Model FD-5010-BT
It has a condenser drainage capacity of 10 liters per 24 hours and a temperature of -50C. The device consists of 3 trays for placing the product in bulk and vials, and 8 vacuum tubes for connecting balloons, flasks, falcon and erlon. From glasses The 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.

If a loose freezer device is used, the material can be frozen in a layer on the inside of the thermoset and then attached to the freezer duct using rubber valves. In this way, the ratio of the surface to volume will rise.
