Vacuum Desiccator UI-FT250
Vacuum Desiccator is used for pretreatment of wet felt and wet samples for veslic rubbing color fastness test, and sample pretreatment for leather shrinkage temperature test.
Principle: The air in the drying tank is extracted by a vacuum pump. After the vacuum pressure in the drying tank reaches the requirement, the vacuum pump is turned off and the sealed drying tank maintains the vacuum pressure state for a certain period of time.
Sample pretreatment: Put the water cup with the sample in the drying tank, start the vacuum pump, and generate a vacuum of 5kpa in the tank, keep it for about 2 minutes, and restore the normal pressure. Repeat the operation twice.
