Cold trap is a device that condenses gas on a cooled surface and is placed between a vacuum container and a pump. To prevent vapors being evacuated from an experiment from entering a vacuum pump.In organic experiments, the application of cold hydrazine is used as a device for adsorbing gas or capturing oil vapor.
