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. 

* Material: Made from borosilicate glass, resistant to various chemical reagents, low thermal expansion, high pressure and temperature resistant, and highly durable 

* High Transparency: Features excellent transparency, allowing easy observation of the internal process and convenient monitoring of the experiment 

* Detachable Middle Component: The cold trap is designed to be detachable. This feature allows for easy cleaning and maintenance. Users can quickly disassemble the component to remove any residue or contaminants.
