 PRODUCT FEATURES  


Cold trap is a small-sized ultra low temperature cryogenic equipment,suitable for Parylene vacuum coated cold trap, biochemical petroleum experiment, low temperature liquid bath, gas trap, drug freeze-drying and so on. There are two types of cold traps according to their applicaton method: pot type cold trap and bar type cold trap. The size of the cold trap, refrigeration mode can be customized according to the needs of the users.


Utilize compressor refrigeration to make the temperature in the pot chamber drop below -95, ( this temperature can be adjusted according to the actual application). Under low temperature condition, when the gas passes through the pot chamber, partial high condensation point compositions will be turned into liquid or even solid and stored in the pot chamber, the low condensation point compositions will continue to flow through the pipelines, so as to achieve the purpose of gas composition separation.


In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases into a liquid or solid. The most common objective is to prevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense and contaminate it. Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying.

 

Pumps that use oil either as their working fluid (diffusion pumps), or as their lubricant (mechanical rotary pumps), are often the sources of contamination in vacuum systems. Placing a cold trap at the mouth of such a pump greatly lowers the risk that oil vapors will back stream into the cavity.

 

Care should be taken when using a cold trap not to condense liquid oxygen (a light blue liquid) into the cold trap. Liquid oxygen is potentially explosive, and this is especially true if the trap has been used to trap solvent. Liquid oxygen can be condensed into a cold trap if a pump has sucked air through the trap when the trap is very cold.
