USA Best Seller 2019 New Designed -40 Degree Stainless steel Bath Cold Trap CT-40x with Stainless Steel Trap

Cold trap is used to capture water vapor and harmful gases emission from vacuum drying oven and pressure reduced concentration
device, improving efficiency of vacuum system, extending life-span of vacuum pump.

* It can be used in drying system for capacitor, battery pole and battery cell.
* It also can be used as pre-freezing bath and low temperature bath.
* Digital display for batter control of the bath temperature, which makes it easier to start the vacuum pump at right time.
* Stainless steel 304 liquid bath can be used to do water or ethanol cooling experiments. If equipped with glass condenser, it
also can be used to deal with acid or organic solvents.
* Designed with drain valve for easy discharge of collected liquid.

Specifications of Zhengzhou Greatwall 2019 New Designed -40℃ Cold Trap CT-40x

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.
