What Is Cold Traps?

What is Cold Traps

A cold trap is a trap that traps gas by condensation on a cooled surface. Cold trap is device for adsorbing gases or capturing oil vapors and placed between the vacuum container and the pump.

Cold Traps is a device that prevents vapor or liquid from entering a measuring instrument from a system, or from a measuring instrument entering the system.

A cold trap is a cooling device used to collect substances within a certain melting point range.

What Are The Types Of Cold Traps?

Cold Traps Types

Depending on the cooling method of the cold traps, there are two types cold traps: Indirect Cooling Cold Traps and Direct Cooling Cold Traps.

Here we introduce them in details.

How Does Cold Traps Work?

How Does Cold Traps Work

The working principle of cold trap is that the negative pressure reduces the boiling point of the solvent, captures the evaporated gas, and makes the evaporation process proceed quickly.

Cold trap processing is a cooling device used to collect substances within a certain melting point range.

Cold trap plays a role of separation.

You can put a U-shaped tube in the refrigerant when the gas passes through the U-shaped tube.

The substance with high melting point becomes liquid and the substance with low melting point passes through the U-shaped tube.

The cold trap can be used in conjunction with the vacuum centrifugal concentrator.

The use of the cold trap is beneficial to the condensation of water vapor on the one hand.

It improves the evaporation density of the organic solvent, making it easier to condense.

How to Choose Cold Traps?

How to Choose Cold Traps

The cold trap is a device that captures moisture during the freeze-drying process.

Here is the tips on choosing cold traps for specific purpose.

Your material

Look:

If your object material need to freeze-dry at -50°C, a general direct or indirect cold trap is suitable.

However, if it needs -80°C temperature to freeze, a CT-80 Direct Cooling Cold Traps will be a better option for your goal.

To sum up, a CT-80 cold trap will be a good choice both for ordianry and special temperature materials.
