Cold trap (also known as cold trap or condenser)It is a device that prevents vapor or liquid from entering the measuring instrument from the system, or from entering the system from the measuring instrument. It can provide a very low-temperature surface where molecules can condense and increase the vacuum degree by one to two orders of magnitude. A cold trap is a device that captures hydrazine gas by condensation on a cooled surface. It is a device placed between a vacuum container and a pump, used for adsorbing gas or capturing oil vapor.

The device that uses physical or chemical methods to reduce the partial pressure of harmful components in gas and steam mixtures is called hydrazine (or trap). Cold trap treatment is a cooling device used to collect substances within a certain melting point range. Place a U-shaped tube in the refrigerant, and when gas passes through the U-shaped tube, substances with high melting points become liquids, while substances with low melting points pass through the U-shaped tube to achieve separation.

Cold trap characteristics:

1. Adopting Hesi TFT-LCD true color display screen, with dual operation modes of touch screen buttons and physical buttons, while displaying set parameters and operating parameters.

2. The collection bin is made of sodium calcium glass material with good chemical resistance, and the cold storage capacity can reach 4L.

3. Adopting fluorine free refrigeration compressor unit and environmentally friendly refrigerant R404a, with a wide temperature control range: -40 ℃ - room temperature, and can be set during operation; Equipped with prefabricated cooling function, it can quickly cool down to the set temperature; Equipped with standby cooling function, it can be used in standby mode
Maintain the set temperature in the state.

4. Adopt a closed circulation method to avoid laboratory environmental pollution.

5. Split design, free assembly and matching, flexible and convenient.

6. Equipped with quick connectors and made of 304 stainless steel anti-corrosion material.

7. Cold traps can be used withVacuum centrifugal concentratorContinuous use.

8. Efficient solvent rapid capture system for condensing solvent vapors. When the cold trap condenses steam into liquid, the reduction of gaseous substances increases the vacuum degree of the system, thereby accelerating the concentration process and significantly improving the performance of the vacuum concentration system.
