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. Take oneA U-shaped tube is placed in a 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.

Hesi Low TemperatureCold trap CT-50 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 sealed wide mouth collection bottle is made of sodium calcium glass material with good chemical resistance, and the capacity is optional.

3.Adopting imported fluorine free refrigeration compressor units and environmentally friendly refrigerantsR404a， Has a wide temperature control range: -50 ℃ - 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 maintain the set temperature in standby mode.

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

5.Small in size, only0.8m ³, with a collection area of 760cm ². High recycling efficiency, with a maximum capture capacity of 284mL/6H (anhydrous ethanol).

6.low temperatureCold trap can be used withVacuum centrifugal concentrationsystemContinuous use.

7. 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.
