Product features: 1. It can be used as a cooling water device for centrifugal concentration device CVE-1010 and small rotary evaporator SE-1000. 2. Using a low boiling point glass recovery container, the recovered gas passes through the condenser coil, so the low-temperature contact area increases and the recovery rate is improved. 3. Equipped with a simple vacuum controlled release device as standard, it can improve the recovery rate of organic solvents. 4. UT-500B adopts a water-cooled compressor, which will not cause confusion in the airflow inside the tank.
