Refrigeration mode: compressor refrigeration, environmental protection refrigerant
The evaporation rate is affected by the absorbed energy and the speed of vacuum pump. The evaporation surface area of a sample is relatively large, rather than the volume and quantity of samples. Therefore, it is better to use a cold trap than to use a larger vacuum pump. On the one hand, the application of cold trap is helpful to condense steam, on the other hand, it can improve the evaporation density of organic solution for better condensation.
