Cold trap(The cold trap is optional and can be customized to meet the customer’s needs)

The evaporation rate is influenced not only by the energyinputbut also by the pumping speed of the vacuum pump. The mainfactor affecting the efficiency of the vacuum pump is the largeevaporative surface area of the sample, rather than thesample quantity or volume. To reduce evaporation time, werecommend using a cold trap in conjunction with centrifugalconcentration.This not only helps in condensing water vaporbut also increases the vapor density of organic solventsmakingit easierforcondensation to occur.
