During laboratory evaporation, the main function of the Cold Trap is to collect harmful vapors before they enter the vacuum pump. For a vacuum pump that requires oil, collection of solvent vapors is essential to prevent them from collecting in the vacuum pump’s oil. Also, if corrosive or water vapors collect in pump oil, the vacuum pump will be damaged and eventually the vacuum pump will cease beyond repair.
