Product Description

At inlet pressures below 1 mbar cold traps using dry ice or liquid nitrogen as coolant provide important protection for your pump by separating condensates and aggressive media. Cold traps using liquid nitrogen may be essential with very volatile solvents and reduce the back streaming of oil molecules into the vacuum system. Furthermore a cold trap will considerably increase the effective pumping speed for vapors.
