Nitrogen Cold Trap NW/KF16
This cold trap removes impurities such as air and moisture from helium gas circulating in a Kelvinox dilution refrigerator or other processes. In use, the trap is immersed in liquid nitrogen.
For continuous operation, two cold traps are maintained in liquid nitrogen and the used cold trap is removed for regeneration while the alternate trap continues the function. The open dewar, H3-110 is designed to accommodate two cold traps. 2 diameter NW/KF 16mm vacuum fittings
