2L Liquid Nitrogen Cold Traps


When used in line with a rotary vane or small diffusion pump, complete trapping of water vapor, solvents and other condensable gases is achieved, as well as a lower base vacuum.á These traps have also been used on diffusion pumping systems to minimize oil vapor migration from the roughing pump to the diffusion pump.á The primary use though, is as a fore line trap for getting condensable vapors out of the gas stream so they do not enter the vacuum pump and degrade the fore line pressure of the pump through contamination.

It is important when using these traps to maintain the level of the liquid nitrogen at the correct level in the trap.

The HyVac LN2 traps come with a number of nice features.á Demountable liquid nitrogen reservoir for easy cleaning, 3 point support brackets, NW16 option port, electro-polished ID and OD 304 stainless steel construction.  Trapping Temperature to -187 Degree F.

The 1 Liter Trap lasts roughly 12 hours.á The 2 Liter about 20 hrs when run at 0-50 micron.á Higher pressure operation decrease life span of LN2 charge.á These are provided as a rough rule of thumb and are not exact.
