Liquid Nitrogen Trap
Product Details:
LN2 is essentially a double walled container containing LN2 in the central chamber. The inner surface of the trap gets cooled when filled with LN2 and it condenses water vapour and other condensable, thus reducing the pressure by a large extent. With the LN2 trap, a ultimate vacuum of 1x10-6 mbar can be achieved. The LN2 trap is usually fitted above the diffusion pump.
