Labconco Liquid Nitrogen Secondary Trap

Labconco For processing samples with ultra low eutectic points. Secondary trap connects in series with a freeze dry system and vacuum pump to prevent contaminants from migrating into the vacuum pump. After pulling a vacuum, liquid nitrogen may be introduced via the liquid nitrogen port. Liquid nitrogen cools to -196°c (-321°f) to trap contaminants with low eutectic points. The well may be defrosted and the liquid drained from the drain hose. Glacier white epoxy-coated steel construction. Two valves may be opened (trap) or closed (by-pass). Opened valves allow gaseous contaminants to be trapped in the liquid nitrogen well. Closed valves allow gaseous contaminants to by-pass the well during defrosting and draining. ³/₄ in. O.d. Inlet and outlet connections. Includes an insulated filler tube for connection to a user-supplied liquid nitrogen tank; 20 in. Rubber tubing; ³/₄ in. I.d. X ³/₈ in. Wall; and two clamps. Liquid nitrogen is required (not included).
