Labconco® Vacuum Pump Traps and Accessories

Chemical Traps and Accessories for Rotary Vane Vacuum Pumps

Chemical Traps and Accessories For CentriVap®, RapidVap® and Precise®

Dry Ice Secondary Traps

For processing samples with low eutectic points. Trap connects in series with a freeze dry system and vacuum pump to prevent contaminants from migrating into the vacuum pump. An insulated well, when dry ice and solvent are added, cools to approximately -75°C (-103°F). When used alone, Dry Ice Secondary Traps may serve as an inexpensive collector. Simply connect a sample directly to the incoming port and add a vacuum pump to the outgoing port. Dry ice and solvent, such as alcohol, are required (not included).

Liquid Nitrogen Secondary Trap

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" OD inlet and outlet connections. Includes an insulated filler tube for connection to a user-supplied liquid nitrogen tank; 20" rubber tubing; 3/4" ID x 3/8" wall; and two clamps. Liquid nitrogen is required (not included).

Other Accessories

Bleed Valve allows the user to manually bleed air into a system such as the Dry Ice Freeze Dry System or Cold Trap attached to a CentriVap® Concentrator to break the vacuum.

Replacement Alumina Oil Filter For Chemical-Resistant Pumps neutralizes acid in the pump oil to help protect the pump.

Replacement Oil Mist Exhaust Filter for General Purpose and Chemical-Resistant Pumps removes oil mist from the pump exhaust. Ducting to outside not required. Includes filter assembly and one oil mist filter cartridge. Life is approximately one year at 1.33 x 10-2 mBar (10 microns) vacuum.

Vacuum Tubing Kit consists of tubing and clamps for CentriVap® and RapidVap® systems.
