This two-piece trap with #15 O-ring joints on both the inlet and outlet ports is ideal for connection to most vacuum and Schlenk lines. The seal between the trap stopper and body is made with a 57 mm flat O-ring joint for grease-free operation. The lower trap body is 57 mm O.D. x 300 mm long, to be used with a 4.3 L Dewar flask. The complete item includes the trap stopper and body, one CG-139-02 horseshoe clamp, one CG-305-331 #331 Viton® O-ring and two CG-305-116 #116 Viton® O-rings. The overall assembled height of this item is approximately 440 mm.
Replacement glass components are also sold separately. We generally recommend purchasing a spare lower trap body with this complete unit for two reasons: 1) if you are working and need to clean out the trap, it will greatly reduce your down time as you can swap on a clean, room temperature, trap and 2) it's not uncommon to break the lower trap body at some point and you don't want to have your line out of commission while you wait on a replacement.
This item requires two CG-150-05 clamps (sold separately) for the O-ring connectors.
