Chemglass Life Sciences 150mL Funnel, Cold Addition, 24/40 Top Outer, 24/40 Lower Inner, 370mm OAL, Airfree, Schlenk
150mL Funnel, Cold Addition, 24/40 Top Outer, 24/40 Lower Inner, 370mm OAL, Airfree, Schlenk. Used in the preparation of block copolymers or any chemical synthesis requiring high vacuum techniques. Funnel features a large diameter ring seal between the coolant container & the addition funnel body. The open cup design of the coolant chamber allows for easy addition of coolant, particularly dry ice chunks. Constructed using grease-free 0-4mm Chem-Vac™ Chem-Cap valves on the pressure equalizing arm & lower inner joint. Positioning of the valves permits the funnel contents to be kept under inert conditions prior to use or during loading. A 14/20 outer joint is sealed on the funnel body above the coolant chamber for syringe sampling of the funnel contents. Funnel has a drain tube on the rear of the coolant chamber.
