Description
Chemglass Cold Addition Funnels, Airfree, Schlenk
Design:
- Constructed using grease-free 0 - 4 mm Chem-Vac™ Chem-Cap® valves on the pressure equalizing arm and lower inner joint
- Positioning of the valves permits the funnel contents to be kept under inert conditions prior to use or during loading
- 14/20 outer joint is sealed on the funnel body just above the coolant chamber for use with CG-3022 or CG-3024 septum stoppers for syringe sampling of the funnel contents
- Funnel has a drain tube on the rear of the coolant chamber
Features:
- Used in the preparation of block copolymers or any chemical synthesis requiring high vacuum techniques
- Has large diameter ring seal between the coolant container and the addition funnel body thereby reducing stress and permitting for use of a wide range of coolants, from ice-water to liquid nitrogen
- Open cup design of the coolant chamber allows for easy addition of coolant, particularly dry ice chunks, without "blow-back" associated with other funnel designs
