Chemglass Schlenk Airfree Adapter Style B 15 mm O-Ring Joint 11 mm Barb Lot of 2

The Chemglass AF-0070-06 Schlenk Airfree Adapter, Style B, is a specialized piece of borosilicate glass laboratory apparatus designed for creating and maintaining an air-free or inert atmosphere in chemical reactions, particularly within Schlenk line setups. It features a 15 mm O-ring joint, which provides a secure, greaseless seal when used with a compatible #116 Viton O-ring (typically supplied with each adapter). The other end of the adapter has an 11 mm serrated hose connection, designed for attaching heavy-wall rubber vacuum tubing or similar flexible lines, enabling connection to a vacuum/inert gas manifold. These adapters are part of the AF-0070 series and are specifically intended for use with Chemglass AF-0060 through AF-0062 vacuum manifolds. The "Style B" designation indicates a specific configuration that allows the manifold to connect to standard glassware or tubing products.
