Aldrich^® air-sensitive chemistry glass lab kit 

Glassware with greaseless, threaded 14/20 joints require no clamps. The unique threaded nut with O-ring connectors in this system automatically separate ground-glass joints when unscrewed and reduces the chance of breakage. This glassware kit is compatible with Aldrich Schlenk-type glassware components which are specifically designed for air- and moisture-sensitive manipulations and reactions. Accessorize the basic glassware kit with Schlenk components to extend the range of applications to include drying and evaporation, extractions, filtrations, recrystallizations, washing degassing and more. Supplied in a foam-lined storage case. Thermoplastic screw caps with Viton O-rings usable to 140 deg C.
