Chemglass AF-0546-04 Airfree Schlenk filter tube with dual 14/20 inner standard taper joints, 30 mm OD coarse fritted disc, two side arms, and 2 mm high-vacuum glass stopcocks with stainless constant-pressure retaining devices for air-sensitive filtration, Schlenk-line work, inert atmosphere transfers, recrystallization, crystal collection, organometallic synthesis, catalyst isolation, precipitate washing, vacuum/inert gas manipulation, and specialty synthetic chemistry glassware setups. This double-ended filter tube allows filtration followed by collection of crystals/material on the opposite side of the fritted disc, making it useful for sealed filtration workflows where exposure to atmosphere needs to be minimized.
