WebbIn chemistry and other experimental sciences, septa are rubber stoppers which seal flasks or bottles. They are designed to be pierced by a needle or cannula which allows fluids to be transferred. Septa are often used together with Schlenk flasks and Schlenk lines to handle oxygen- or moisture-sensitive materials. Particle accelerators WebbThe resultant solution was placed into a round bottom flask along with a poly(GMA) PVDF polymer scaffold. The flask was then sealed with a rubber septum and heated to 90 °C in a sand bath atop a hot plate with temperature control (7 × 7 Hot/Stir Pro, 120 V, VWR), while being continuously mixed at 320 rpm for 72 hours.

WebbLarge rubber septa may be used to cap female joints. However, the use of 6-mm septa and 9-mm o.d./6-mm i.d. medium-wall glass septum inlets is preferred. The small rubber septum provides a more positive reseal after puncture and allows less rubber to be in contact with organic vapors in the reaction vessel. WebbThe protective top prevents accidental puncture of the septum and resulting sample loss. Can be stored down to -80°F.
