The Schlenk line (also vacuum gas manifold) is a commonly used chemistry apparatus developed by Wilhelm Schlenk. It consists of a dual manifold with several ports. One manifold is connected to a source of purified inert gas, while the other is connected to a vacuum pump. The inert-gas line is vented through an oil bubbler, while solvent vapors and gaseous reaction products are preven… WebWhen frozen, open the Schlenk adapter to dynamic vacuum again for ten minutes. Repeat until thawing yields no bubbling (usually 3-4 cycles are sufficient). 6. After your last thaw, close off the vacuum and backfill the line with inert gas. Open the Schlenk adapter so that your flask is under a dynamic inflow of inert gas. If you’re taking WebI currently use a mix of kemtech/synthware and chemglass glassware. So far, I haven't notice any differences. I also have a kemtech schlenk line but haven't used it enough to give it a proper review. In the past, i have used both expensive schlenk lines (2000+) and cheap (300 USD), and i've only ever broken the expensive one. protein tyrosine phosphatase receptor type f
