WebThis dual Schlenk line provides three ports each of vacuum and nitrogen. Its main use is in providing oxygen free conditions for free radical polymerizations. It also allows vacuum distillation for the purification of reagents. Vacuum is provided by an Edwards RV12 pump, an Edwards diffusion pump, and a liquid nitrogen trap, providing base ... WebStep 1: Ensure that all Schlenk flasks and vessels connected to the Schlenk line are under inert gas and that all other stopcocks and taps are closed if not in use. Step …
WebHigh vacuum and Schlenk lines contain such manifolds and can aid in most air-sensitive techniques. There are three major differences between a high vacuum and Schlenk line: (i) Ground-glass and/or O-ring joints are used to connect reaction vessels on a high vacuum line whereas flexible tubing is typically used on a Schlenk line. 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.
Web15 jan. 2024 · With Schlenk Line. To set up a reaction with inert atmosphere, a Schlenk line with preset adaptors connected to gas lines could conveniently supply inert gas to clear the empty flask of any non-inert gasses. To purge a reaction solvent, the freeze-pump-thaw method could be performed using the Schlenk line’s vac and back cycle. Web29 dec. 2012 · For many reactions in this course, the reaction vessel will be a Schlenk flask. It consists of a pear-shaped or a round-bottomed flask, which has a sidearm near the top to connect it to the vacuum/inert gas line. If you conduct experiments under inert gas, the glassware has to be appropriately prepared by flame-drying the equipment under vacuum ...
WebA Schlenk filter, consists of sintered glass funnel fitted with joints and stopcocks. By fitting the pre-dried funnel and receiving flask to the reaction flask against a flow of nitrogen, carefully inverting the set-up, and turning on the vacuum appropriately, the filtration may be accomplished with minimal exposure to air.
