Rotovapped

It is often the case that a sample being rotovapped will “bump”, or send liquid upwards into the device. To prevent this, a bump trap is normally used. This blocks liquid from spouting directly upwards into the machine, but allows vapors to flow freely. Another necessary piece of glassware is an adapter, since all the

Jul 18, 2018 Poking your head around the chemistry lab it’s hard to not notice a deep purple solution being rotovapped in one area of the lab while a bright fluorescent blue column is being run in another area. But don’t get too hypnotized, or the next thing you know you’ll have spilled your bright green solution all over the floor.

Mar 13, 2016 (Apparently juicing pomegranates is not a fun task.) It was intensely flavorful, clean, and bright. I'm not sure what, exactly, they did, but it was amazing. That said, they didn't have anything on the menu that had been rotovapped, while most of the cocktails featured something that had been clarified in a centrifuge.

Nov 21, 2013 After drying the solution was rotovapped half way down until white crystals formed in solution. This was chilled to drop more crystals, and then filtered with a hirsch funnel and a ligroin rinse. The filtration yielded white shiny crystals which were dried between filter paper. A lot more crystals formed in the filtrate, but there were plenty ...

rotovapped off. The product was washed with a 50/50 water/chloroform mixture. Since product dissolves in chloroform, the chloroform layer was removed and rotovapped off. The remaining liquid was dried with magnesium sulfate, filtered, and all remaining solvent was evaporated off yielding 16.2 grams of yellow liquid.

rotovapped. The product was diluted with dichloromethane and washed with water (3 x 5 ml). The organic layer was dried over anhydrous sodium sulfate, and dichloromethane was removed. Silicagel chromatography with ethyl acetate:hexane (3:7) was used to purify and collect the crude product, pnitrophenol.

the three-necked ports. These solutions were rotovapped to dryness and redissolved in CDCl 3 for 1H and/or 13 C-NMR analysis. After NMR, the solutions were rotovapped again and redissolved in ~300 L THF (final concentration 3mg/mL) for injection onto the GPC system. 1H and 13 C NMR analyses were conducted on either a 400MHz or

The warmed reaction mixture was then poured into 10g of ice and mixed. The organic layer and aqueous layers were then separated and washed with NaOH then NaCl. Then drying the organic layer with magnesium sulfate to remove the excess water. Finally, the solution was filtered, rotovapped, and vacuum distilled to yield the final product.
