Aug 15, 2021 Some solvents/reagents are not really suitable for rotary evaporation, unless the exhaust from your vacuum pump is vented into a fumehood. Pyridine is one. Try extracting it out instead (dilute HCl will help), or remove in vacuo in your fume hood. The spermies of the males in your lab are susceptible to pyridine and you don't want an accidental ...

Dec 30, 2013 Standard solutions that are used for extraction are: 5 % hydrochloric acid, 5 % sodium hydroxide solution, saturated sodium bicarbonate solution (~6 %) and water. All of these solutions help to modify the (organic) compound and make it more water-soluble and therefore remove it from the organic layer. More concentrated solutions are rarely used ...

In a Graham-type condenser (the right condenser in the picture below), the water flows around a tube (whether straight or coiled) that contains the vapor/condensed liquid. ( picture source) The Graham-type condensers clog (or flood) more easily since they have a more restricted path for the liquid to return to the pot.

Install the receiving flask and evaporating flask on the rotary evaporator. After applying vacuum grease evenly on the grinding mouth, clamp it with a clamp. 6. Add appropriate amount of water to the water bath, turn on the power, set the heating temperature, and the heating indicator light is on, and it can be used normally. 7.

Jun 03, 2021 Hydrocephalus ex-vacuo: What is termed hydrocephalus ex-vacuo occurs when there is damage to the brain caused by stroke or injury, and there may be an actual shrinkage of brain substance. Although there is more CSF than usual, the CSF pressure itself is normal in hydrocephalus ex-vacuo. Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) …

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...

Oct 01, 1996 Pneumothorax ex vacuo is a little-known complication of lobar collapse. In this condition, acute bronchial obstruction from mucous plugs, aspirated foreign bodies, or malpositioned endotracheal tubes causes acute lobar collapse and a marked increase in negative intrapleural pressure around the collapsed lobe. As a result, gas is drawn into the pleural …
