Dec 18 2018nbsp018332A rotary evaporator or rotovap in lab jargon is an instrument used in a chemistry lab to remove a volatile solvent from a liquid mixtureIn a cannabis setting the most common use for it is to remove ethanol from a winterized extract.
Dec 20 2019nbsp018332A rotary evaporator rotovap or rotavap refers to a kind of equipment for solvent evaporation under reduced pressure which is composed of a vacuum system a heated water or oil bath a condenser and a motor that rotates the evaporation flaskThey cooperate with each other and all play an essential role in the working process of a rotary evaporator.
Dec 22 2020nbsp018332The easiest and quickest way to clean a rotary evaporator is to simply flush the machine with acetone or another solvent of your choiceWhile this is not the most thorough cleaning method it is ideal for situations where time is limitedTo flush a rotary evaporator with acetone fill up a small twoneck flask around halfway with acetone.
Feb 16 2019nbsp018332Filament tape applied in a crisscross pattern will help pieces stay together in case of an implosion or explosion meaning there’s less chance of glass shards injuring lab personnel and damaging nearby equipmentMesh or netting is often applied for a similar effectThis rotovap setup includes a taped collection flask.
Feb 21 2021nbsp018332Our allinone Hydrogen modern rotary evaporator sets a new standard for rotovaps and is changing the way people see rotovapsThis will ultimately become the standard rotovap in labs and industries worldwideI see a future where this selfcooling rotovap technology replaces all water dry ice and chiller rotovaps in the world.
Jan 18 2017nbsp018332When operating a rotovap following tips should be rememberedTo remove algae gunk from the inside of a coiled water condenser the condenser has to be removed from the rotovap and the coil is soaked in a dilute nitric acid solution for a few hoursAfter carefully rinsing the insides the rotovap is reassembled.
Jan 18 2018nbsp018332How and when to to clean rotovap glassware For glassware with difficulttoclean attachments the best idea is use suitable washing detergent to dissolve attachment before washingAnd for complex structure rotovap glassware such as condenser if a hairbrush doesn’t work use cleaning solution to immerse wash is a good solution.
Jul 08 2021nbsp018332Rotary evaporators commonly known as rotovaps rotavaps or rotavapors are extremely valuable to a number of downstream applications requiring efficient distillation amp solvent removalOften combined with a vacuum pump rotary evaporators are used to remove solvents from samples through evaporation.
Jul 21 2017nbsp018332Connect vacuum pump to cold trap and cold trap to rotovap vacuum portTurn on heat bath and set to 40176C 113176FOnce heat bath and coil have reached the desired temperature turn on rotovap motor and set speed to approximately 100 RPMStart vacuum pump and allow it to pull down for a few minutes before beginning injection.
Jun 06 2016nbsp018332slowly apply vacuum to your rotovap system by regulating the stopcock valve at the top of the rotovapIf the flask contents bubble vigorously you should cease applying direct vacuum to prevent bumping up into the system.
Jun 26 2019nbsp018332Thankfully there are several ways to make your rotary evaporator process faster Increasing the rotation speedIncreasing the bath temperatureWhile these methods all involve increasing certain parameters there are caveats in each case.

Rotovap is more efficient as compared to the short path because the rotovap runs in a vacuum environment that protects the extractor solventsThe short path on the other side is not very pure because it can transfer some extracted solvents along the way from the evaporation flask to the receiving flaskAdd Yard 26 Dongqing Street.
