nbsp As we known cannabis contains 80 types of actives compounds that are only found in cannabis which known as cannabinoidsCBD and THC are the main components in cannabis how to draw out the components Simply to use a rotary evaporatorWhen applying a rotary evaporator for cannabis extractionnbspsolvents is the key material that make the whole chemical reaction possibleIn last post we talked about how to extract cannabis by a rotary evaporator we’ve mentioned that ethanol is used as the solvents for cannabis extraction.
Use the dial on the rotary evaporator control panel to set the desired spin speed of the condenserIf the desired evaporation should be timed press the timer button on the rotary evaporator control panel and use the dial to set a time in minutes or press the int button and use the dial to set a time in seconds.
Tasks with the rotavap must only be performed when operation is monitored.
Use a bump bulb see picture placed between your sample and the condenser to prevent contamination of the condenser area and your sample in the event of bumping.
Apr 01 2010nbsp018332The dial on the motor is used for speed control of the flask rotationA typical rotavap uses a variable speed sparkless induction motor that spins at 0220 rpm and provides high constant torqueThe aspirator vacuum is turned on.
Apr 21 2018nbsp018332Ethanol is considered as the most effective and safest cannabis extraction solventsBasically there are 3 steps extract the desirable winterize the concentrate and distill the concentrationA rotary evaporator or other vacuum distillation instruments is used at this time to remove ethanolIf you choose cryogenic ethanol instead of warm.
Aug 10 2018nbsp018332Buchi provides traditional rotovap systemsbut specializes in small precision batchesSince the extraction process is already complex Buchi strives to design easytouse technologyThe business is familyowned and operates globally with a network of support centers 16 subsidiaries and more than 70 distribution partners.
Aug 15 2021nbsp018332Use common sense when selecting a temperature unless you lack common sense or are crippled with self doubtIn such a case a manometer and distillation nomograph can be utilizedFire up your rotovap with the vacuum open and slowly open the stopcock to allow it to pull solution from your Erlenmeyer into your bump trap.
Dec 20 2019nbsp018332R1050 Rotary Evaporator Using Methods of a Rotary Evaporator Only when rotary evaporators are used properly can they play greater role and function in many fieldsThere are some instructions that can be followed in order to use rotary evaporators better and more properlyConnect the hose to the condenser tap.
Jan 01 2015nbsp018332Ok so we know that with apparatus such as a rotovap using vacuum and heat one can relatively selectively boil off terpenes thus fractionally distilling a concentrateWhat say we flip this upside downWe go to cryo temps of 170f hypothetically locking up all most compounds then each.
Jul 08 2021nbsp018332Different Sizes From 2L To 50LOther than removing the solvents this equipment can also be used for the removal of moleculesThis evaporator equipment of 2L works.
Jul 21 2017nbsp018332For best results a chemicalresistant oilless diaphragm pump should be used with your rotovapThese pumps don’t have as much depth as rotary vane oil pumps but they are much more resistant to contaminationDon’t use an oil pump with a rotovap or you’ll find it destroyed in no time.
Jun 06 2016nbsp018332Before using the rotovap operator should be familiar with the various rotovap components and definitionsFirst take your sample solution in round bottom flask—volume half full to the rotovap you wish to use.
Mar 11 2019nbsp018332Researchers know that this orthodox evaporation method using a rotovap can take a very long time and is a large bottleneck in the overall synthesis and recovery processVacuum Vortex Evaporation takes a novel approach in evaporation by using rapid spiral air flow combined with heat to volatilize and quickly evaporate solvents even the most.
Mar 14 2019nbsp018332How to Use an Essential Oil Extractor It is convenient and simple to use an essential oil extractorFor example a glass essential oil extractor extracts essential oil and pure dew by distillation applicable for the common and isolated distillation and extraction process of plant branches leaves flowers and grasses with high oil and fats.
Mar 26 2019nbsp018332How to use a rotovapFirstly ensure the receiving flask is emptyTo empty the flask carefully remove the clip and pour any solvent into the appropriate waste bottleCarefully attached the receiving flask and secure with the clip.
On the rotovap motor and the speed control knob below itYou need not set the rotation speed of the flask at maximum however you must rotate the flask to prevent bumping at reduced pressureLower the entire condensermotorflask assembly into the heated water bath using the handle as shown at the right.

Rota evaporator or rotavap the essential lab instruments for distillation evaporation extraction of samplesBefore operating the rotavap you must carefully read the following safety instructions.
Rotovap registered trade mark lab science plant oil extraction Rotovapur is a unique company we design and invent new lab technology and rotary evaporator machines glassware lab apparatus for plant science extractions based on 30 years working in Terpenes and alkoloidsNature forming crystalline cryofreezing.
Sep 17 2020nbsp018332Rotovap’s Use In CocktailsThe rotovap has a large number of applications in cocktails but essentially it’s used either to add flavor or to remove undesirable characteristics of an ingredientThis machine is excellent at capturing and preserving the aroma of spices herbs and other ingredients but really specifically with the fresh.
Sep 23 2019nbsp018332Diaphragm pumps are dry pumps meaning they are oilfreeWe’ll discuss this further below but oilless pumps are generally better for rotovap applicationsOne major benefit of oilfree pumps is they require very little maintenanceThey tend to cost more upfront but you can save time and money in the long run.
The benefit to using a rotovap over a simple distillation system is that the rotation of the evaporating flask combined with a heated water bath increases the surface area of the productThis makes the distillation go faster and keeps the mixture evenly mixed and heated to promote a stable and even evaporation.
We use the rotovap for two main purposes 1 to concentrate nonvolatile components in a mixture for example concentrating the purest and freshest flavors from a blood orange by removing the water and 2 to extract the volatile aroma and flavor molecules from mixtures gently and at low temperatures for example extracting the desired.
