As you well know rotary evaporators have a lot of different glass componentsMost of those components connect to each other by ground glass joints but glass joints come in many different sizes and styles and many people arent aware of the glass joint sizing nomenclature and what it means so we wanted to explain it to you.

Aug 10 2018nbsp018332Extraction technology has evolved and changed the way we consume cannabisThe rotary evaporator plays an integral role in the extraction process because it efficiently removes extraction solvents by evaporation without harming the productTypically the rotary evaporator rotovapis used in postextraction refinement or recovery after ethanol extraction.

Aug 15 2019nbsp018332The rotary evaporator can be even used in people’s daily life as wellIt is adopted to concentrate fruit juices or food very often in order to get a better taste and smoother juicesUnder the action of vacuum and high temperature the boiling point of fruit juices is around 5060176C which is much lower than that under normal pressure and.

Rotary Evaporator Replacement Glassware.

Aug 20 2021nbsp018332A rotary evaporator is a laboratory device used for the removal or recovery of solvents at low pressureAs its name indicates it evaporates substances through the process of distillation to later be condensed and later its components separated one by oneThese equipment have existed in laboratories around the world since the 1960s when the.

Bump Trap 250mL Rotary Evaporator Modified 2440 Top Outer 1420 Lower InnerSimilar to CG1320 but with the addition of two 4mm drain holes at the base of the inner tube to allow solvent to drain back into the evaporation flaskTraps have a 2440 top outer joint and the listed size of lower inner joint.

Dec 22 2020nbsp018332To flush a rotary evaporator with acetone fill up a small twoneck flask around halfway with acetoneThen connect one socket of the flask to the rotary evaporator where the evaporation flask is typically locatedEither hold the flask by hand or secure it to the machineTo close the second socket of the twoneck flask hold your thumb over it.

Feb 14 2022nbsp018332Rotary evaporators work on the principle that solvents have a range of boiling points which decrease under reduced pressureThe evaporation flask rotates at a specified speed forcing the materials to form a large area of thin film on the inner wall of the flaskThe flask is heated evenly and materials with a lower boiling point rapidly evaporate.

Feb 25 2021nbsp018332Evaporation is a gentle efficient way to remove solvents and the process of rotary evaporation is a reducedpressure distillationIt involves placing a sample within a roundbottomed flask which is then placed in the rotovap’s heated water bath and rotatedA vacuum pump reduces the pressure above the solvent.

Hold the flask in place with your hand5 Turn on the vacuum with the check valve near the sink6 Close the stopcock at the top of the rotary evaporator condenser7 While you are still holding the flask turn the dial for the rotary evaporator motor to rotate the flask slowly at first then at a higher speed so that foaming of the solvent is kept at a safe limit.

If a mechanical pump is used instead of an aspirator to produce a vacuum a secondary trap has to be used to prevent that the solvent destroys the membrane or is absorbed in the oil.

In close cooperation with users we developed the HeiVAP series of rotary evaporators with an emphasis on the essentials well thoughtout details with a focus on features and functions to facilitate everyday laboratory workVersatile combinations with glassware and extensive accessories offer the right configuration for every application.

Jan 01 2020nbsp018332Rotary evaporation is a powerful technique for quickly removing solvent from a solution of cannabis or hemp extractThere are two distinct methods of operating a rotary evaporator batch or continuous choosing the correct one for the task is crucialFor the purposes typically required in the cannabis industry i.

Mar 01 2021nbsp018332The rotary evaporator will then heat up the solution to speed up the process of evaporation even moreAs previously stated decreasing the pressure of the system significantly lowers the boiling point of the solutionAs such far less heat is needed to evaporate a solution using a rotary evaporator than a system that remains at atmospheric.

Nov 04 2021nbsp018332How is a rotary evaporator made This equipment consists of an electric motor that causes the rotation of a tube attached to a ground glass joint guide tubeThe latter has attached to its structure a round bottom flask containing the solutionMaintaining a rotary motion this flask is partially immersed in the water.

What are Rotary Evaporators A rotary evaporator also called as rotavap or rotovap is a device used in labs for the efficient and gentle removal of solvents from samples by evaporationThe picture on the right shows what a typical rotary evaporator includes.
