What is the function of rotary evaporator?
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 evaporation.
What does the rotary evaporator rotovap accomplish and how does it work?
A rotary evaporator, or “rotovap” in lab jargon, is an instrument used in a chemistry lab to remove a volatile solvent from a liquid mixture. In a cannabis setting, the most common use for it is to remove ethanol from a winterized extract. A rotovap works by creating a vacuum in a rotating glass flask.
What is the major advantage of using a rotary evaporator?
A rotary evaporator is used to remove a solvent from a flask without having to heat that flask to the boiling point of the solvent at one atmosphere. This has the advantage that it is quicker and is less likely to cause thermal decomposition to the sample. All the rotary evaporators are connected to a source of vacuum.
How do I choose a rotary evaporator?
Rotation speed range (rpm), vacuum (mm Hg), temperature, pressure (mbar) and condenser are key parts that should be considered when buying a Rotary Evaporator. You can decide on the type of Rotary Evaporator suitable for your application based on the size, type and sensitivity of the samples.
What are the advantages of a rotary evaporator versus a normal distillation set up?
The rotary evaporator utilizes a vacuum system wherein extracts could concentrated and solvents recovered at reduced temperature and pressure; local overheating is also avoided. This means that thermally labile compounds could be recovered in good yield and concentration time would be reduced too.
What is the function of a rotary evaporator?
Rotary evaporation parts and function: rotary flask is used to fill distilled material, electric motor drive flask to rotate; receiving flask is set to receive disposed distilled sample. Sealing ring is an important rotary evaporation part, sealing ring is the component to ensure high air-tightness of the instrument.
How does a vacuum pump work in an evaporator?
In the evaporation part, evaporation flask rotates in a constant speed to facilitate evaporation by enlarging evaporation area. 2. Vacuum pump removes gas from the sealed equipment to leave behind a partial vacuum, in order to create a continuous feed system and keep the purity of extracted solvents.
How big is a 50l rotatory evaporator flask?
The 50L rotatory evaporator is very spacious due to its high capacity. The evaporator kit is convenient with a 50-liter evaporation flask and a 20-liter collection flask. This makes the device effective and speedy in carrying out operations. The rotatory vacuum evaporator in the 50L rotavap gives heat to the bubble flask at a constant rate.
Why does the 50l rotavap have a glass condenser?
The rotatory vacuum evaporator in the 50L rotavap gives heat to the bubble flask at a constant rate. This ensures it rotates at a constant speed hence the fluid forms a large film on the sides of the jar. The 50L rotatory evaporator has a glass condenser that cools the soluble steam.
