Applications

Rotary evaporator is an important equipment used in chemical laboratories of pharmaceutical, chemical, biological products and other industries, It uses the principles of constant temperature heating and thin film evaporating to implement evaporating, concentrating, crystallization, drying, separation, solvent recovery and other operations under vacuum negative pressure condition.

Rotary evaporation is most often and conveniently applied to separate "low boiling" solvents which are solid at room temperature and pressure, It can remove of solvents from samples by evaporation with high efficient and gentle features.

KT rotary evaporator applies selected materials to guarantee working performance, Telflon+Viton vacuum sealing reduce the pressure leaking risks, high grade borosilicate glassware enhance the service lifespan significantly, PTFE valves eliminate the reaction or contamination with sample samples. Also water bath modular designing, make the equipment more flexible to replacing or upgrading, safety protection methods are very considerate to prevent the mis-operation conditions,such as dry running,over temperature and ground power failures.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.

FAQ

What is the purpose of a rotary evaporator?

The purpose of a rotary evaporator, or rotovap, is to distill a solvent to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation. The rotovap is used to concentrate non-volatile components in a mixture and to extract volatile aroma and flavor molecules from mixtures gently and at low temperatures. The two key components of the rotovap allow for a gentle, precise, and efficient distillation not found in conventional distilling apparatuses: vacuum removal of solvent to lower boiling point and rotary flask rotation to increase surface area and speed up distillation.

Why rotary evaporator is used in solvent extraction?

Rotary evaporators are used in solvent extraction because they allow for the efficient and gentle removal of solvents from samples by evaporation. This is achieved by reducing the pressure to lower the solvent boiling point, rotating the sample to increase the effective surface area, heating the solution, and then condensing the evaporated solvent in a cooled glass condenser. This process leaves the concentrated compound in the flask and is often used in medicinal chemistry, pharmaceutical, chromatography, and petrochemical fields.

Can rotary evaporator remove water?

Yes, a rotary evaporator can remove water. By changing the temperature to speed up the evaporation rate or by vacuuming with a vacuum pump to further reduce the pressure and lower the boiling point, a rotary evaporator can evaporate solutions that contain water and other substances. The electronic control of the rotary evaporator keeps the rotation of the flask at a constant speed, creating a larger surface area for heating and faster evaporation speeds. The traditional distillation method is less efficient and accurate than a rotary evaporator, which is widely used in chemical laboratories, industrial, bio-pharmaceutical, and food-making fields.

Is rotary evaporator used for distillation?

Yes, rotary evaporator is used for distillation. It is a device used in chemical laboratories to efficiently and gently remove solvents from samples by evaporation. The system works by reducing the pressure to lower the solvent boiling point, rotating the sample to increase the effective surface area, heating the solution, and then the evaporated solvent condenses in a cooled glass condenser. Rotary evaporation is most often and conveniently applied to separate "low boiling" solvents such as n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure.

What are the principles of rotary evaporation?

The basic principle of rotary evaporation is to increase a sample's surface area and optimize its temperature and vacuum level, enabling effective separation of solvents in a short time. A cooling condenser helps to recover the separated solvent. It is a gentle and efficient method for liquid separation and purification, with specific applications including concentration, crystallization, solvent distillation, and chemical synthesis. A rotary evaporator and a vacuum pump are the two equipment required for a rotary evaporation system. Selection of the optimal vacuum pump is based on considerations such as chemical compatibility, ability to process wet vapors, ultimate depth of vacuum, flow rate, and adjustable control of vacuum levels.

What are the advantages of a rotary evaporator?

The advantages of using a rotary evaporator include lower boiling temperatures, faster evaporation of solvents, fewer operations, and the ability to suppress bumping during the process. The lower boiling temperatures allow for the separation of solvents and compounds at lower temperatures, while faster evaporation speeds up the process. Fewer operations are needed thanks to the built-in lifting and falling motor, and bumping is suppressed, allowing for quick and gentle evaporation. Rotary evaporators are particularly useful for heat-sensitive compounds and distillation of complex mixtures.
