Rotary evaporator is a widely used equipment in laboratories, mainly used for distillation, concentration and purification of samples. Its working principle is to heat the sample and rotate it under low pressure to evaporate the solvent, leaving a concentrated sample. This equipment can effectively reduce the time and effort required for sample preparation and can handle samples of various specifications and types.
Rotary evaporator has a wide range of applications, including but not limited to the following areas:
Sample purification: Removing solvents from liquid samples through the evaporation process makes the purification process more efficient and accurate.
Solvent recovery: Recovering solvents from liquid samples and then using them again, saving time and cost.
Natural product extraction: Efficient extraction of natural products from plants and other natural resources.
Complex mixture distillation: Distilling complex mixtures into individual components facilitates analysis and understanding of the composition of the mixture.
Cannabis extract production: Plays an important role in the extraction of cannabinoids and terpenoids.
Pharmaceutical industry: Extraction of active ingredients, preparation of samples for analysis, compound purification, quality control and formulation development.
Chemical industry: Solvent recovery, distillation, sample concentration, solvent separation and essential oil production.
Food and beverage industry: concentrate flavors and fragrances, purify extracts, remove solvents from extracts, and analyze food and beverage samples.
The structure of the rotary evaporator mainly includes a rotary bottle, a condenser, a vacuum pump, and a heater. The rotary bottle is usually a round-bottom bottle with a stopper and a connecting pipe on the bottle mouth. The condenser is used to condense the evaporated solvent vapor, the vacuum pump creates a negative pressure environment, and the heater provides a heat source to evaporate the solvent quickly.
The working principle of the rotary evaporator is mainly to separate the liquid into multiple media by rotation. The process is to form a volume change in the oscillation cavity, and then separate the liquid. The separated substances can be used to replace the components in the liquid and obtain the separation effect of multiple media.
The advantages of the rotary evaporator include fine separation ability, energy saving, low noise, low pollution, etc., making the evaporation and separation of various liquids simpler and faster.
In the field of food and agriculture, the rotary evaporator can be used to extract the active ingredients in plant extracts, evaporating a large amount of extracted liquid into a small volume of extract for subsequent analysis and research.
Rotary evaporators are highly respected in the chemical, pharmaceutical, food and other industries for their efficient and rapid evaporation and purification functions. Its working principle is based on constant temperature heating and efficient evaporation under vacuum negative pressure. The high-speed rotation of the rotary evaporation bottle makes the solution form a thin film on the bottle wall, increasing the evaporation area and improving the evaporation efficiency.
