Description
Technical Parameters
Rotovap cost and rotavap are both names for rotary evaporators, so they are actually different names for the same instrument.
The main purpose of Rotovap is to continuously distill large amounts of volatile solvents under reduced pressure conditions, suitable for concentration of extraction liquids and distillation of receiving liquids during chromatographic separation. It increases the solvent surface area through mechanical rotation, promotes evaporation, and reduces the risk of solvents.
At the same time, vacuum conditions lower the boiling point of the solvent, providing a means of separating solvents from compounds of interest. The following article will first explain the auxiliary equipment vacuum pump that provides a rotovap vacuum environment, and then compare the centrifuge and vacuum drying oven that have similar separation and concentration functions to rotovap.
We provide rotary evaporator, please refer to the following website for detailed specifications and product information.

Auxiliary equipment: Vacuum Pump
There are significant differences between rotovap and vacuum pumps in terms of function, purpose, and actual operation.
● Function
It is mainly used for separating and purifying substances. Through mechanical rotation and heating, organic and inorganic substances, fine chemicals, natural products, etc. in the solution can be separated and purified. The vacuum pump is responsible for providing a vacuum environment, thereby reducing the pressure during the evaporation process, accelerating the diffusion rate of gaseous substances, and reducing the interaction between the gas and liquid phases.
● Usage
It is widely used in laboratories in industries such as chemistry, pharmaceuticals, and food, mainly for separating and purifying substances in solutions. Vacuum pumps are commonly used in various situations that require reducing air pressure to improve work efficiency or reduce gas-liquid interaction, such as chemical reaction kettles, drying boxes, and other equipment.
● Actual operation
When operating the product, the distillation flask needs to be placed in a water bath for heating, and the pressure is lowered through a vacuum pump to accelerate the evaporation and diffusion of the solvent. The vacuum pump needs to adjust the vacuum degree according to actual needs during operation to achieve different working effects.
In summary, rotovap cost are mainly used for material separation and purification, while vacuum pumps are mainly used to provide a vacuum environment to achieve specific working effects.
Rotovap vs. Centrifuges
Rotovap and centrifuges are commonly used equipment in laboratories, and their differences are as follows:
● Function and principle
It is mainly used for sample concentration and drying treatment, and its concentration effect is achieved through heating, vacuum pump and other equipment.
● Application scope
It is mainly used in industries such as chemistry and pharmaceuticals, while the centrifuge is widely used in industries such as biology, pharmaceuticals, and chemical engineering.
● Separation effect
It can separate small molecular weight chemicals, while the centrifuge can separate biological macromolecules such as cells, enzymes, and polymers.
● Separation speed
It are usually slower than centrifuges and require long-term evaporation, while centrifuges can complete the separation of substances in a shorter period of time.
In summary, there are significant differences between rotovap cost and centrifuges in terms of function, principle, application range, separation effect, and separation speed. The specific choice of equipment to use depends on the experimental needs and objectives.
Rotovap vs. Vacuum drying oven
The rotovap and vacuum drying oven are commonly used equipment in the laboratory, and their differences are as follows:
● Function and principle
It is mainly used for sample concentration and drying treatment, and its concentration effect is achieved through heating, vacuum pump and other equipment. The vacuum drying oven is designed for drying samples and can be dried under a certain degree of vacuum.
● Drying effect
The drying effect of the rotary evaporator mainly depends on the properties and drying conditions of the sample, while the drying effect of the vacuum drying box mainly depends on parameters such as vacuum degree and temperature.
● Application scope
It is mainly used in industries such as chemistry and pharmaceuticals, while the vacuum drying oven is widely used in various fields that require drying samples, such as biology, pharmaceuticals, chemical industry, etc.
● Operation method
It is relatively simple to operate, usually just put the sample into the equipment and set the parameters. The operation of vacuum drying boxes is relatively complex, requiring different operations based on different samples and drying requirements.
Rotating evaporators, vacuum pumps, centrifuges, and vacuum drying ovens are commonly used equipment in laboratories, each with different functions and characteristics. It is mainly used for sample concentration and drying treatment, and its concentration effect is achieved through heating, vacuum pump and other equipment, while the centrifuge is mainly used for separating the sample, which is layered and separated by centrifugal force.
This indispensable instrument in modern chemistry laboratories can be traced back to the exploration of distillation technology in ancient times. After centuries of evolution, it ultimately formed the rotary evaporator as we know it today.
As early as the ancient Greek era, the great philosopher and scientist Aristotle conducted in-depth research on the principles of distillation and condensation. He discovered the laws of water circulation in nature by observing the evaporation and condensation processes of water, and proposed the theory that "by distillation, water can be first turned into steam and then into liquid, which can turn seawater into drinkable water.". This discovery laid the theoretical foundation for the later development of distillation technology.
Over time, distillation technology has gradually developed and improved. In the 2nd century AD, alchemists began to develop the earliest copper distillation device - the "distillation pot", which enabled distillation technology to be applied in practical production. However, during this period, distillation equipment still faced problems such as low efficiency and complex operation, making it difficult to meet the needs of scientific research.
In the 17th century, Irish physicist Robert Boyle conducted his first revolutionary vacuum distillation experiment. He proved the relationship between pressure and boiling point, which greatly improved the distillation speed. This discovery provides new ideas and methods for the further development of distillation technology.
In the 20th century, with the rapid development of science and technology, distillation technology has also ushered in new breakthroughs. Scientist C C. Draig and M E. Volk proposed the concept of rotating flasks to improve mixing efficiency and heat input efficiency. They believe that by heating the flask during rotation, the sample can achieve better mixing and larger heating area, thereby improving distillation efficiency. The proposal of this idea laid the technical foundation for the invention of the rotary evaporator.
In this context, Swiss chemist Walter B ü chi began the development of rotary evaporators. He adopted C C. Draig and M E. Volk's idea, combined with Basel's chemical industry, led to the research and manufacture of the first rotary evaporator. This instrument adopts a design of feeding tube and plug valve, allowing for continuous addition of liquid during distillation. At the same time, it also adopts a water bath heating method, allowing the rotating flask to be partially immersed in the water bath, thereby achieving uniform heating. This innovative design greatly improves distillation efficiency, making rotary evaporators widely used in laboratories.
Since the first rotary evaporator was introduced in 1957, this instrument has been continuously improved and perfected. With the development of technology, intelligent rotary distillation has become a standard configuration in modern laboratories. Modern rotary evaporators not only have the characteristics of high efficiency and automation, but also have various safety protection functions, such as overheating protection, overvoltage protection, etc., making experimental operations safer and more reliable.
Looking back at the discovery history of the rotovap cost, we can see that its birth was the result of scientific exploration, technological innovation, and industrial development. Its development process not only demonstrates the continuous exploration and improvement of distillation technology by humans, but also reflects the enormous driving role of science and technology in the development of modern society.
