The uses and applications of rotary evaporator, and the using steps of rotary evaporator.

What is the primary advantage of using a rotary evaporator over distillation

When should one use a rotary evaporator or distillation in an experiment? Many people think that evaporation and distillation are the same, but actually there are some differences between evaporation and distillation. For example, evaporation can be more accurate than distillation. Besides, evaporation has a higher efficiency, which means evaporation can save you more time. […]

What are the advantages of rotary evaporator

  Rotary evaporator is a very popular separation equipment, which is widely used in many fields. Rotary evaporator is so popular because it has many advantages, for example: 1. Rotary evaporator has a built-in lifting and falling motor. This device can automatically raise the rotary bottle to a position above the water bath when there […]

What are the rotary evaporator applications

Rotary evaporator is an indispensable instrument and equipment for the processes of evaporation, concentration, crystallization, drying, separation, and solvent recovery during the scientific research and production processes in the pharmaceutical, chemical and biological products industries. Rotary evaporator is mainly used for continuous distillation of large amounts of volatile solvents under reduced pressure. The applications of […]

How rotary evaporator works

The working process of rotary evaporator is a consecutive process under a reduced environment. There are several steps here: 1. Under reduced pressure, the evaporation flask was continuously rotated while the solvent was being distilled. The evaporation flask is a pear-shaped or round-bottomed flask with a standard ground mouth connection. It is connected with the […]

Rotary evaporator structure and functions

What is the function of rotary evaporator Rotary evaporator is called rotavap by people , which is an efficient separation equipment, which separates substances from mixtures by getting them evaporated and condensed. Rotary evaporator is widely used in many fields such as industrial field, chemical labs, food-making at daily kitchen, textile field and other fields. […]

The role that cold trap plays in rotary evaporator equipment

The function of cold trap A cold trap is a device that prevents vapor or liquid from entering the measuring instrument from the system or from the measuring instrument into the system. Generally, the cold trap is used to prevent oil vapor from returning to the application equipment in the vacuum environment, which can cause […]

Why rotary evaporator distillation is more widely used

Why rotary evaporator distillation is more widely used Rotary evaporator becomes more and more popular since it was invented. Because it dose have several advantages better than other distillation equipment, the contrast is as follows: Speed -the rotary evaporator distillation is faster. The rotary evaporator is electronically controlled to rotate the flask at a constant speed, […]

Rotary evaporator for extraction

Rotary evaporator for extraction There are all kinds of extraction equipment in many fields, for example, closed loop extractor, falling film evaporator, rotary evaporator, wiped film evaporator and so on. All these extraction equipment are to extract substances from mixtures efficiently, but their structures are different. Rotary evaporator is one of the most efficient extraction equipment, […]

Rotary evaporator extraction method

Rotary evaporator extraction method Rotary evaporator extracts and concentrates substances from mixtures by heating and evaporating sample materials according to the different boiling points of substances within mixtures. The basic principle of a rotary evaporator is the vacuum distillation of the distillation flask under continuous rotation. Many people still wonder the very specific details of rotary […]
