Rotary evaporator for laboratory

Recently, many people are asking about rotary evaporators used in laboratories. In fact, there are many types of rotary evaporators. Let’s first look at the definition of rotary evaporators. Rotary evaporators are also called rotary evaporators and are commonly used in laboratories. The equipment consists of motors, distillation flasks, heating pots, condenser tubes, etc. It is mainly used for continuous distillation of volatile solvents under reduced pressure, and is used in chemistry, chemical engineering, biomedicine and other fields.

Recently, many people are asking about rotary evaporators used in laboratories. In fact, there are many types of rotary evaporators. Let’s first look at the definition of rotary evaporators. Rotary evaporators are also called rotary evaporators and are commonly used in laboratories. The equipment consists of motors, distillation flasks, heating pots, condenser tubes, etc. It is mainly used for continuous distillation of volatile solvents under reduced pressure, and is used in chemistry, chemical engineering, biomedicine and other fields.

Its working principle is to use electronic control to make the flask rotate at a constant speed at the most suitable speed to increase the evaporation area. The evaporation flask is under negative pressure by means of a vacuum pump. The evaporating flask is placed in a water bath for constant temperature heating while rotating, and the solution in the bottle is heated, diffused and evaporated in the rotating flask under negative pressure. The rotary evaporator system can be sealed and reduced to 400-600 mmHg; the solvent in the distillation flask is heated with a heating bath, and the heating temperature can be close to the boiling point of the solvent; it can also be rotated at a speed of 50-160 rpm, Make the solvent form a thin film and increase the evaporation area. In addition, under the action of the high-efficiency cooler, the hot vapor can be quickly liquefied to accelerate the evaporation rate.


As we can see from the above, the rotary evaporator can be applied to a lot of fields, but what are the characteristics of the rotary evaporator that can be really applied to the laboratory? First of all, the volume must be small, because the laboratory rotary evaporator Most of them are used in a fume hood, too large volume will lead to wasted space.


Secondly, laboratories pay attention to efficiency. Testing of the same sample is often performed in batches and waiting for another batch. If batch processing of multiple samples can be performed at the same time, improving efficiency is very important.


Is there a timing function to reduce the mental attention of the experimenters and complete the work automatically? Another very important point is how to effectively prevent the solvent sample from being contaminated by the reflux caused by condensation. These seemingly annoying problems. It is trivial in front of this product below.


Array rotary evaporator is an innovative pre-processing equipment that can simultaneously concentrate and process multiple samples. It consists of multiple miniRotar rotary evaporator units, a vacuum system, and a solvent condensation recovery system. It can greatly improve the experiment while realizing multiple sample processing. Room space utilization.


The multiple miniRotars equipped with the array rotary evaporator can be used at the same time, and also support independent operation. They can independently perform temperature setting, speed adjustment, and vacuum release without interfering with the normal operation of other rotary evaporator units.


Extreme mini-saving space

miniRotar innovatively adopts the longitudinal design of the rotating shaft, which reduces the product width to 25cm, which is one third of the width of the traditional rotary evaporator. The 1.8m standard fume hood can hold up to 5 miniRotars, which fully saves the space resources of the fume hood.


Array combination-improve efficiency

The special interface design of miniRotar allows multiple units to be used in parallel, a total of one vacuum system and condensation recovery system. It is very suitable for the simultaneous processing of multiple samples to improve work efficiency.


Each miniRotar can independently set the temperature, speed, time and other working parameters, and can independently raise and lower the sample bottle.


MiniRotar 500s has an independent quick release vacuum button, which can release the vacuum independently without affecting the normal operation of other miniRotars.


Regular work-reduce nursing

MiniRotar500s has the ability to work regularly. The working conditions and working time can be set according to experience. When the time is reached, the miniRotar500s will automatically stop rotating, release the vacuum, raise the sample bottle, get out of the heating water bath, and automatically stop the evaporation and concentration of the sample.


Double protection-avoid pollution

miniRotar is equipped with a liquid backflow prevention interface, which can effectively prevent liquid backflow in the pipeline during sample processing, avoid contaminating samples, and ensure the accuracy of analysis results.
