Rotary Evaporator

There are many reasons to prefer the use of a rotary evaporator to concentrate samples in the laboratory. First, it is a very controlled method to evaporate the solvent, obtaining a correct and precise concentration of the sample. In addition, the fact that the sample is not damaged during the process is very important, as it prevents the loss of precious material.

Another advantage of the rotary evaporator is that it allows you to work with small samples, which is very useful if you need to concentrate a very small sample. Another aspect to keep in mind is that the concentration time is usually very short, allowing to save time and effort.

In short, the rotary evaporator is a very efficient and useful instrument for concentrating samples in the laboratory, since it allows precise concentration control, prevents damage to the sample and is very fast.

Our Best Selling Rotary Evaporator

Large capacity and large opening of evaporating flask give larger evaporation surface. The evaporating flask keeps rotating when it is constantly heated by water bath, and solvent evaporates more efficiently under vacuum condition. It can be used for pilot-scale production in biology engineering, pharmaceutical industry, chemical industry and food processing. It usually works with water circulating vacuum pump, diaphragm vacuum pump, recirculating chiller, constant-temperature circulator, low temperature circulating pump, etc.

  • Patented technology of double sealing of Teflon(PTFE) and FV rubber ensures the negative pressure level.
  • Automatic switch valve makes continuous collection possible without affecting vacuum degree and without stopping distillation.
  • Teflon discharge valve is corrosion resistant and contamination free.
  • Water bath jacket protecting operator from scalding by hot liquid.

Rotary Evaporator Assembly

Potential risks include implosions resulting from the use of faulty glass items such as star-shaped cracks. Explosions can also occur by concentrating unstable impurities during evaporation. Accordingly, it is recommended that users of equipment take precautions to avoid contact with rotating parts, especially entanglement of loose clothing, hair or necklaces. In these circumstances, the winding action of the rotating parts can attract users to the apparatus, which causes the breakdown of glassware, burns and chemical exposure. In addition, additional caution should be applied to operations with reactive materials in air, especially when under vacuum. A leak can draw air into the device and a violent reaction can occur.
