How to tell the quality of rotary evaporator

Rotary evaporator is a commonly used evaporation and purification instrument in the laboratory, mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. So, how to tell  the quality of rotary evaporator?

Ways to tell the quality of laboratory rotary evaporator

1. Seal ring

The seal ring is the key to ensure air tightness. Nanbei instrument adopts double sealing with PTFE + fluorinated rubber, which is resistant to corrosion and zero pollution, without costs of frequent replacement later.

2. Glass quality

Nanbei instrument uses high borosilicate glass, which can withstand higher temperature differences and meet international standards.

3. Motor/controller

The motor/controller is the heart of the vacuum rotary evaporator and ensures its smooth operation.

4. Heating pot liner

The heating pot of Nanbei Instrumen is made of 304 stainless steel, which can be used for both water and oil and has a wide temperature range.

5. Other factors

Other factors mainly include electric or manual lifting, whether there is a vacuum gauge,  whether the feeding pipe has a valve , and whether the collection bottle gets a discharge valve.
