Application: Evaporation of organic solvents

Two units of the BUCHI Rotavapor R-250 are extensively used on industrial scale for the evapo¬ration and recovery of organic solvents from the crude extracts of a very important medicinal plant 'Azadarichta Indica', commonly known as Neem. The material from these extracts has a variety of potential therapeutic uses.

Equipment: Rotavapor® R-250

BUCHI's Industrial Rotavapor is regularly working 8 hours approximately daily without any major breakdown. A self standing body and the motorized movement of the water bath make it very easy to operate. A single person can handle the 50 liter evaporating flask with the help of the flask handler (accessory provided by BUCHI) which is a great benefit.

Benefit / Conclusion:

The Industrial Rotavapor is a robust and reliable instrument with practically no downtime. The safety and the user-friendly features of the R-250 make it stand out compared to similar prod¬ucts available on the market.
