Expert Advice

What is the performance of an industrial Rotavapor®?

FAQ Performance industrial Rotavapor
Depending on the application and the settings, you achieve distillation rates up to 28 liter acetone per hour. With the Rotavapor R-220 SE continuous, large volumes of several hundred liters of solvents a day can be distilled or recycled in an unattended continuous way.

How can I optimize the distillation rate?

FAQ distilation rate R-220 SE
The distillation rate is mainly related to the amount of energy that is brought into the product. With a high temperature difference between the bath and the boiling point, the evaporation rate is higher. Helpful for a higher performance are also a fast rotation speed, larger evaporation flask and low cooling temperature.  

What kind of customization is available?

BUCHI offers a wide range of accessories. Furthermore there are tailor-made modifications according to your needs. As we operate our own glass-blowing and machine shop we are able to fulfill almost any special request.

What is the perfect glass configuration to perform a concentration of my sample?

descending assembly R-220

By concentrating your product the main focus is on speed to ensure the product is not exposed to heat
for a long time.

Common situations during the concentration process:

  • Bumping or foaming product
  • Uncontrolled concentration to dryness

Recommendation:

  • Descending glass assembly to ensure, that not product will accidently end in the receiving flask by bumping or foaming product.
  • Optional foam detector
  • Level sensor for defined concentration to a specific volume

What is the perfect glass configuration to recycle or purify solvents?

descending assembly D2 R-220

The main focus to recycle or purify solvents is to get the distillate as clean as possible. With a high recovery rate.

Recommendation:

  • The design of the descending assembly guarantees a better separation.
  • Additional condenser to reduce the emissions of low boiling solvents
  • Foam detector for foaming products
  • Level sensor to stop at a defined distilled volume

How safe is the industrial Rotavapor® from BUCHI?

Bath shield 11055364

Standard safety

  • All glass parts of Rotavapor® R-220 SE and R-250 apart from the evaporation flask are coated with a highly robust special plastic coating to ensure the maximum user protection
  • Safety cut-off in case of overtemperature to protect you and your product
  • Any failures will interrupt the system and set the Rotavapor in the safe mode

Recommended option

Manual flask handler for heavy, slippery and hot flasks

  • Prevention from flask falling in the bath
  • Allows safe transport of the flask
  • For a safe an stable parking of the evaporating flask

To protect the user and the evaporation flask, we offer an optional bath shield for every Rotavapor®.

Is additional automation possible?

FAQ Foam detector
With different accessories, different grades of automations are possible.Foam sensor, level sensors and other features will also help to reduce the observation time.
