Generally, the component liquids of interest in applications of rotary evaporation are research solvents that one desires to remove from a sample after an extraction, such as following a natural product isolation or a step in an organic synthesis.

Thus, the pressure has to be increased or the cooling temperature of the condensation assembly decreased.

Skip to main content. This item doesn’t belong on this page.

What does this price mean? When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase “rotary evaporator”, though use is often rather signaled royavapor other language e. Vacuum evaporators as a class function because lowering the pressure above a bulk liquid lowers the boiling points of the component liquids in it.

There seems to be a problem serving the request at this time. The heating bath temperature, rotation speed and lift position are shown on the integrated heating bath display. All images taken in house of the bchi s being sold, except for multiple quantities where item received will be in similar or better condition.

Ergonomic handle to conveniently change the position of the lift. Both r and b function but b needs powercord. Extra caution must also be applied to operations with air reactive materials, especially when under vacuum. When using distilled water, 0.

Rotary evaporators can also be equipped with further special traps and condenser arrays that are best suited to particular difficult sample types, including those with the tendency to foam or bump. Only the Glassware pictured is included. How do I determine the optimum evaporation conditions? No risk of scalding when handling the evaporation flask Lower evaporation of heating liquid e.

Our Customers Voice of the Customer. It also protects the operator from broken bits of glass as well as chemicals in case of glass breakage. However, careful application also allows removal of a solvent from a sample containing a liquid compound if there is minimal co-evaporation azeotropic behaviorand a sufficient difference in boiling points at the chosen temperature and reduced pressure.

Operation under vacuum is possible to protect the product from stress and to improve efficiency. This can also occur when taking certain unstable compounds, such as organic azides and acetylidesnitro-containing compounds, molecules with strain energyetc.

More refinements More refinements A leak can draw air into the apparatus and a violent reaction can occur. Voice of the Customer. Electronic and manual version available. Unit powers on, with lit power indicator light and spinning rotary drive.


Commercial instruments are available that include the basic features, and various traps are manufactured to insert between the evaporation flask and the vapor duct. If the distillation parameters are not chosen according mnaual the “delta 20 rule”the condensation is not complete and vapor is entering into the pump.

Only minor surface marks from normal usage Manual height adjuster works r-24 expected. Evaporation under vacuum can also, in principle, be performed using standard organic distillation glassware — i.

Use to rpm for maximum turbulence at high durability. Buchi rotavapor rotary evaporator R with B water bath and condenser.

The rotation speed, as well as heating bath temperature and lift position, are shown on the integrated bath display.
