What are Rotovaps used for?

What are Rotovaps used for?

A rotary evaporator (also called as “rotavap” or “rotovap”) is a device used in labs for the efficient and gentle removal of solvents from samples by evaporation.

What is Buchi Rotavapor?

The Rotavapor® R-100 is an entry-level rotary evaporator that meets the essential needs in economical evaporation and is developed according to BUCHI’s high-quality standards. Evaporating flask size:50 – 4000 mL. Lift mechanism:Manual. Temperature range:20 – 95 °C.

How much does a rotary evaporator cost?

The cost to buy a new EcoChyll rotary evaporator can range from $60,000 and $150,000.

Can you rotovap acetonitrile?

Yes, you should be able to completely remove the organic solvent Acetonitrile by freeze drying the flow through. You can then re-suspend the peptides in solution A (mainly aqueous water) and purifiy the peptides as instructed.

Can rotary evaporator separate two volatile liquids?

Rotary evaporators are types of equipment that are designed to separate various types of liquids or substances from concentrate materials or mixtures. For instance, one can use this equipment to remove water from a mixture of miscible liquids that have different boiling points.

What is a woulff bottle?

A Woulff bottle is a vessel with two (or sometimes three) outlets. Peter Woulff (1727-1803), a chemist of apparently Irish descent, described the form in 1767.

How long does rotary evaporator take?

Removal of solvent by a rotary evaporator is superior to evaporation under atmospheric pressure for many reasons. The process is much quicker (often takes less than 5 minutes), uses lower temperatures (so decomposition is unlikely), and uses less energy than boiling with a heat source.

At what temperature does acetonitrile evaporate?

if you put the heating bath of your rotavap to 40°C, Acetonitrile will start evaporating @ approx. 90 mbar; if the pressure decreases to about 40 mbar, the AcN is gone.
