Oct 22, 2021 This patented measuring principle can be used with the Vacuum Controller V-855. This arrangement is particularly suitable for solvent mixtures and gentle distillation to dryness. Automatic distillation – the answer to complex distillation tasks The R-210/215 Advanced combines the Rotavapor with the

Operating principle. The Rotavapor is essentially a distillation unit incorporating a rotating evaporation flask. The Rotavapor will evaporate solvent at a much faster rate than systems using stationary evaporation flasks. The rotation transfers a thin film of the liquid sample to the whole of the inner surface of the flask, markedly increasing ...

Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or rotovap, was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications.
