Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

Dec 20, 2019 Working Principle of a Rotary Evaporator. A rotavap evaporates solvents from samples by utilizing the principle that the solvent will have a lower boiling point at a reduced pressure. Specifically speaking, the stepless speed regulation is adopted to make the evaporation flask rotate at a constant speed. By the rotation, materials can form a ...

Mar 15, 2022 A small freeze dryer is a technology that uses the principle of sublimation to dry. It is a process in which the dried substance is quickly frozen at a low temperature, and then in an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor and escaped. .
Nov 03, 2021 Although this operation, in principle, could be carried out by simple distillation, the fastest and most convenient method is the use of a rotary evaporator for distillation under reduced pressure. It basically consists of an electric motor, which causes the rotation of a tube attached to a ground glass joint guide tube.

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
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.

It is capable of a manually adjustable rotation speed of 20 to 280 rpm and equipped with an action jack lift for manual lifting of the evaporating flask. The R-100 Rotavapor can be purchased with either a Vertical Condenser …
The rotatory evaporator working principle is that the boiling point of liquids lowers on decreasing their pressure. This allows the solvent to vaporize at lower temperatures than when boiled in a normal atmosphere. You should choose a vacuum pump for your rotavap that will guarantee an improved evaporation efficiency.
