This is a practical question about the use of rotary evaporators ("rotovap"). So I'm asking for answers from people who actually use the things. A rotovap typically uses a cold condenser to condense the solvent into a collection flask. But the distillation is typically done under weak vacuum as well.

A rotary evaporator (or rotavap) is commonly used in chemical laboratories to remove solvents by evaporation.. The liquid is put in a round-bottomed flask and placed in the device. The rotavap spins and heats the flask and reduces the pressure inside by creating a vacuum.The vacuum makes the liquid evaporate at a low temperature than normal. The liquid becomes a gas and is collected by cooling .

Rotary evaporator - Wikipedia A simple rotary evaporator system was invented by Lyman C. Craig. It was first commercialized by the Swiss company Büchi in 1957. In research the most common form is the 1L bench-top unit, whereas large scale (e.g., 20L-50L) versions are used in pilot plants in commercial chemical operations.

The perfect peak shape: Five solutions to peak tailing .

Cause 1: Firstly, tailing can occur when secondary interactions take place.As a result, not all molecules travel through the column at the same speed and this causing tailing at the peak. Possible Solutions: To remedy this, you could try to lower the pH of the liquids so that silanol ionization is suppressed (pH 3). Reducing the pH keeps the silanols in protonated form, where interaction with .

Rotary Evaporation to Remove Solvent | Protocol

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.
