When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase rotary evaporator , though use . Кеш Схожі Перекласти цю сторінку квіт. Rotary evaporators (also called rotavaps) are used to remove solvents from reaction mixtures and can accommodate volumes as large as liters. They are found in almost every organic laboratory, since they allow performing this task very quickly.

A typical rotary evaporator has a water bath that can be . Shop with confidence.

Here is a demonstration on how. Rotary Evaporator is used to remove high boiling solvents under low pressure. This is a video from FabioChem demonstrating the correct way to use a rotary evaporator ( rotavap ). Definition: A piece of apparatus consisting of a motor unit that rotates the evaporation flask, a vacuum system, a heated water bath and a condenser, which is used to remove solvents from samples under reduced pressure. Sorry, your browser does not support Java.

To use the applet, simply fill in all the boxes and press return or click the calculate button. To change between binary and ternary mixtures, click on the button at the top of the applet display. It is also possible to calculate the . Essentially there are three Stuart rotary evaporators, the motorised stand is the same throughout but the glass orientation changes.

Most labs use a simple water aspirator vacuum on their rotavaps, so a rotavap. If you follow the instructions carefully, it is the fastest, most efficient and most environmentally friendly way of removing a volatile solvent from a non-volatile sample. A high-quality rotary evaporator ( rotavap or rotovap for short) is a thing of beauty. These top-of-the-line units rely on exceptional engineering and extreme precision to get the job done. In many commercial labs, these machines need to be running around-the-clock without fail.

Several system packages are available to suit different needs and budget conditions. Request a live, in-lab demonstration and discover the unique advantages or KNF Rotary . A piece of laboratory equipment used to gently evaporate solvents from a chemical solution in a temperature controlled environment. The Origin of the Rotavap.

Years ago, a non-chemist friend of mine visiting my lab asked me what a rotavap was for. Department of Chemistry. University of Michigan.

Rotavapor is the name of a laboratory instrument that concentrates a sample by evaporating off the solvent.
