Also known as rotovaps, the rotary evaporators are popular laboratory equipment that are used in research. The equipment is used for the removal of solvents from samples by the method of evaporation. Suppose you are looking to start a new laboratory or planning to update your old one, or trying to replace the old equipment with new devices, you should ask yourself some important questions before you make the purchase. 

Here we will discuss the points you should consider before you purchase a rotary evaporator. 

Size of laboratory 

Keep in mind that the rotary evaporators take up a considerable amount of space and even require some extra space surrounding them. So, before you buy the rotary evaporators, do consider the size of the laboratory and the amount of space you have to keep the device in your lab. You can either keep the rotovap on the floor or go for the benchtop models. Just make sure you select a model which does not block the workflow of your laboratory. 

Volume of sample 

Rotary evaporators come in different shapes and sizes. While some rotovaps might be of 0.25L, some industrial unit models might be as big as 50L. However, before you shell out the money, do consider the size of the device you need for your requirements. If you need to accommodate different volumes of samples, then you might go ahead and buy multiple rotary evaporators. 

Safety precautions

While working in the laboratory, safety is of paramount importance. Now you might say that evaporation is a simple method but then any kind of accidents can occur due to the explosion of glassware and nitrogen-containing compounds. So, it is highly recommended to take all the necessary precautions to avoid any kind of contact with the rotating parts of the rotary evaporator, especially like hair or jewellery. 

Evaporation speed 

Before purchasing the rotovap, do consider the evaporation speed of the device. The evaporation speed of the rotating evaporator depends on the rotation speed of the sample bottle, the degree of vacuum in the rotovap, the temperature of the water bath and how efficient the condensation recovery unit. 

Nature of the sample

Choosing the right samples is also important. Now, samples like acids can destroy the material of the rotary evaporator. So, if you are using abrasive materials, it’s best to use steel or acid-resistant materials. There are some samples which are resistant to heat and thus need constant monitoring.
