Used Rotovap Machines
Rotary evaporators are instruments used for the efficient removal of solvents through evaporation. This process is one of the most widely used solvent evaporation methods for its excellence in extraction and distillation.
Selecting a Used Rotary Evaporator
Opting for a used rotary evaporator is an affordable solution for laboratories and research facilities. New lab instruments can get expensive, so getting used devices carefully vetted by experts is ideal.
Choosing the Right Rotary Evaporator
Finding the right rotary evaporator for your specific needs is important. Understanding rotary evaporator technology allows you to make the most of your device and streamline your process for maximum efficiency. Here are some important considerations when choosing a rotary evaporator:
Volume capacity: Rotavap volume capacities can go from 2 to 50 liters. Select one that can accommodate your specific volume needs.
Temperature control: Samples have varying heat sensitivity. Highly sensitive samples may get destroyed in the flasks, so look for an evaporator with temperature control. Consider one with reliable heating and cooling capacity, as well.
Lab space compatibility: The rotary evaporator is bound to take up valuable space in your lab. Remember that the bigger the volume capacity, the bigger the device.
Understanding Flasks and Their Roles in Rotary Evaporation Processes
There are two flasks in rotary evaporator technology — the rotating evaporation flask that rotates at a predetermined speed and the receiving flask, which collects the distilled sample and recycles the solvent steam.
The most common evaporator flask types are round-bottom, pear-shaped and flat-bottom. Made from high-quality borosilicate glass, these flasks can withstand high heat and have strong resistance against acids and other substances.
The Impact of Popular Manufacturers on Rotary Evaporator Technology
Rotary evaporators have been a staple in laboratories for many years. But recently, rotary evaporators from different brands have entered other industries. Lab stand and flask usage have found new meanings in molecular gastronomy, biofuel extractions, the alcohol industry and mixology.
Still, they remain reliable scientific instruments, particularly leading manufacturers' models. Check out these popular brands and devices:
Genser Scientific Instruments: The PILOTVAP 10 Rotary Evaporator features a patented pendulum system and standard controls for vacuum, aeration, temperature and speed. This easy-to-use device also has high-performance sealing and protection systems for added safety.
BUCHI: Their Rotavapor R-210 Rotary Evaporator is compatible with flask sizes ranging from 50 to 4000mL. Its modular design gives it flexibility to meet various evaporation requirements.

Frequently Asked Questions
Also known as a rotovap, a rotary evaporator is a device that removes solvents, concentrating the non-volatile components or separating solvents based on volatility. It is a crucial instrument in chemistry projects or any operation involving the separation of mixtures.
Some of the most important features of your used rotary evaporator include:
- Vacuum system: The vacuum system is what facilitates a faster evaporation process by creating different pressure conditions within the system.
- Evaporator flask: This is the container where you place your initial sample. It is connected to a motor that rotates it through the evaporation process.
- Heated fluid bath: This bath holds the evaporator flask as it rotates, evenly heating the solution to start evaporation.
- Condenser: As the solution evaporates, it goes through the condenser to recondense as a liquid. The liquid then drains into a separate flask underneath the condenser, providing you with a separated fluid sample.
A rotary evaporator uses pressure levels to create conditions that lower the boiling point for samples. The solution is placed in an evaporation flask, which rotates in place to expand the sample's surface area. Then, the evaporator slowly brings the sample up to its boiling point, allowing certain materials to be evaporated and separated from the rest. The process continues until the solvent separates from the solute, so that the solvent can be collected.
Rotary evaporators are used for separating mixtures in chemical and biomedical applications.
