Rotary Evaporator

Rotary evaporators are essential laboratory instruments used to efficiently and gently remove solvents from samples through evaporation. They operate by rotating the sample flask under reduced pressure, which lowers the boiling point of the solvent, enabling rapid solvent removal without degrading the sample. This makes them indispensable in chemical, pharmaceutical, and biological research for sample preparation and purification tasks.

In addition to their solvent removal capabilities, rotary evaporators provide precise temperature control and vacuum regulation, ensuring optimal conditions for various types of samples and solvents. Their applications span from concentrating solutions, recovering solvents, to synthesis processes, proving their versatility and utility across research labs, academic institutions, and industrial environments.

Types of Rotary Evaporators Your Laboratory May Need


Vacuum Pump

Vacuum Pump


Vacuum pumps are critical accessories for rotary evaporators, as they create the reduced pressure environment necessary to lower solvent boiling points. The efficiency and reliability of a vacuum pump directly influence the performance of the evaporator, impacting evaporation speed and sample integrity. Choosing the right vacuum pump depends on the solvent being removed, desired vacuum level, and compatibility with the rotary evaporator model.

At Kalstein, we offer a range of vacuum pumps with varying capacities and vacuum levels, suited for different rotary evaporator setups. Whether your application requires oil-sealed pumps for high vacuum or diaphragm pumps for solvent safety, our catalog accommodates your laboratory’s needs, ensuring efficient solvent evaporation with minimal contamination risks.

What You Need to Know Before Selecting a Rotary Evaporator and Making an Investment

Key Factors to Consider

When selecting a rotary evaporator, important factors include the evaporation capacity, heating bath stability, rotation speed range, and ease of maintenance. These elements determine the unit’s efficiency and suitability for different laboratory applications. Additionally, the quality of vacuum pump integration is essential for consistent performance.

Compatibility with different types of solvents and sample volumes is crucial. The materials used in construction, such as corrosion-resistant glass or stainless steel, affect durability and safety. User-friendly control panels and safety features also play a significant role in efficient and secure operation.

Price Range in the Market

The price range of rotary evaporators varies widely depending on the size, features, and included components. Basic units suitable for educational or low-throughput labs start at reasonably affordable prices, whereas premium models with advanced automation and large capacity can reach higher price points.

Vacuum pumps often sold separately can also impact the overall investment cost. Maintenance, warranty, and after-sales support services offered by the supplier should be considered when evaluating price versus value for your laboratory budget planning.

Value for Money

Achieving the best value for your investment requires balancing initial cost with reliability, durability, and ongoing operational expenses. Kalstein’s rotary evaporators are designed to provide consistent performance and low maintenance costs, delivering excellent return on investment for research and industrial applications.

While cheaper models might seem attractive, investing in equipment with robust build quality and technical support often results in longer-lasting service life and fewer disruptions. Cost-effective consumables and spare parts availability also contribute to overall cost efficiency.

Expected Lifespan Based on Use and Maintenance

The expected lifespan of a rotary evaporator depends on usage frequency, type of solvents processed, and adherence to maintenance schedules. Proper cleaning and timely replacement of seals, bearings, and vacuum pump oil are vital for extending operational life.

With regular calibration and preventive maintenance, Kalstein rotary evaporators can provide many years of reliable service. Our support team offers assistance to ensure your equipment continues performing optimally throughout its service life.
