Rotary evaporators, commonly known as rotavaps, are indispensable in chemical laboratories for efficient and gentle solvent removal. By rotating a flask containing a sample in a heated water bath under vacuum, solvents can evaporate at significantly lower temperatures. This makes rotary evaporators ideal for precise solvent recovery, sample preparation, and various industrial processes requiring high efficiency and accuracy.
Our rotary evaporators offer cutting-edge features and rugged construction to support advanced laboratory workflows. Here's what makes them stand out:

Digital controls for temperature and rotation speed ensure precision and reproducibility, delivering
consistent, high-quality results in every experiment.
Efficient Design
With vertical glassware and optimized bath volume, our evaporators enable rapid heating and thorough solvent
recovery for time-sensitive applications.
Robust Construction
Built with solvent-resistant materials like PTFE and Viton, our rotavaps are engineered for long-term use in
demanding lab environments.
User-Friendly Interface
Intuitive digital displays and controls make operation straightforward, streamlining complex procedures and
enhancing overall productivity.
Safety Features

during operation.
Choosing the right rotavap involves evaluating several important factors to match your specific laboratory needs:
Capacity
Ensure the evaporator can accommodate your typical sample volumes to prevent workflow interruptions and
increase efficiency.
Temperature Control
Look for precise, programmable temperature controls for both the bath and condenser to achieve optimal solvent
evaporation conditions.
Material Durability
Opt for solvent-resistant construction using materials like PTFE and Viton, which stand up to corrosive
environments and extend product lifespan.
Safety Features
Important safety functions such as auto shut-off and overheat protection ensure safe operation in high-stakes
lab settings.
Ease of Use
Choose models with digital displays, ergonomic controls, and quick-lock systems to simplify setup and
operation.
Investing in a high-performance rotary evaporator ensures efficient, safe, and precise solvent recovery. Our rotovaps are trusted by researchers and industrial users for their advanced design, durability, and ease of use—making your lab workflow smoother and more productive.
What is the principle behind a rotary evaporator?
Rotary evaporators reduce the boiling point of solvents by lowering pressure and increasing surface area
through flask rotation, enabling gentle and efficient evaporation.
Can rotary evaporators be used for all types of solvents?
Most organic solvents can be used; however, effectiveness may vary based on boiling point and chemical
stability.
What are the safety precautions when using a rotary evaporator?
Always operate in a ventilated area, use appropriate PPE, and ensure proper assembly to avoid spills or vacuum
leaks.
How do I maintain a rotary evaporator?
Clean glassware regularly, inspect seals, check the vacuum pump, and ensure the heating bath is functioning
properly.
Can rotary evaporators be used for large-scale operations?
Yes. While common in labs, larger industrial models are available for commercial-scale evaporation needs.
