The rotary evaporator extraction device from Xi'an Bioland is the result of over 15 years of technical excellence in heat separation technology. Our business-level equipment has great vacuum performance and can reach a maximum pressure of less than 1 mbar. It can also rotate precisely at speeds ranging from 10 to 280 RPM. Our system has a combined heater, chiller, and vacuum pump design that makes sure the best liquid recovery rates of over 95%. The PTFE and Viton double closing system makes sure that there is no air leakage, and the double-layer cooling coils make the condenser work more efficiently. Each unit goes through strict 24-72 hour tests where it is left on all the time and its pressure leak rate (<1 mbar/min) is checked. Our product solutions meet GMP/FDA compliance standards for pharmaceutical, chemical, and biotechnology uses. They are made with chemical-resistant Borosilicate 3.3 glasses and have CE, ISO, UL, and SGS certifications to back them up.
Rotary evaporator is an evaporating instrument widely used in laboratory.Suitable for reflux operation, rapid evaporation of a large number of solvents, concentration of trace components and reaction processes requiring stirring, etc.

The rotary evaporator extraction process combines three synchronized physical mechanisms to achieve efficient solvent separation.
Vacuum Reduction
Using a high-performance vacuum pump, the system pressure is reduced below air levels. Solvents with a lower boiling point are safer for use with heat-sensitive compounds since they evaporate at lower temperatures.
Rotational Film Formation
As the evaporation flask continues to spin, your sample is evenly distributed throughout the inner glass surface, forming a thin layer. The result is a faster rate of evaporation at a constant temperature because the surface area of the liquid is increased.
Controlled Heating
The ideal temperature for vaporization is provided by the hot bath. To get optimal results while minimizing sample degradation, adhere to the "Rule of 20" and maintain a bath temperature 20°C higher than the vapour temperature and a colder temperature 20°C lower.
Efficient Condensation
Solvents that have been turned into vapour move to the double-layer condenser through the vapour tunnel. The chiller moves cooling through these coils, quickly turning vapours back into liquids that can be collected and used again.
With this organized process, your valuable extracts can be cleaned quickly while still keeping their structure integrity.
Pharmaceutical Industry
Active pharmaceutical ingredients (APIs) must be extracted and cleaned up while the safety of the substance is maintained. Feel safe working with thermolabile drug intermediates.
Biotechnology Research
Concentrate proteins, peptides, and biological data without damaging them with heat. Provide lab research with data that can be relied on and repeated.
Essential Oil Production
Get back volatile aromatic chemicals that are found in plant products. Use soft processing to keep delicate scent patterns.
Chemical Synthesis
During multi-step chemical processes, get rid of reaction solvents quickly. Shorten the time it takes to make a product.
Food & Beverage
Make concentrated ingredients and flavours for making products. GMP-compliant tools will help you meet food safety guidelines.
Cosmetics Manufacturing
Make high-end skin care products with plant ingredients that have been cleaned up. Check the quality and balance of the ingredients.
New Materials Development
Specialized chemicals and products are processed for use in new materials. Help new ideas by having flexible extraction options.
Our manufacturing facility maintains rigorous quality standards to ensure you receive reliable equipment.
ISO 9001 Certification
Our quality management system follows international standards for consistent manufacturing excellence. Regular audits verify ongoing compliance.
CE Safety Compliance
All electrical components meet European safety directives. You can operate with confidence knowing equipment meets strict safety protocols.
GMP/FDA Standards

Comprehensive Testing Protocols
Each unit undergoes vacuum integrity testing, rotation stability verification, temperature bath homogeneity checks, and glassware stress analysis before shipment.
Q: How do I prevent bumping during operation?
A: Turn the wheel on before you use the cleaner. Lower the pressure slowly with the vacuum device instead of all at once. To make things safer, put a bump trap between the vapour tube and the flask. The temperature difference known as the "Rule of 20" also helps keep drainage fixed.
Q: What causes low solvent recovery rates?
A: Usually, this means there is a vacuum leak or not enough cooling capacity. Inspect all the O-rings and glass parts to make sure they are properly sealed. Make sure your chiller has the right amount of power for the liquid and rate of evaporation you're using.
Q: Can I process water-based samples?
A: but you need to be extra careful with water. You will need a strong chiller, a high-quality vacuum pump that can reach less than 10 mbar, and warmer bath water. Because of water's high boiling point and rate of vaporization, the system needs stronger parts.
Q: How often should I replace vacuum seals?
A: For intensive use, inspect PTFE/Viton seals monthly. Replace immediately if you detect vacuum pressure drops or solvent odors. Proper lubrication extends seal life significantly.
Q: What rotation speed should I use?
A: Start with moderate speeds around 100-150 RPM. Higher speeds increase surface area but may cause splashing. Lower speeds suit viscous samples. Adjust based on your specific solvent and sample characteristics.
Q: Do you offer training for operators?
A: Yes, we provide comprehensive operational guidance and technical documentation. Our support team remains available for questions throughout your equipment's lifetime.
