Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — your trusted manufacturer of high-performance laboratory and industrial evaporation equipment since 2015. Our Low-Temperature Rotary Evaporator (Model: 20L, 304 SS, 0.1 MPa vacuum, digital temperature control) is engineered to meet the rigorous demands of solvent recovery, concentration, and crystallization in research, pilot plant, and production environments. With over 200 skilled employees and a factory spanning 10,000–30,000 square meters, we deliver precision equipment backed by ISO9001 and other quality management certifications. This rotary evaporator combines corrosion-resistant 304 stainless steel construction with a large 20-liter flask, a powerful 0.1 MPa vacuum system, and an advanced digital temperature controller to ensure gentle, low-temperature evaporation that preserves heat-sensitive compounds while maximizing yield.
Key Features & Technical Specifications
- 304 Stainless Steel Construction – The main body, heating bath, and condenser are crafted from high-grade 304 SS, offering excellent resistance to acids, alkalis, and solvents. This ensures long service life and easy cleaning even under harsh chemical environments.
- 20L Large Flask Capacity – Ideal for lab-scale to pilot-scale evaporation. The generous 20-liter round-bottom flask allows processing of larger volumes in a single batch, boosting efficiency.
- 0.1 MPa High Vacuum Level – The system maintains a stable vacuum down to 0.1 MPa (absolute pressure ~100 mbar), enabling low-temperature boiling of solvents. This is critical for heat-sensitive materials like natural extracts, pharmaceutical intermediates, and biological samples.
- Digital PID Temperature Control – A microprocessor-based controller accurately regulates the heating bath temperature within ±1°C (range: room temperature to 180°C). The digital display provides real-time temperature readings, and the system automatically adjusts heating power to avoid overshoot.
- Variable Rotation Speed (0–200 rpm) – The motor-driven flask rotation is steplessly adjustable to optimize film formation and mixing, enhancing evaporation rate. A smooth, quiet operation is ensured by a brushless DC motor.
- Efficient Condenser – A coil-type glass condenser (DN15 connection) with a large surface area ensures rapid condensation of vapors. Optional vertical or recirculating chiller system can be added for higher condensation efficiency.
- Safety Protections – Includes overheating protection, over-temperature alarm, and emergency stop button. The heating bath is equipped with a separate overtemperature limit sensor.
- User-Friendly Design – The lifting mechanism (manual or electric) allows easy raising and lowering of the heating bath. All controls are centralized on a front panel, and the glass components are secured with quick-release clamps.

Advantages & Benefits for Your Processes
- Preserve Heat-Sensitive Compounds – The combination of low-temperature operation (via vacuum and digital control) minimizes decomposition, oxidation, or degradation of valuable substances such as essential oils, vitamins, flavors, and active pharmaceutical ingredients.
- High Recovery Rates – The large flask, efficient condensing system, and precise vacuum control enable >95% solvent recovery for most common organic solvents (ethanol, methanol, acetone, ethyl acetate, etc.), reducing operational costs and environmental impact.
- Durable & Hygienic Construction – 304 SS components resist corrosion from acidic or alkaline feedstocks, and the smooth surfaces are easy to clean. The borosilicate glass flasks and condenser allow visual monitoring of the process.
- Flexible & Customizable – Options include alternative flask volumes (10L, 30L, 50L), electric lifting, explosion-proof motor, recirculating chiller, and vacuum pump integration. We can adapt the unit to your specific application requirements.
- Cost-Effective Production – As a direct manufacturer, we offer competitive pricing without sacrificing quality. Our factory produces over 500 units annually for clients across North America, Europe, Asia, and Africa.
- Easy Operation & Maintenance – The digital control panel is intuitive; operators can set parameters with a few touches. The modular design allows quick replacement of glassware or seals.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum vacuum pressure achievable with this rotary evaporator?
A: The system can maintain a vacuum level down to 0.1 MPa (absolute ~100 mbar). With a compatible high-quality vacuum pump, you can achieve lower pressures (e.g., 10 mbar) for even lower boiling points. Please note that 0.1 MPa is the rated value under normal conditions. -
Q: Can this unit handle corrosive solvents like hydrochloric acid or sulfuric acid?
A: The 304 stainless steel heating bath and frame offer good resistance to many weak acids and bases, but for strong acids (e.g., concentrated HCl, H₂SO₄) we recommend using a PTFE-coated bath or glass-only wetted parts. Contact our sales team for custom solutions. -
Q: What is the temperature control accuracy? Can it maintain very low temperatures?
A: The digital PID controller provides ±1°C accuracy over the range from ambient to 180°C. For low-temperature evaporation below ambient, you will need a recirculating chiller (optional) to cool the heating bath and/or condenser. The system itself does not actively cool below room temperature. -
Q: Is the flask removable and interchangeable?
A: Yes, the 20L round-bottom flask is attached via a standard ground glass joint (NS 29/32 or larger) and a quick-release clamp. It can be easily removed for cleaning or swapped with flasks of different volumes (10L, 30L) available upon request. -
Q: Does this rotary evaporator include a vacuum pump and chiller?
A: The standard package includes the evaporator unit with heating bath, condenser, flask, and digital controller. Vacuum pump and recirculating chiller are not included but can be supplied as optional accessories. We recommend our compatible diaphragm or rotary vane pump. -
Q: What certifications does your factory hold? Is the evaporator CE/UL certified?
A: Our factory is ISO9001, ISO14000, OHSAS18001 certified, and we can provide other certifications like HACCP upon request. For specific export regions, we can arrange CE or UL certification as a customized service. Please consult with your sales representative. -
Q: What is the warranty period and after-sales support?
A: We offer a standard 12-month warranty covering defects in materials and workmanship. Technical support is available via email, phone, or video call. Spare parts (glassware, seals, motor brushes) are stocked and can be shipped quickly. -
Q: How long is the lead time for an order?
A: Typical lead time for a standard 20L rotary evaporator is 15–25 working days after order confirmation and payment. For customized models, it may extend to 30–40 days. Rush orders can be expedited upon negotiation.
