50L Pilot Scale Rotary Evaporator | Industrial Solvent Recovery System
Bridge the Gap Between Lab Research and Commercial Production with Reliable Batch Processing
The 50L Pilot Scale Rotary Evaporator is engineered for scale-up evaporation, concentration, and solvent recovery. It serves as the critical intermediate step when standard laboratory equipment (2L/5L) no longer meets throughput demands, but full-scale industrial systems are not yet required.
This robust system delivers high-capacity processing for chemical manufacturers, pharmaceutical facilities, botanical extractors, and process equipment distributors who require precise, repeatable parameters during scale-up.

Key Advantages & Engineering Features
Risk-Reduction in Process Scale-Up
Moving directly from a 5L lab unit to a multi-ton plant introduces significant thermodynamic risks. The 50L system allows chemical engineers to simulate real production mechanics-such as vapor velocity, thermal fluid dynamics, and boiling behavior-generating the precise data required for industrial plant scaling.
Thermal Protection for Heat-Sensitive Compounds
Operating under high vacuum (below -0.098 MPa) lowers the boiling points of target solvents. This permits rapid evaporation at reduced temperatures, preventing thermal degradation, oxidation, or loss of potency in active pharmaceutical ingredients (APIs) and delicate botanical compounds.
High-Velocity Vapour Condensation
Equipped with a large-surface-area dual-coil vertical condenser, the system maximizes vapor-to-liquid heat transfer. It achieves high recovery rates for volatile solvents (including Ethanol, Methanol, Acetone, and Hexane), directly lowering operating costs by recycling raw materials.
Uniform Thin-Film Evaporation
The PID-controlled rotation drive creates a continuous, uniform liquid film across the inner surface of the 50L flask. This maximizes the active heating area, eliminates localized hot spots, reduces distillation times, and minimizes the "bumping" or foaming common in viscous mixtures.
Industrial-Grade Corrosion Resistance
All wetted parts consist of high-purity GG-17 borosilicate glass and premium PTFE seals, ensuring total chemical inertness against aggressive acids, bases, and volatile organic compounds (VOCs). The entire assembly is supported by a rigid stainless steel (SUS304) mobile frame with lockable casters.
Target Applications & Supporting Ecosystem
Pharmaceuticals & Fine Chemicals: Scale-up synthesis of APIs, crystallization preparation, and high-purity solvent removal.
Natural Product Extraction: Large-volume concentration of botanical extracts and bioactive compound separation.
Turnkey Integration: For maximum efficiency, a 50L rotary evaporator requires matching ancillary equipment. We manufacture compatible recirculating chillers and chemical-resistant vacuum pumps to deliver a fully integrated distillation package.
FAQ
Q: How does this system handle hazardous or volatile chemical environments?
A: For environments involving flammable solvents, we provide certified explosion-proof (Ex-proof) upgrades. This replaces the standard drive motor, heating elements, wiring, and control enclosures with ATEX/IECEx compliant components suitable for Class I, Div 1/Div 2 environments.
Q: What is the material compatibility of the sealing system?
A: The vacuum sealing system utilizes a combination of PTFE and specialized fluororubber (Viton). This design withstands continuous exposure to aggressive industrial solvents like chloroform, ethyl acetate, and hexane without degrading the vacuum depth.
Q: How do you ensure the large glass components arrive undamaged during international transit?
A: All delicate glassware is packed inside heavy-duty, export-standard plywood crates. Components are embedded in custom-molded, high-density foam that absorbs shock and vibration during sea or air freight.
Q: What are your OEM capabilities and warranty terms for overseas distributors?
A: We offer full OEM/ODM options, including custom control interfaces, tailored glass configurations, and private labeling. The system comes with a 1-year comprehensive warranty on core mechanical/electrical parts, and we maintain a permanent stock of wear-and-tear parts (PTFE seals, gaskets) for immediate global dispatch.
