Product Overview
This automatic pilot-scale rotary evaporator manages solvent distillation and concentration at volumes between 10L and 50L. The system integrates electronic control of rotation speed, oil/water bath heating, system vacuum, and motorized flask lifting to replace manual mechanical adjustments. This consistency is required for repeatable process validation and protecting heat-sensitive active ingredients from thermal exposure during long runs.
Technical Features & Procurement Logic
Digital Process Control & Logging
• Technical Detail: The central control panel monitors and adjusts Rotation Speed (10–140 RPM), Bath Temperature (up to 180°C), Vapor Temperature, and Vacuum Levels.
Double-Sealing Vacuum System
• Technical Detail: The system achieves and maintains a stable operational vacuum down to ≤ 399.3 Pa (3 mbar) using a PTFE (Polytetrafluoroethylene) and Viton double-vacuum seal assembly.
Motorized Lift Assembly
• Technical Detail: A motorized vertical lift moves the entire heating bath and flask assembly automatically, supported by a mechanical safety override in case of power failure.
GG-17 High-Borosilicate Glass Componentry
• Technical Detail: All vapor ducts, condensers, and flasks are fabricated from GG-17 high-borosilicate glass, providing a low coefficient of thermal expansion (3.3×10 −6 K −1 ) and universal resistance to aggressive organic acids and solvents.
Configurable Condensation Arrays
• Technical Detail: The vertical triple-circulating coil condenser delivers a cooling surface area from 0.5 m 2 to 1.5 m 2 depending on the flask volume, achieving solvent recovery rates ≥ 95% for Ethanol, Acetone, and Hexane.
Certified Explosion-Proof (ATEX / IECEx) Options
• Technical Detail: For hazardous environments, systems can be built with Ex-d II BT4 explosion-proof motors, isolated control enclosures, and anti-static grounding.

Modular Integration: Complete turnkey packages including chemically inert diaphragm vacuum pumps, recirculating chillers, and custom glassware modifications.
Export Packing: All components are secured in ISPM-15 compliant, heavy-duty wooden crates to prevent damage during maritime or air freight transit.
Frequently Asked Questions
Q: What specific safety certifications are available for industrial facilities?
A: All systems carry standard CE certification. For facilities processing flammable solvents, we build configurations using ATEX or IECEx certified explosion-proof motors and controls, wired to your local electrical standards (e.g., 110V/60Hz or 220V/50Hz).
Q: What is the typical lifespan of the vacuum seals under daily use?
A: The primary vacuum seal uses a continuous-pressure PTFE composite ring backed by a Viton O-ring. In standard pilot-scale applications with organic solvents, the seals require visual inspection every 6 months and typical replacement once every 12 months to maintain the≤ 3 mbar baseline pressure.
Q: Can the glassware design be altered for specific chemical reactions?
A: Yes. Our factory operates an in-house glassblowing shop. We can modify the standard design to include jacketed flasks, dual-condenser arrays for low-boiling-point solvents, or continuous-feeding line adaptors according to your process layout.
Q: How are spare parts handled for international distributors?
A: We ship standard maintenance kits (PTFE seals, glass valves, vacuum gauges, and electrical relays) with the initial machinery order. Emergency replacement glass or parts are dispatched via priority air express to minimize facility downtime.
