Product Overview
The Industrial Rotary Evaporator Series (10L - 100L) is engineered for pharmaceutical, chemical, and biotechnology facilities requiring continuous, large-volume solvent recovery and concentration. By integrating dynamic thin-film heat transfer with precise vacuum control, this system accelerates evaporation cycles while safeguarding the molecular integrity of heat-sensitive compounds. It serves as a reliable operational bridge between laboratory pilot scaling and full-scale plant production.
Technical Architecture & Engineering Features
Evaporation Dynamics & Thermal Protection
• Uniform Thin-Film Transfer: The continuous rotation of the GG-17 Borosilicate Glass 3.3 flask forces the liquid processing batch to form a consistent film across the entire inner wall. This maximized surface area accelerates evaporation kinetics without requiring excessive thermal input.
• Low-Temperature Distillation: Operating under deep vacuum significantly lowers the boiling points of organic solvents. This targeted depression protects active pharmaceutical ingredients (APIs) and delicate botanical extracts from localized overheating and thermal degradation.
Material Specification & Vacuum Integrity
• Pure Corrosion-Free Pathway: All vapor and liquid contact surfaces are lined exclusively with Borosilicate Glass 3.3 and solid PTFE. The complete absence of internal metal surfaces eliminates batch contamination and resists aggressive organic solvents, acids, and bases.
• Heavy-Duty Sealing Assembly: The system utilizes a main vacuum seal composed of self-lubricating PTFE composite paired with dual Viton O-rings. This engineering design maintains steady operational vacuum levels below -0.098MPa over long-cycle, 24/7 processing runs.
• Structural Rigidity: The primary load-bearing frame, structural cross-beams, and the integrated water/oil heating bath are fabricated from SS304/SS316L stainless steel. This ensures resilience against chemical vapors and permits standard clean-in-place (CIP) wipe-downs.
Operational Safety & Control Automation
• Hazardous Location Readiness: Standard configurations carry full CE certification. For facilities processing volatile or flammable solvents (such as Ethanol, Hexane, Acetone, or Chloroform), we provide optional ATEX / IECEx certified explosion-proof (XP) motors, fully enclosed control boxes, and armored wiring conduits.
• Parametric Monitoring: An integrated digital console provides real-time readouts of rotation speed (RPM), bath temperature, and vapor temperature. A motorized or counter-balanced lift system is integrated to allow safe, single-operator flask installation and removal.

FAQ
Q: How does the system handle highly corrosive acids during evaporation?
A: Because the entire vapor and fluid contact pathway consists strictly of GG-17 Borosilicate Glass 3.3 and pure PTFE seals, the system withstands strong organic and inorganic acids. It contains no vulnerable plastics or metals in the vapor track that could degrade or discolor the distillate.
Q: What is the expected lifespan of the vacuum seals under 24/7 operational cycles?
A: Under standard chemical processing conditions, our heavy-duty PTFE composite seals typically deliver 1,500 to 2,000 operating hours before requiring inspection or replacement. We include a complete backup sealing kit with every factory shipment to facilitate preventative maintenance.
Q: Can this unit be integrated into a continuous feeding setup?
A: Yes. As detailed in our workflow, the glass assembly includes a dedicated feeding valve tied to a PTFE injection tube, allowing operators to introduce new raw liquids into the rotating flask under vacuum without breaking the system's pressure state or stopping the rotation motor.
