Short Path Molecular Distillation Unit-Short Path Molecular Distillation System — Glass-Anvore Scientific-Lab & Industrial Process Equipment

The AV-F80 is a short-path molecular distillation apparatus built around a Ø 80 mm borosilicate glass evaporator body with 0.1 m² of evaporation area and 0.15 m² of condensation area. Doubling the throughput of bench-top models, it processes 0.5–4.0 L/h in a compact footprint — the ideal bridge between small-scale feasibility studies and pilot production.

Molecular distillation is a special liquid–liquid separation technology: under high vacuum (below 10 Pa), the mean free path of vapor molecules exceeds the distance between the evaporation and condensation surfaces, so components are separated by their differences in evaporation rate — not by boiling. A 120 W PTFE / 304 SS wiper system (up to 450 rpm) spreads the feed into a turbulent film thinner than 0.5 mm on the heated wall (RT–200 °C); light components evaporate and condense on the internal condenser, while heavy components flow to a separate 1 L receiver. A built-in cold trap protects the vacuum pump, and an external condenser is available as an option.

Compared with conventional short-path stills, the AV-F80 delivers shorter residence time, lower processing temperature and continuous operation without breaking vacuum — a true plug-and-play, turn-key solution for lab and pilot purification of high-boiling, heat-sensitive and easily oxidized materials.

Key Advantages

Gentle Low-Temperature Separation — Operates far below the boiling point with a short residence time — ideal for high-boiling, heat-sensitive and easily oxidized materials.
High Vacuum, Below 10 Pa — Ultimate vacuum below 10 Pa (no-load) protects materials from oxidation and lowers the operating temperature.
Thin Film, High Heat Transfer — Wipers spread the liquid into a film < 0.5 mm thick, giving high evaporation efficiency with no bubbling or foaming.
Pilot-Grade Throughput — 0.5–4.0 L/h with 1 L feed vessel and 1 L light / heavy receivers (all customizable) — twice the capacity of bench-top models.
Effective Degassing & Deodorizing — Efficiently strips organic solvents and odors — highly effective for desolvating solvent-extracted liquids.
Multi-Stage Selective Separation — Selectively evaporates target products and removes impurities; multi-stage operation separates 2+ components simultaneously.
Corrosion-Resistant Wetted Parts — Wiper system of PTFE + 304 stainless steel; fluoroelastomer (optionally PTFE) gaskets throughout for excellent sealing and chemical resistance.
Cold Trap Standard, Options Galore — Built-in cold trap and cooling device; optional external condenser, preheatable feed vessel and custom receiver sizes.
Pure Physical Separation — Non-toxic, harmless, pollution-free and residue-free — yields clean, safe products with no solvent carry-over.
