Wiped Film Evaporation Equipment-Glass Wiped Film Evaporator-Anvore Scientific-Lab & Industrial Process Equipment

The AV-B200 pairs a 200 mm inner-diameter borosilicate-glass evaporation column with 0.35 m² of evaporation area and 0.55 m² of condensation area — a format purpose-built for pilot-to-production campaigns. The 240 W wiper drive (up to 450 rpm) spreads feed into a sub-0.5 mm film on the heated wall, while the internal condenser, cold well, external condenser and cooling unit capture volatile fractions with high efficiency. Deep-vacuum operation (standard <10 Pa; ~0.1 Pa with optional molecular or diffusion pump) keeps distillation temperatures far below normal boiling points, protecting heat-sensitive and easily oxidized products. With a 5 L feed vessel, 5 L light- and heavy-fraction receivers, and throughput up to 15 L/h, the AV-B200 bridges the gap between laboratory trials and full production for fine chemicals, pharmaceuticals, food, essential oils and petrochemical processing. CE- and ISO-certified; 220 V / 110 V compatible.

Key Advantages — and Why They Matter

Advantage	Why It Matters
Distillation far below normal boiling points	Protects high-boiling, heat-sensitive and easily oxidized compounds that conventional stills would degrade.
Residence time of only seconds	Minimal thermal exposure preserves product integrity, color and potency.
Ultra-high vacuum (<10 Pa standard; ~0.1 Pa optional)	Lower operating pressure means lower distillation temperature and cleaner cuts between components.
Liquid film thinner than 0.5 mm	Outstanding heat-transfer efficiency and evaporation rate, even for viscous feeds.
No boiling or foaming	Free-surface evaporation without entrainment — no product carry-over, no bumping.
Selective multi-stage separation	Two or more components can be isolated in a single pass train; excellent for de-solventizing extracts.
PTFE / SS316L wiper system	Extreme corrosion resistance for aggressive solvents, acids and chlorinated media.
All-glass process path	Full visual control of film formation, wiper action and condensation during process development.
Physical, additive-free separation	Non-toxic, pollution-free and residue-free — ideal for food, pharma and nutraceutical purity requirements.
Customizable capacities and sizes	Feed and receiver volumes, heating and vacuum options can be matched to your process.

Working Principle

Step 1. Feeding — the feed liquid enters the top of the vertical glass evaporation column (optionally pre-heated in the feed tank).
Step 2. Film formation — the rotating PTFE / SS316L wiper blades spread the liquid into a turbulent film thinner than 0.5 mm on the heated inner wall.
Step 3. Evaporation — under deep vacuum, volatile components vaporize from the film surface at temperatures far below their atmospheric boiling points.
Step 4. Condensation — vapor travels a short distance to the internal condenser (0.55 m²) and cold well, is chilled by the cooling unit, and collects as the light fraction.
Step 5. Residue discharge — non-volatile material flows down the wall into the heavy-fraction receiver, or is pumped out by an optional gear pump.
Step 6. Separation control — stage temperature, vacuum and feed rate are tuned to select the desired cut; multiple stages can separate two or more products.
