2L BVV Electric Lift Rotary Evaporator

A 2L Rotary Evaporator Sized for One Bench Solvent recovery at small scale is where this unit sits. The evaporating flask holds 2L and the receiving flask holds 1L. Rotation runs from 20 to 198 RPM under digital step-less regulation. The bath is Teflon composite, measures 10 x 5 in, and sets anywhere from 0 to 99 C. Heater draw peaks at 13.6 A on 110V, with total consumption of 1.8 kW. Pulled against a suitable pump the system reaches -29.8 inHg. BVV rate alcohol recovery at one litre per hour or better. All glass is GG-17 high borosilicate and the condenser is a vertical double helix. Valves are PTFE throughout, which matters more than it sounds. Rubber and PTFE age very differently against warm ethanol. Where the Electric Lift Rotovap Saves You Trouble The motorised lift is the part that changes daily use. Budget units use a hand crank, and raising a loaded flask out of a hot bath by hand is how glass gets broken. Here the stroke is powered across 14 cm, so the flask comes up level and under control. Direct injection lets you feed solution continuously instead of stopping to recharge the flask. That is what turns a batch process into something closer to a run. The footprint stays inside 28 x 18 x 27 in and the whole unit weighs 82 lb assembled. The unit carries a CE listing. Warranty runs 90 days and excludes glassware, consumables and moving parts, which is worth reading twice before you stock spares. Glass is the consumable on any rotovap, and this one is no exception.
