50L rotary evaporator with a vertical double condenser, automatic lifting, and a stainless steel water bath for high-volume solvent recovery.
This equipment is sold for lawful use only. Buyer is responsible for compliance with all applicable regulations.
The Swiben D-R-1050 is a large-capacity rotary evaporator built around a 50L evaporating flask and paired 20L receiving flasks. It uses a vertical double condenser to expand the condensation surface area, supporting solvent recovery during distillation and concentration work.
The unit features a stainless steel water bath measuring φ550×320 mm, driven by a 6000W heater, and a brushless 250W rotary motor with digital frequency-conversion stepless speed control across 20–110 RPM. Automatic lifting moves the flask through a 0–180 mm stroke.
It is intended for high-throughput processing labs that require continuous evaporation of water- or alcohol-based mixtures and that can support the system with an appropriate chiller and vacuum pump.
The heated stainless steel water bath warms the rotating 50L flask while a vacuum is applied, lowering the boiling point of the solvent. Vapor rises into the vertical double condenser, where the increased surface area promotes condensation, and the recovered liquid collects in the 20L receiving flasks.
