20 L Rotary Evaporator for Lab Crystallisation

The RE-2002 is a 20 L rotary evaporator designed for material crystallisation and separation in laboratory settings. It operates on 110 V mains power and includes a water bath lifting mechanism for convenient flask handling. The system suits chemists and process engineers who need continuous solvent recovery at moderate scale. Its vertical condenser and PTFE sealing system support reliable vacuum performance.

Upgrades from Smaller Benchtop Rotavaps

Laboratories moving up from 5 L or 10 L units gain a 20 L evaporating flask and a 10 L receiving flask, reducing the number of batch cycles for the same throughput. The jump is worth it when daily solvent volumes exceed the capacity of smaller flasks and when the 5 L per hour water evaporation rate matches the workflow. The digital speed control up to 120 r/min and vacuum degree of 0.098 M pa provide the process control needed for scale-up.

Sustained Operation with Water Bath Lifting

Under continuous load the 4000 W heating power and 5000 W water bath maintain a stable temperature range up to 99 °C with ±1 °C fluctuation. The motor delivers 180 W for steady rotation during long runs, while the 1 m² condenser cooling surface handles vapour load without flooding. Wooden case packaging protects the glassware during transit, and the PTFE seals resist chemical attack over extended use.

Questions about this item

What clearance and power supply does the 20 L evaporating flask and water-bath lifting mechanism require?

The unit runs on 110 V / 60 Hz with a 4000 W heating element and a 5000 W water-bath lift, so a dedicated 110 V circuit rated for the combined load is needed; allow enough bench height for the vertical condenser and lifting travel.

Which connections must be made before the first run, and which step is most often missed?

Connect the US plug to 110 V, attach the 20 L evaporating flask and 10 L receiving flask, fit the PTFE sealing system, hook up the condenser cooling water, and link the vacuum pump to reach 0.098 Mpa; users frequently forget to verify the vacuum seal before heating.

What consumables or parts will need replacement after extended use?

The PTFE seals and vacuum pump oil will wear; the 180 W motor and 120 r/min drive are rated for continuous duty, but plan to inspect seals and pump oil regularly to maintain the 0.098 Mpa vacuum and >5 L/H evaporation rate.
