20 L rotary evaporator for laboratories

The HNZXIB RE-2002 is a 20 L rotary evaporator designed for laboratory solvent recovery and concentration tasks. It operates on a 220 V supply and uses a 180 W motor with digital speed control from 0 to 120 r/min. A vertical double condenser provides 1 m² of cooling surface. The unit achieves an evaporation rate above 5 L/H for water at a vacuum degree of 0.098 Mpa.

Suited for high-volume batch processing.

This evaporator fits labs that need to process large batches with a 20 L evaporating flask and a 10 L receiving flask. The 5000 W water bath covers a temperature range of RT to 99 °C with an optional extension to 250 °C. Buyers who only handle small sample volumes or who require a 110 V supply without a 36 A circuit should look at smaller or differently powered models.

Handwheel or electric hoist lifting with PTFE

The water bath can be raised by handwheel or electric hoist, and the PTFE sealing system maintains vacuum integrity. The unit ships without a plug; an air switch must be provided on site. Installation also requires a circulating water vacuum pump for negative pressure and a refrigerator circulator for condensation, which are sold separately.

Questions about this item

Do I need a dedicated air-switch circuit before installing this 220 V rotary evaporator?

Yes, the unit ships without a plug and requires the buyer to provide an air-switch connection rated for 220 V 50 Hz supply.

Can I run the 5000 W water bath on the same 110 V line I use for smaller glassware?

At 110 V the evaporator would draw approximately 36 A, far exceeding a standard household circuit; 220 V operation is strongly advised.

Which reading on the digital display confirms the motor is turning at the set speed?

The display shows rotating speed from 0 to 120 r/min; when the value matches your setting the motor is running as intended.
