Rotary evaporator RE-2000A

Overview

The Rotary evaporator RE-2000A is a laboratory distillation system designed for the controlled removal of solvents under rotation and heat. It is configured with a 2 l rotating flask plus a 1 l flask and a 1 l receiving flask, providing a practical setup for routine evaporation work. A range of alternative rotating flasks is supported, including 0.1 L, 0.25 L and 0.5 L sizes, allowing the system to be adapted to different sample volumes. The unit features automatic lifting, so the flask can be raised and lowered from the heating bath without manual handling, and a vertical type condenser for efficient vapour condensation.

Technical Specifications

• Rotating flask: 2 l + 1 l
• Optional rotation flasks: 0.1 L, 0.25 L, 0.5 L
• Receiving flask: 1 L
• Lifting type: automatic lifting
• Condenser: vertical type
• Rotation speed: 20–200 rpm
• Evaporation speed (alcohol): 1.2 L/h
• Evaporation rate (water): 25 mL/min
• Bath power: 1.5 KW
• Temperature and wave control range: RT–180 ℃ & 2 ℃
• Standard power: 220 V 50/60 Hz, single-phase

Performance and Operation

The rotation speed is adjustable across a 20–200 rpm range, helping to maintain a consistent thin film of liquid on the flask wall and to support a steady evaporation process. The heating bath delivers 1.5 KW of power and operates from room temperature up to 180 ℃, with a control resolution noted at 2 ℃. Under the stated conditions, the system reaches an evaporation speed of 1.2 L/h for alcohol and an evaporation rate of 25 mL/min for water. The single-phase 220 V 50/60 Hz supply makes the unit straightforward to integrate into standard laboratory infrastructure.

Applications

This rotary evaporator is especially used for standard distillation, crystallization, product concentration, powder drying and single-solvent separation. It can also be applied to sample pretreatment for gas, liquid and mass spectrometric analysis. As an essential basic tool for production and analytical testing, it serves concentration, drying and recovery tasks across the chemical industry, the medical industry, universities and research laboratories. Laboratories that perform larger-scale processing alongside evaporation often pair such a system with a glass reactor for natural product extraction, creating a complementary workflow from reaction to concentration.

For facilities comparing models or seeking an additional unit dedicated to solvent removal, the RE-2000A offers a balanced combination of flask capacity, adjustable rotation and a wide temperature control range. Its automatic lifting and vertical condenser support repeatable, hands-off operation, making it well suited to both production environments and analytical testing routines.
