Applications of Multi Manifold Rotary Evaporator

Parallel Sample Concentration

Used for simultaneous concentration of multiple compatible small-volume liquid samples under the same general evaporation workflow.

Laboratory Sample Preparation

Supports evaporation of multiple laboratory solutions and extracts before subsequent testing or processing.

Small-Batch R&D

Useful when several formulation, reaction or extraction samples need to be processed under comparable conditions.

Powder Drying

Intermittent forward/reverse rotation supports compatible powders and solid samples during reduced-pressure drying.

FAQ

The system can process up to five samples simultaneously. DW-2000ADQ supports 5 × 50 mL, DW-3000ADQ supports 5 × 100 mL, and DW-5000ADQ supports 5 × 150 mL.

Yes. It supports both multi-flask and single-flask operation. The single-flask ranges are 25–2000 mL, 25–3000 mL and 25–5000 mL, depending on the model.

The rotation speed is adjustable from 0 to 310 rpm. For DW-5000ADQ, the brochure specifies up to 310 rpm when using an inner rotating flask up to 3 L.

The water bath operates from room temperature to 99°C ±0.5°C with microcomputer PID temperature control.

Yes. The forward and reverse rotation interval can be adjusted from 0 to 60 seconds for compatible powder-drying workflows.

Yes. A Vacuum Control configuration is available with a built-in vacuum controller.

The built-in vacuum controller provides a setting range of 0–1013 mbar with a specified accuracy of ±1.
