Rotary Evaporators

JP Selecta rotary evaporators enable efficient solvent evaporation under reduced pressure and controlled temperature, a fundamental technique in organic synthesis, extract purification, sample concentration and solvent recovery. The rotary evaporator requires a vacuum pump and a heating bath to complete the system.

The operating principle combines rotation of the evaporation flask, heating via a thermostated water bath, controlled vacuum and condensation in a refrigerated coil. Rotation generates a thin liquid film that multiplies the evaporation surface area, significantly reducing process time and the temperature required to evaporate the solvent. Flasks and coils are manufactured in borosilicate glass 3.3 per ISO 3585, which guarantees thermal shock resistance and chemical resistance to most organic solvents.

The range includes compact rotary evaporators for 1 to 5 litre volumes and professional systems with brushless motor, digital rotation speed control from 20 to 280 rpm, motorized flask lift and PID-controlled heating bath. Volumetric calibration of flasks follows ISO 4787 on laboratory glass and plastic ware - volumetric instruments, methods for testing of capacity and for use.

Applications cover evaporation of organic phases after liquid-liquid extraction in organic chemistry, concentration of natural extracts in pharmaceutical and cosmetic industries, solvent recovery for reuse, and solvent separation in analytical methods such as EPA SW-846 Method 3540C on Soxhlet extraction with rotary-evaporation concentration. For chemical nomenclature, see the IUPAC Blue Book and the Royal Society of Chemistry editorial resources.

Regarding regulatory compliance, JP Selecta rotary evaporators are aligned with the analytical instrument qualification principles of USP <1058> and with Good Manufacturing Practices for active pharmaceutical ingredients described in the ICH Q7 guideline, as well as with the general guidance on FDA process validation.

Manufactured in Abrera under ISO 9001:2015, ISO 14001:2015 and ISO 13485:2018 certifications, JP Selecta rotary evaporators include complete glassware kit, standard vacuum fittings, official technical service and guaranteed supply of replacement glassware.
