At Dextrose Technologies Pvt. Ltd., we provide Rotary Evaporator (Rotavap) concentration to efficiently remove solvents and concentrate extracts under controlled conditions. Rotary evaporation is ideal for natural product research, bioactive fraction preparation, and pre-analytical workflows where you need gentle, efficient solvent removal before downstream testing (GCMS, LCMS, HPLC) or formulation steps. What we support Solvent removal from extracts and reaction mixtures Concentration of plant/microbial extracts and bioactive fractions Reduction of volume to improve handling, storage, and analytical readiness Support for solvent exchange (scope-dependent) Why rotary evaporation Concentration under reduced pressure helps lower effective boiling temperature Suitable for heat-sensitive samples when parameters are controlled Produces cleaner, manageable concentrates for repeat analysis Deliverables Concentrated extract (volume/format as agreed) Process notes (solvent, temperature range, vacuum conditions as applicable) Optional: guidance for storage and next-step analysis Get started Share your solvent type, starting volume, sample sensitivity, and target final volume/consistency. We’ll recommend the best rotavap settings and handover format.
