EziLab supplies the Rotary Evaporator EZL-RE26 for pharmaceutical laboratories that need pilot-scale solvent evaporation beyond standard bench-scale glassware capacity. With a 20L flask, 0-110rpm rotation, and 5kW heating, this laboratory evaporator removes solvent from larger sample batches by rotating a flask under vacuum while applying heat, increasing the liquid's surface area to accelerate evaporation compared to static distillation methods. That 20L flask capacity puts this unit firmly in pilot-scale territory, well beyond the smaller flask sizes typical bench-top rotary evaporators use, suited to pharmaceutical process development scaling up from lab-bench formulation work toward production-relevant batch sizes before committing to full manufacturing scale. The 5kW heating capacity drives evaporation across that larger flask volume at a practical rate, since a bigger liquid volume needs proportionally more heat input to maintain efficient evaporation than a small bench-scale flask would require. The 0-110rpm rotation range creates the thin liquid film against the flask wall that maximizes surface area for evaporation, adjustable to match different solvent viscosities and flask loading levels. Pharmaceutical process development labs scaling formulation or extraction work toward production volumes get pilot-scale evaporation capacity here rather than running multiple smaller bench-scale batches. See the Laboratory Evaporator and Rotary Evaporator ranges for pilot-scale solvent evaporation needs across USA pharmaceutical laboratory settings.
