EziLab Automatic Rotary Evaporator EZL-RE33 handles larger batches with a 3L rotating bottle and 2L receiving bottle for laboratory distillation workflows across pharmaceutical, chemical, and biological environments. Rotation speed runs from 0–200 rpm for stable evaporation control, while bath temperature range covers 0–99°C with 1°C variation via PT100 sensing. Achievable vacuum reaches 0.098 MPa for low-pressure solvent removal, and motorized elevating provides 150 mm lift for safe flask movement. Double Teflon sealing helps maintain vacuum stability during runs, with heating power of 2 kW for faster bath recovery. Suited to evaporation, concentration, crystallization, separation, and solvent recovery in pharmaceutical, chemical, and biological research via Lab Equipment and EziLab's full range of laboratory evaporators for lab workflow integration.
