EziLab Automatic Rotary Evaporator EZL-RE35 handles concentration tasks using a 5L rotating bottle and a 3L collecting bottle for laboratory distillation workflows across pharmaceutical, chemical, and biological environments. Rotation speed range is 10–140 rpm for controlled evaporation behavior, with evaporation capability reaching 2 L/h for water and 6.5 L/h for alcohol. Achievable vacuum reaches 0.098 MPa for low-pressure operation, and bath temperature range covers 0–399°C with 1°C variation on an LCD. Automatic elevating provides 150 mm stroke for convenient flask adjustments, and double PTFE sealing helps maintain vacuum stability during solvent recovery. Suited to evaporation, concentration, crystallization, separation, and solvent recovery in pharmaceutical, chemical, and biological laboratories via Lab Equipment and EziLab's full range of laboratory evaporators for lab workflow integration.
