Pilot Scale Solvent Evaporation

The Pilot Scale Digital Control Rotary Evaporator (RE500-E) is a pilot-scale, digital distillation system designed for efficient and gentle removal of solvents from samples by evaporation under reduced pressure for pilot production and biopharmaceutical manufacturing . Featuring a 5L evaporating flask capacity, 2.0 L/h evaporation rate (75% alcohol), and 2000W heating power (water bath 20-100°C / oil bath 20-180°C optional), this pilot-scale unit provides precise temperature control (PID control, water bath: ±1°C), rotation speed (20-180 rpm), and timer (0-999 minutes) control for large-volume processing .

Key features include a large LCD digital display for real-time monitoring of temperature, speed, direction, and time; stepless automatic motorized lift with 130mm stroke for smooth and silent operation; and a double-layer high-efficiency condenser with large cooling surface area and anti-backflow design for high-efficiency sample recovery . The heating bath features switchable water/oil heating modes, Teflon-coated inner layer for corrosion resistance and easy cleaning, and special insulation design that keeps outer surface temperature low to avoid operator burns . The professional PTFE sealing system provides high temperature resistance, corrosion resistance, and durability for extended service life . The automatic switching valve enables continuous collection of distillate without compromising system vacuum or solvent distillation, significantly increasing throughput for industrial applications .

For the bioprocess engineer and pharmaceutical manufacturing scientist, the Pilot Scale Digital Control Rotary Evaporator (RE500-E) supports large-scale concentration of bioreactor harvests, purification of bulk active pharmaceutical ingredients (APIs), solvent recovery from pilot production runs, pilot-scale natural product extraction for nutraceutical manufacturing, high-volume solvent recovery for waste reduction, and pilot-scale concentration for cosmetics and food industry production . Safety features include motor overcurrent protection, earth leakage protection, lift overload protection, anti-dry burning protection, over-temperature protection, and automatic lift stop on power failure .

Continuous feeding capability, digital steam temperature sensing device (real-time feedback of solvent steam temperature for adjusting appropriate vacuum degree), forward and reverse rotation function (suitable for concentration of samples containing powder or solid particles), and optional vacuum controller for automated solvent separation ensure versatile, efficient operation for industrial manufacturing . With a compact footprint (600 × 290 × 720mm)  and pilot-scale capacity, the Pilot Scale Digital Control Rotary Evaporator (RE500-E) is an essential instrument for pharmaceutical manufacturing, bioprocessing, chemical production, cosmetics manufacturing, food industry quality control, and pilot plant operations .
