MMS Membrane System SW18 Batch Membrane Filtration Unit for Ultrafiltration and Nanofiltration

The MMS Membrane System SW18 is a versatile batch laboratory membrane filtration system designed for precise microfiltration, ultrafiltration, nanofiltration, and reverse osmosis processes. Developed for applications including molecular fractionation, purification, and concentration, this bench-scale unit supports testing of spiral wound, ceramic, hollow fiber, and tubular membrane modules with operating pressures up to 40 bar.

Key technical features include:

• Speed-controlled pressure and circulation pumps with Clean-In-Place (CIP) and Steam-In-Place (SIP) capabilities, ensuring accurate process control critical in bioprocessing and molecular diagnostics workflows.
• A multitube heat exchanger allowing temperature regulation essential for maintaining membrane integrity during filtration tests.
• An intuitive HMI touch panel with data logging for process monitoring and parameter adjustment, suitable for research in synthetic biology and biomanufacturing.
• Membrane area of 0.3 m² using a spiral wound 1812 module, with compatibility for a broad range of membrane types.
• Robust construction with all tubing and fittings made from 316L stainless steel and a 10 L stainless steel feed tank, supporting biotechnological applications requiring high-purity systems.
• Operating dimensions of 1020 x 600 x 850 mm and weighing 100 kg, compatible with benchtop laboratory setups.

The unit provides permeate flow rates from 1 to 5 L/h, depending on feed characteristics, and total flow rates up to 450 L/h. It incorporates high-precision instrumentation including two pressure transducers (0–50 bar), a temperature transducer (0–100 °C), and a balance with 1 g resolution, enabling detailed membrane performance analysis in clinical diagnostics, biofuels processing, and food extract purification.

Widely adopted across sectors such as biotechnology, chemical processing, and food and aroma extraction, the MMS SW18 supports critical procedures in protein concentration, acid recovery, and organic acid clarification, making it an essential apparatus for research laboratories focused on membrane technology and bioprocess development.
