Membrane Filtration Unit – Alfa Laval LabStak™ M20‑0.72

General Description

The Alfa Laval LabStak™ M20‑0.72 is a flexible laboratory and pilot‑scale plate‑and‑frame membrane filtration unit designed for testing and development of cross‑flow membrane processes. It is intended for research, process optimization, membrane screening, quality assurance, and scale‑up studies. The unit supports RO, NF, UF, and MF flat‑sheet membranes and can optionally be configured for 2.5” spiral‑wound membranes, making it suitable for comparative membrane evaluations and process translation from lab to pilot scale.

Key Applications

• Membrane screening and benchmarking
• Concentration and diafiltration studies
• Process development and optimization
• Scale‑up data generation for industrial membrane processes
• Academic research and teaching laboratories
• Food, biotechnology, pharmaceutical, and water treatment R&D
