LabStak M37/38

The Alfa Laval LabStak® M37/38 is a flexible plate-and-frame test unit for ultrafiltration and microfiltration membrane processes. The unit utilizes support plates and flat sheet membranes of the same size as our full-scale membrane filtration modules. This makes the Alfa Laval LabStak® M37/38 a popular choice for process development, up-scaling, membrane testing, quality assurance and small-scale production. Optional plate sets are available for feeds of different viscosity / solids content
