LabUnit M37/38
The Alfa Laval LabUnit M37/38 is a fully integrated plate-and-frame system for ultrafiltration and microfiltration membrane processes. The module of this unit utilizes the same support plates and membranes as our full-scale membrane filtration modules. This makes the Alfa Laval LabUnit M37/38 a flexible tool 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
Fully integrated system
The LabUnit M37/38 is a fully integrated desktop system comprising an Alfa Laval LabStak® M37/38 module, pump, pipework, valves and instrumentation.
The Alfa Laval LabUnit M37/38 offers the flexibility to simultaneously test up to 7 different membrane types. It can be fitted with the full range of Alfa Laval flat sheet membranes for ultrafiltration and microfiltration.
Option
For the Alfa Laval LabUnit M37/38 we offer plate sets with diffent channel heights to optimize flow and pressure:
- M37 plate set
For high viscosity liquids - M38H plate set
High channel, for medium viscosity liquids - M38L plate set
Low channel, for low viscosity liquids
Alfa Laval LabStak® M37/38
The Alfa Laval LabStak® M37/38 installed in the Alfa Laval LabUnit M37/38 is also available as a separate test unit for the same applications as the Alfa Laval LabUnit M37/38, and with the same distinct properties.

The feed stream/retentate flows through the open channels across the membrane surface in the plate-and-frame unit.
The membrane is supported by hollow plates with numerous slots that allow the permeate to be collected and removed from the unit via the permeate collecting tubes.
Plate-and-frame units use the membrane itself, aided by lock rings or strips, to seal off the feed/retentate and prevent any mixing with the permeate. This also prevents leaks from the plate stak itself.
