LabUnit M10

With a membrane area of only 336 cm² the Alfa Laval LabUnit M10 is the smallest and most compact of the cross-flow membrane filtration plants offered by Alfa Laval for ultrafiltration and microfiltration. It is a fully integrated system and a popular choice for educational purposes and research and development work

Fully integrated system

The Alfa Laval LabUnit M10 is an extremely versatile, yet easy to use, unit for process development and optimization, scale-up as well as training purposes. The flexibility to install and test two different membranes simultaneously makes it an efficient tool for initial membrane selection.

The Alfa Laval LabUnit M10 can be used with the complete range of flat sheet membranes offered by Alfa Laval for ultrafiltration and microfiltration.

  • fully integrated yet flexible system comprising an Alfa Laval LabStak® M10 complete with necessary pump, pipework, valves, heat exchanger and instrumentation
  • easy exchange of membranes
  • transparent plate for observation of cross-flow
  • simultaneous test of two different membrane types
  • high operating temperature (80°C)
  • small test media volume
  • flow pattern similar to that of larger modules
  • all components in compliance with FDA and EEC regulations, allowing use within food and pharmaceutical processing applications

How it works

The feed stream/retentate flows through the open channels across the membrane surface in the plate-and-frame unit called LabStakTM M10 module.

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.
