alpha plan has the technology of hollow fiber module manufacture.

Technology

Alpha Plan specializes in the development and manufacture of single-use filter modules suitable for various applications such as in the medical and biotechnology industries. Based on our many years of experience in membrane filtration and separation, we understand the needs of our customers and know how to develop customized product solutions.

On the one hand, we have a wide range of filter membranes, housings and individual connections, but on the other hand, we can also develop customized solutions for practically any single-use membrane application in collaboration with our customers.

Overview of common pore sizes and their suitable separation process

Membrane

The heart of every filtration module is the membrane with its defined separation properties. Depending on the substances to be separated, different types of membrane filters can be used.

In general, Alpha Plan offers individual filter solutions for the Ultrafiltration and microfiltration range to.

Flat membrane
  • Single-layer or multi-layer membrane packages available
  • Different membrane types for ultrafiltration or microfiltration
  • PC or PET membrane

We offer a range of standard diaphragm types with different properties:

  • Geometric dimension
  • Membrane separation limit / pore size
  • Filtration performance
  • Compressive strength
  • Biocompatibility

Housing

The requirements for the housing design and housing material vary greatly depending on the individual application. E.g. flow rate, operating pressure, filter surface, but also chemical resistance or sterility requirements.

We offer a wide range of standard module housings and can develop customized modules if required.

Connections

The hollow fiber modules are each equipped with 2 extra and intracapillary connections that allow access to both sides of the membrane.

Standard connections are either Luer Lock or hose barb connections. On request, we can integrate additional ports or use different components (e.g. Hansen or John Guest connections).

Alpha Plan membrane filtration modules give you the opportunity to improve process efficiency and economy, with super performance and consistent quality at the highest level.
