Advantec MFS Filtration Products Information

MEMBRANE FILTERS
  Membrane filters or "membranes" are polymer films with specific pore ratings. Membranes retain particles and microorganisms that exceed their pore ratings by acting as a physical barrier and capturing such particles on the surface of the membrane. 
  Advantec MFS membranes are manufactured in ISO 9001 certified facilities and certification is available upon request. 
  Advantec MFS membranes are available in a variety of polymers, pore sizes, diameters, and surface types. Most membranes can be sterilized by autoclaving. Click on each membrane type for more information:

PREFILTERS & DEPTH MEDIA
  Prefilters are often prepared from depth-type media, a random matrix of material which may or may not contain binder. These filters trap particles within the matrix and therefore have a high loading capacity. But because of this design, these filters do not have a clearly defined pore size, only a nominal rating. 
  These filters have applications outside of prefiltration, such as air and water pollution analysis, liquid clarification, and cell harvesting. 
  Advantec MFS prefilters are made of a variety of materials. Click on one of the following links for more information:

  If used as a prefilter, the filter should have a slightly smaller diameter than the filter membrane it precedes:
