Membrane filter material Membrane filtration is one of the methods of sterilization when heat sterilization cannot be performed. As sizes of bacteria ranges from 0.3μm to 0.5μm, pore size of a sterile membrane filter is generally 0.2μm, as it is suitable for removing contaminating microorganisms.
Advantec MFS. the filtration area of a 47mm diameter filter (9.6cm 2 ). Membranes are sterilized by ethylene oxide (EtO) gas and are available individually wrapped or in 10-pack envelopes. Membrane specifications and lot number are printed on clear cover of each filter. Advantec's continuous pleated band.
This technique can be used for most membrane filters with a single refractive index. The refractive index for Durapore membrane is 1.42 and for MF membrane its 1.50. Please note that this does not work for polycarbonate membranes because these membranes have more than one refractive index (1.62 and 1.58). If desired, the porous structure can be
May 1, 2022 · For applications where reliability is critical, we give filter makers what they expect from a membrane supplier without compromises to retention and flow or quality. Our high retention and flow rate membrane assures repeatable high performance, consistent quality and exceptional high cleanliness.
Whatman™ Glass Microfiber Prefilters are designed with a coarse glass filter top layer (10μm) meshed with a finer layer. The multigrade glass filter traps larger particles in its pores of the coarse layer, medium-sized particles in the interface meshing, and smaller particles in the interstices of the fine layer. 27.
The hydrophilic cellulose acetate membrane filters combine high flow rates, good chemical resistance (pH 4-8) and thermal stability with very low adsorption characteristics. They are excellently suited for use in pressure filtration devices.
Millipore ® PVC membrane filters are produced from high-quality PVC and have been developed for use with ASTM, NIOSH, and OSHA air monitoring methods. Alumina oxide membrane filters are non-toxic and compatible with most solvents and aqueous solutions.

Membrane filtration is one of the most effective separation processes and is steadily under development leading to new prospects. Sartorius membranes are available in a wide variety of pore sizes and structures — as well as surface properties — to serve nearly unlimited selectivity of separation.
Membrane filters serve as effective physical barriers that remove solids, viruses, bacteria, and other unwanted molecules. Specialized types are designed for softening, disinfecting, organic removal processing, and water desalination. The filters can be installed in compact, automated, or modular units.
Prefiltration: Prefiltration utilizes large pore membrane filters to remove large particulates, such as dirt or sediment, from samples prior to filtration with a smaller pore membrane filter. Using prefiltration in sample preparation can prevent premature filter clogging or fouling.
Polycarbonate Transwell inserts feature thin, translucent membranes available in four pore sizes ranging from 0.4 µm to 8.0 µm. Most are treated for optimal cell attachment. They are supplied sterile and come preloaded in multiple well plates or dishes. The polycarbonate membrane is compatible with most organic fixatives and stains.
Principles of Filtration. Membrane filtration is a rapidly developing science, characterized by intrinsic terminology and proprietary information. In order to better serve the diverse and expanding needs of our customers and establish a mutual understanding, we at Sterlitech Corporation have compiled this accessible reference of the basic
