Advantec A045F047W Membrane Filters MCE 0.45 WG W/PAD IND 47MM 1000/PK

Advantec A045F047W membrane filters are commonly used for microbiological analysis and particle retention in laboratory samples. They are frequently applied in testing water, wastewater, food, beverages, and pharmaceutical samples where microorganisms or fine particles need to be captured on the membrane surface.

These filters are made from mixed cellulose esters (MCE), typically a blend of cellulose nitrate and cellulose acetate. This membrane material offers high porosity, good flow rates, and reliable particle retention, making it suitable for many general laboratory filtration applications.

A 0.45-micron pore size is widely used for microbiological testing because it can retain many bacteria and fine particles while allowing liquids to pass through efficiently. This pore size is commonly used in membrane filtration techniques for water quality and environmental analysis.

The grid pattern printed on the membrane surface helps researchers easily count microbial colonies during analysis. The absorbent pad placed beneath the membrane holds growth media or broth, helping maintain moisture and supporting microbial growth during incubation.

The 47 mm diameter format is one of the most common sizes used in laboratory membrane filtration systems. These filters typically fit standard vacuum filtration assemblies, manifold systems, and microbiological testing equipment designed for 47 mm membrane discs.
