3M™ Zeta Plus™ LP Series Filter Cartridge, 4524401A 90LP, 12 in x 7.7 in, 9 Cell, Silicone, 2/CS

Zeta Plus LP Series filter media comprises a mixture of high surface area inorganic particles, cellulose, and a positively charged crosslinking polymer. This media is designed for relatively low organic extractable levels by aggressively extracting the cellulose fibers. The combination of filtration efficiency and throughput results from the balance between porosity, depth, and the relatively low level anion exchange capacity: removing some negatively charged soluble contaminants and sub-micron particles via anion exchange, and larger particles by mechanical sieving.

Pharmaceutical Grade Product

The Zeta Plus LP Series filter cartridges are designed for use in blood fractionation applications. The effluent characteristics of the Zeta Plus LP Series Filter media has been tested following a number of protocols contained in the United States Pharmacopeia (USP) compendia. The Zeta Plus LP Series filter media has a reduced potential of yielding false positives in product endotoxin testing resulting from 1,3 beta-glucan interference in LAL (Endotoxin) assays.

Product Design

The Zeta Plus LP Series filter cartridges are available with single layer media. Zeta Plus cartridges are constructed from individual cells of Zeta Plus LP series filter media bonded using molded edge seals. The cells are assembled together with polypropylene ring seals under predetermined compression and unitized by three, 316 stainless steel bands.

A full range of scalable filters enable predictable performance from laboratory to production. The BC25 laboratory capsule with 25 cm² filter media is designed for media grade screening using small liquid volumes. Filter cartridges and sanitary housings are available in 8 inch, 12 inch and 16 inch diameter, with surface areas ranging from 650 cm² to 3.9 m² per cartridge, enabling predictable scale-up and full scale production.
