CUNO Pleated Membrane Filter Cartridges & Capsules

Zetapor® membrane cartridges, composed of naturally hydrophilic Nylon 66, are available in charge-modified and uncharged formulations. Positively charge-modified Zetapor provides finer filtration than mechanical sieving at the rated pore size.

Zetapor Pharmaceutical Grade Cartridge

The Zetapor SP 0.45 mm pharmaceutical grade filter cartridges provide safe, reliable, and efficient operation. The Zetapor SP 045 has been validated for bacteria removal, and has passed the USP XXI Class VI Safety Test. The electropositive charge of the Zetapor membrane offers highly efficient filtration where removal to 0.45 µm is required. Because most particles are negatively charged, the positive charge throughout the Zetapor membrane matrix captures particles smaller than the rated pore size through electrokinetic adsorption.

BevAssure II Filter Cartridges

BevASSURE II filter cartridges incorporate CUNO’s new FlexN™ membrane technology that allows casting of an integral membrane onto a variety of substrates. The result is a microporous membrane with characteristics, such as increased flow and reduced pressure drop, tailored to provide ideal performance for the intended application. The new membrane technology is combined with a completely new cartridge design construction to provide enhanced mechanical and thermal resistance. This superior construction allows longer service life even under the most demanding process conditions and enables full use of the FlexN advantage.

LifeAssure PB Cartridge and Capsule Filters

LifeASSURE PB filter cartridges and capsules are CUNO’s latest advance in membrane filter technology. Encompassing two leading-edge processes, FlexN™ membrane manufacture and Advanced Pleat Technology™ (APT) pleating construction, the LifeASSURE PB series of filters offers unmatched protection of final membrane filters, as well as exceptionally long service life. Designed with pleated Nylon 66 membrane in an all-polypropylene cartridge construction, LifeASSURE PB filters are ideally suited for a wide range of prefiltration and clarification applications in the pharmaceutical, biological, and bioprocess industries.

Microfluor II Critical Sterilizing Grade PTFE Cartridge and Capsule Membrane Filters

Microfluor II membrane filters are available in 5 through 40 inch cartridges, 2.5 and 5 inch Mini Cartridges and 2.5, 5, 10, 20 and 30 inch capsules. With the exceptionally high Microfluor II flow rates, smaller and more economical assemblies can provide the same air flow as larger, more costly competitive PTFE filters. Microfluor II filters are optimized for applications requiring sterilization of air, gas, or aggressive solvents and chemicals. The hydrophobic PTFE filter membrane prevents wetting with aqueous liquids or moisture that can block free air flow. Some applications, however, may require filtration of aggressive fluids such as acids or bases. Depending on compatibility, Microfluor II filters can be used to provide sterile filtration of these fluids by prewetting the membrane with a low surface tension fluid such as alcohol.

Micro-Wynd II Blanket Media Filter Cartridges

The 3M Cuno Micro-Wynd II f blanket media filter cartridge is a major advance in blanketed filter technology. By combining an enhanced open wind process with an internal media blanket, the Micro-Wynd II provides superior flow rates, greater filtration efficiency, and consistent filtration characteristics from cartridge to cartridge, lot to lot. The superior performance is a direct result of the advanced winding pattern of the yarn matrix combined with CUNO’s exclusive patented process of separately applying a tailored media “blanket” between successive layers of yarn. This winding pattern creates much larger diamond shaped contaminant holding chambers. The separately inserted blanket encloses the chambers and maintains the consistency and integrity of filtration. These two factors combine to achieve a balance of filtration characteristics impossible to obtain with ordinary wound filter cartridges with teased or brushed up random fibers on the yarn to produce a filtering media.
