0.22 Micron Filter Cartridge Supplier in India

A pleated membrane element rated at 0.22 micron, built into a standard cartridge envelope with end caps that seat into a matching housing. It is used for fine particulate reduction and for critical-filtration workflows where a very tight rating is required, and it is supplied in several membrane materials — PES, hydrophobic and hydrophilic PTFE, Nylon and other pleated media.

The rating describes how the manufacturer designates that membrane, correlated to its own retention testing. It is not a measured universal aperture, and it does not by itself describe what the filter is qualified to do. Two cartridges both marked 0.22 micron in different materials are built for different duties and are not interchangeable.

No. Sterilizing-grade is a designation a manufacturer earns for a specific product by challenging that filter with bacteria — conventionally Brevundimonas diminuta at a defined loading per unit of filter area, by the method described in ASTM F838 — and demonstrating sterile effluent under stated conditions of fluid, flow, pressure and time.

A cartridge that has not been through that programme is a 0.22 micron filter and nothing more. Where a sterilizing duty is genuinely required, the specification is a named product with a validation guide, a documented integrity-test method and limits, and approval by your QA and validation function. Where the duty is particulate reduction or clarification, a 0.22 micron cartridge is often exactly right and none of that is needed.

The membrane material, and therefore what each is built to do. PES is naturally hydrophilic and is commonly specified for aqueous, pharmaceutical and biotech liquid duty where throughput matters. Hydrophobic PTFE repels water and is used for air, gas and tank-vent duty. Hydrophilic PTFE is surface-modified to pass liquid while keeping PTFE's chemical resistance, so it suits solvents, acids and alkalis. Nylon is broadly compatible across aqueous and many organic fluids and is naturally wettable.

Beyond compatibility, the material governs wetting behaviour, flow for a given pressure drop, protein and analyte binding and extractables behaviour. Because the rating is the same across all of them, the material is effectively the whole selection — and confirming compatibility against the full cartridge construction matters, since supports, cage, core, end caps and seals are frequently a different polymer from the membrane.

Hydrophobic PTFE, because a vent has to keep passing gas in service that is often humid or condensing, and a wettable membrane would block as soon as condensate reached it.

Sizing matters more than on most cartridges. A vent must pass gas at least as fast as liquid leaves the vessel, or the tank goes into vacuum — and tanks are considerably weaker in vacuum than in pressure. Size on the fastest transfer rate the vessel will see plus any steam or CIP flow, not on tank volume. In condensing service a heated or jacketed housing keeps the membrane dry, and the element should be dried after steam sterilisation before the vessel returns to transfer duty.

Usually hydrophilic PTFE, and in some duties Nylon, where the selected product is designed and documented for that fluid. Hydrophilic PTFE wets with liquid while retaining the chemical resistance that made PTFE the choice, which is what suits it to solvents, acids, alkalis and reagents.

Confirm compatibility against the whole cartridge rather than the membrane alone. Support layers, cage, core, end caps and O-rings are usually polypropylene or another polymer, and on aggressive chemistry those commonly reach their limit before the membrane does — the seal material in particular is frequently the weakest component and the easiest to specify wrongly. Where the fluid is the product and trace contamination matters, ask for extractables information as well as a compatibility chart.

They describe how the cartridge seals into the housing. DOE — double open end — is a plain element sealed by compression between plates. Code 7 has a 226 O-ring at one end with a bayonet lock and a fin or spear at the other, positively locating the element so it cannot lift or bypass under flow or a pressure surge. Code 3 uses a 222 O-ring with a flat end.

The codes are not interchangeable, and a Code 7 element will not seat in a Code 3 or DOE housing. Where a defined retention is the point, positive O-ring retention is normally specified, because a compression seal that relaxes leaves a bypass path around the membrane and the rating then means nothing. Confirm the code, and the seal material, against the housing before ordering.

A non-destructive measurement on the installed filter, correlated by the manufacturer to the retention testing performed on that product, confirming the membrane and its seals are intact and that the assembly matches the condition the data applies to.

A wetted hydrophilic filter is generally tested by bubble point, diffusion or pressure hold. A hydrophobic filter cannot be water-wetted the same way, so hydrophobic elements are commonly tested by a water intrusion method or an alcohol-based wetting procedure, depending on the product. Both the method and its limits are product-specific and must come from that item's own guide rather than from a general figure. An integrity test confirms the filter is sound; it does not by itself establish that your process is validated.

Datasheets, validation guides, integrity-test guidance, chemical compatibility information, extractables or biological-safety documentation and Certificates of Analysis can be coordinated where the relevant manufacturer issues them for the specific product.

They are not available for every product or brand, and their scope differs considerably. State what your file needs at enquiry — particularly whether a validation guide is required, since that narrows the product list immediately — and availability can be confirmed for the specific item before an order is placed. ScientificEdge supplies this documentation where it exists and does not itself validate, test or certify any of it.

Sourcing enquiries are supported for reputed brands including Sartorius, Pall, Merck Millipore, Parker domnick hunter, Cobetter and Graver, along with equivalent options, subject to availability, technical compatibility, documentation and buyer requirement.

This does not indicate authorised distribution, official dealership or an exclusive partnership with any brand. An equivalent is matched on membrane material, pore rating and how that rating is defined, full materials of construction, dimensions, end-cap code and seal material. Where the step is a validated one, substituting a filter is a change to a qualified arrangement, so whether an equivalent is acceptable is your QA or validation function's determination rather than a sourcing question.

Yes. Supply and project coordination run from Delhi NCR across Gujarat, Maharashtra, Tamil Nadu, Telangana, Karnataka, West Bengal and other industrial and pharmaceutical clusters, covering production, pilot, laboratory and institutional requirements.

Cartridges are supplied individually packaged and should be stored sealed, clean and dry within the temperature range the manufacturer states. Lead time is confirmed per line item at quotation stage; commonly held materials and lengths move quickly, while specific brands, capsule formats and documented product lines are often imported to order — worth allowing for if the element is on a qualified list.
