PES Membrane Filter Cartridge Supplier in India

A filtration element built from polyethersulfone membrane, pleated to pack a large membrane area into a standard cartridge envelope and fitted with end caps that seat into a matching housing. PES is hydrophilic, so it wets out with water without needing an alcohol pre-wet, which is one reason it is widely used for aqueous and process-liquid duty.

It is a surface filter with a defined pore rating rather than a depth filter that holds dirt economically. That distinction drives how it is used: a membrane cartridge is specified where a defined retention is the requirement, and it is normally protected by a separate pre-filter that carries the bulk particulate load.

Pore rating, and therefore what each is used for. A 0.45 micron membrane is generally applied to bioburden reduction, clarification and pre-filtration duty. A 0.22 micron membrane is the rating conventionally associated with sterile filtration workflows, where the selected product is validated for that application.

They are frequently used together rather than as alternatives — a 0.45 stage ahead of a 0.22 carries the bulk load and extends the life of the finer membrane considerably. Going straight to 0.22 on an unprotected stream is possible and usually expensive, because the finer membrane blinds on particulate a coarser one would have taken out. Which rating is appropriate follows from the process requirement and the microbial-control strategy, and the sterilizing-grade designation belongs to a specific validated product rather than to the 0.22 rating in general.

Aqueous and process liquids across pharmaceutical, biotech, diagnostics, food and beverage, fine chemical, electronics and laboratory workflows — buffers, media, biological solutions, reagents, process water, product streams and high-value liquids among them. Low non-specific binding makes PES a common choice where the value is in the liquid rather than in what is removed from it.

Suitability for any specific duty depends on chemical compatibility with your fluid at your temperature, the operating and sterilization limits of the particular product, and — on regulated processes — the validation your QA function requires. It should not be assumed from the material alone, and PES should not be specified for Water for Injection production, injectable final filtration, sterile drug manufacture or vaccine processing unless the product documentation and your own validation requirements confirm it.

They describe how the cartridge seals into the housing. DOE — double open end — is a plain element sealed by compression between plates, simple and inexpensive. 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 cartridge 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: a Code 7 cartridge will not seat in a Code 3 or a DOE housing. For membrane filtration where a defined retention is the point, positive O-ring retention is normally specified, because a compression seal that relaxes gives a bypass path around the membrane and the rating then means nothing. Confirm the code against the housing before ordering rather than after.

PES membrane cartridges are widely used in pharmaceutical and biotech processing, but whether a particular filter is suitable for a particular pharmaceutical application is a product-specific and process-specific question rather than a material one.

Where the duty requires sterilizing-grade filtration, the manufacturer's validation establishes what the product is capable of under its stated test conditions, and your own validation establishes that it performs in your fluid, at your process conditions, for your process time. Extractables data, biological-safety information, sterilization limits and integrity-test values all come from that specific product's documentation. ScientificEdge coordinates and supplies that documentation where it exists; the determination of suitability rests with your QA, validation and process functions.

A non-destructive measurement made on the installed, wetted filter to confirm the membrane and its seals are intact and that the assembly matches the condition the manufacturer's retention data was generated on. The common methods are bubble point, diffusion or forward flow, and pressure hold.

Its value comes from correlation: the manufacturer relates the physical test result to the bacterial challenge testing performed on that product, so a passing result on your installed filter indicates it is in the condition that data applies to. Because that correlation is product-specific, the test values and the wetting fluid must come from that product's documentation rather than from a general figure. An integrity test confirms the filter is intact — it does not by itself establish that your process is validated.

Datasheets, validation guides, integrity-test guidance, material 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 every brand, and their scope differs considerably between manufacturers and between product lines. State what your file actually needs at enquiry stage and availability can be confirmed for the specific item before an order is placed — which matters, because on regulated projects the documentation is frequently the longer lead time rather than the cartridge.

Sourcing enquiries are supported for reputed brands including Sartorius, Pall, Merck Millipore, Parker domnick hunter, 3M, 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. Where an equivalent is offered it is matched on membrane material, pore rating and its stated basis, dimensions, end-cap code and seal material — but note that on a regulated process, substituting a filter is a change to a validated process, so whether an equivalent is acceptable is your QA function's determination rather than a sourcing question.

The process fluid and the filtration objective first, then the pore size, required flow rate and allowable differential pressure, the cartridge length and the housing it must fit, the end-cap style and seal material, the process temperature and any sterilization requirement, and the integrity-test method if the process uses one.

After that: the pre-filtration arrangement, any brand preference or approved-vendor list your QA has qualified, and the quantity, delivery city, documentation requirement and timeline. If this is a replacement for a filter already in use, the existing part number and a photograph of both end caps settle the fit questions immediately.

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.

Membrane cartridges are supplied individually packaged and should be stored sealed, clean and within the temperature range the manufacturer states, since packaging integrity is part of what the filter's cleanliness depends on. Lead time is confirmed per line item at quotation stage — commonly stocked ratings and lengths move quickly, while specific brands, capsule formats and documented product lines are often imported to order.
