Useful for a wide range of both aqueous and solvent-based applications. Hydrophilic nylon filters offer excellent chemical compatibility with esters, bases, and alcohols. Not recommended for acids >1N or halogenated solvents.

Supplier: Cytiva

These syringe filters offer a choice of filter media: hydrophobic PTFE membrane for exceptional chemical and temperature compatibility; hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without prewetting; GHP (hydrophilic polypropylene) membrane for low protein binding; and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and nonaggressive, solvent-based mobile phases. Polypropylene housing with female Luer-lock inlet and standard male slip Luer outlet connections. All membranes are HPLC certified for low levels of UV-absorbing extractables.

Supplier: Cytiva

These syringe filters are ideal for filtration of gas and organic solvents. They can also be used for air filtration and venting.

Cytiva's Whatman regenerated cellulose membrane filters are microporous cellulose acetate filters made without wetting agents. RC60 offers low extractables and wide compatibility in both organic and aqueous media.

Supplier: Cytiva

Filters are for removal of fine particulates and microorganisms and general clarification of HPLC, organic, and biological samples. Regenerated cellulose membrane is hydrophilic and low protein-building, with low extractables and resistance to a wide range of chemicals, making membrane ideal for HPLC work. Housing is solvent-resistant polypropylene with standard Luer-lock connections. Mini-Tip outlet is available for filtration into very small bottle samples. Filters are tested and certified for the absence of UV-absorbing substances at wavelengths of 214 and 254 nm with water, methanol, and acetonitrile.

Supplier: Cytiva

AcroPrep and AcroPrep Advance filter plates combine high performance membranes with unique well designs to provide fast processing with efficient removal of particulates. These plates are suitable for applications such as general sample prep, gross fractionation, call harvesting, and cell-based assays.

Supplier: Cytiva

A standard grade filter for boiler water analysis.

Supplier: Cytiva

Whatman mixed cellulose ester membranes are composed of cellulose acetate and cellulose nitrate. These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters.

Grade #415.

Supplier: Cytiva

For filtration of aqueous and some organic-based samples. Two prefilters [gradient density multigrade GMF 150 (10:1µm) and Grade GF/F (0.7µm)] allow filtration of even the most difficult samples with minimal hand force. Choose the 13mm size for samples up to 10mL or the 25mm size for samples greater than 10mL.

Supplier: Cytiva

Easy to use, versatile, disposable filter funnels are ideal for microbial analysis. Polypropylene construction eliminates compatibility or extractables issues. Ergonomically designed units allow for removal of funnel cylinder with a squeeze. The base and cover convert to a petri dish for culturing the membrane in place, or the membrane can be cultured on a separate petri dish. Unit fits directly onto a standard manifold, or a stopper/adapter combination can be used for other manifold styles. Gamma irradiated. Bulk packed. Volume: 100mL.

Supplier: Cytiva

A filter for every step in your process. From drug discovery and basic research to process development and production, Pall Laboratory’s AcroPak capsules come in a variety of membrane types and volume sizes.

Supplier: Cytiva

For vacuum filtration of liquids, especially for the analysis of aqueous samples for microbiological and particulate contamination using the Membrane Filter (MF) Technique.

Supplier: Cytiva

These premium syringe filters combine the benefits of a multi-layered prefiltration device with an automation-certified filter housing. The polypropylene housing has been designed to withstand high operating pressures. Some models feature a GxF borosilicate glass prefilter, which provides two to four times the throughput of standard glass fiber prefilter devices, allowing for quick and easy filtration of difficult-to-filter samples.

Supplier: Cytiva

This disposable protective device is designed to prevent aqueous liquid and aerosol contamination of vacuum pumps or aspiration suction systems.

Supplier: Cytiva

Whatman Grade 4 Qualitative Filter Papers are a standard grade, high flow rate filter paper. They are useful in qualitative analytical separations when fast flow is required and the collection of fine particles is not critical.

Supplier: Cytiva

Whatman™ Uniflo™ syringe filters are well suited for rapid, routine syringe filtration of small volume samples up to 100 ml in laboratory sample preparation.

Supplier: Cytiva

Whatman Grade 1 Qualitative Filter Papers are the most widely used filter paper for routine laboratory applications, qualitative analytical separations, and clarifying liquids. They are the standard grade cellulose filter papers for medium flow rates.

Supplier: Cytiva

Membranes are made from pure cellulose acetate, making them ideal for biological and clinical analysis, sterility tests, and scintillation measurements. Filters exhibit very low protein binding capacity and are hydrophilic, making them suitable for aqueous and alcoholic media. The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols, and increased heat resistance. The membrane filters exhibit high physical strength and can be used up to 180°C (356°F), making them suitable for hot gases and allowing them to be sterilized by all methods without sacrificing the integrity of the membrane.

Supplier: Cytiva

Puradisc™ syringe filters combine premium quality and economy. They are ideal for the quick, efficient filtration of samples up to 100 mL volume. Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated). Options include a sterile, medical-grade blister pack for critical applications and a special tube tip outlet that allows the sample to be accurately dispensed into a micro-vial, eliminating air lock.

Supplier: Cytiva

Ideal for filtration of gas and organic solvents. Also used for air filtration and venting.
