Supplier: VWR International

Binder-free VWR® glass fiber filters feature fast flow rates, high-loading capacity, wide thermal tolerance, and excellent precipitate retention.

Supplier: Avantor

Placed immediately before the column, the precolumn filter traps particles introduced with the sample. For samples, which may irreversibly absorb onto the column, the use of guard cartridges is strongly recommended.

Supplier: VWR International

Use to: Concentrate, purify, and desalt peptides, proteins, oligonucleotides, DNA, and RNA; clean up labeling and PCR reactions; isolate DNA from agarose gel slices; buffer exchange; separate proteins, oligonucleotides, and RNA from acrylamide gels; clarify samples; or remove particulates.

Grade #415.

Supplier: VWR International

Uses include filtration of aluminum phosphate, zinc ammonium phosphate, and silver chromate.

Supplier: VWR International

Systems for vacuum filtration of aqueous solutions including cell culture media, buffers, or other biological fluids.

Supplier: Cytiva

Reusable, in-line filters with 50 mm hydrophobic PTFE membranes in polypropylene housing.

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

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: PALL LIFE SCIENCES MX

Ideal for biological, pharmaceutical, and sterilizing filtration requirements. Supor® hydrophilic polyethersulfone membranes offer higher fluid flow rates, lower protein binding, lower extractables, and greater strength than other cellulosic (acetate, nitrate) membranes. Provide some of the highest water flow rates and fluid filtration capacities of any sterilizing grade membrane filter. Nonsterile, except for 28147-979, which is gamma-irradiated.

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

Acrodisc™ syringe filters with Supor™ membrane deliver high flow rates and low protein binding.

Supplier: VWR International

This 2.5 L system allows for the safe and effective collection of waste in the laboratory. The safety and ease of use for laboratory technicians is a high priority. The closed-loop design prevents inhalation of volatile organic componds.

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

This depth-type filter medium is useful for prolonging membrane filter life in liquid systems that contain substantial amounts of particulate matter.

Supplier: Cytiva

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

Supplier: Cytiva

For prefiltering heavily contaminated aqueous or solvent based samples. Filters are made of 100% binder-free borosilicate glass fiber. Hydrophilic nylon membrane has excellent chemical compatibility with esters, bases, and alcohols and does not require prewetting. GHP (hydrophilic polypropylene) membrane is low protein binding. Both nylon and GHP membrane filters include a glass fiber prefilter layer, as well as being HPLC certified for low UV-absorbing extractables. The regular glass fiber membrane has very low extractables. Polypropylene housing. Female Luer-lock inlet and male slip Luer outlet.

Supplier: Cytiva

Ideal for the isolation and enumeration of yeast and mold colonies from water and beverages using the Membrane Filter Technique referenced in Standard Methods for the Examination of Water and Wastewater. Dark background provides an excellent contrast for counting opaque colonies and light colored particulate.

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.
