Supplier: VWR International

Good for rapid filtrations where fine particle retention is not required.

Supplier: VWR International

Useful for very fine precipitates such as barium and lead sulfates, stannic and nickel sulfides, and calcium hydroxide.

Supplier: VWR International

Ideal for ultrapure filtration applications.

Supplier: VWR International

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

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

Used for drugs, pharmaceuticals, liquors, tinctures, chromatography, and protein-free filtrations in the clinical laboratory.

Supplier: VWR International

A collection to fit a wide range of critical applications.

Supplier: VWR International

Use for retention of zirconium hydroxide, aluminum hydroxide, cobalt sulfide, and other coarse or gelatinous precipitates.

Supplier: VWR International

Crepe fluted circles are ideal for gelatinous and coarse precipitates.

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.

Supplier: VWR International

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

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: VWR International

VWR® Vacuum Filtration Systems are designed for the preparation of buffers, tissue culture media, microbiological media, and other biological fluids.

Supplier: Cytiva

The Polypropylene/Polyethylene Separator Depth Filters have outstanding wet strength and can be folded or handled the same as laboratory paper. Because of their material of construction, these disc filters are virtually inert to chemical and biological agents.

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: Cytiva

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

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

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.

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

Recommended for microbiological culturing and sample preparation, these cellulose nitrate membrane filters offer very narrow pore size distribution and low levels of extractables.

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

Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including syringe filters, filter plates, centrifugal devices and membrane filter discs.
