High performance:

For both simple and demanding analytical requirements; these syringe filters offer premium quality and efficiency

Contains proprietary alumina-based membrane, extremely small pore size.

Anotope filters can be used for most organic solvents and aqueous materials.

High performance filters with the most options for membranes, diameters and applications.

Designed for pre-filtration of difficult-to-filter aqueous or organic solutions containing particulates

CA, CN, RC, PTFE, H-PTFE, Nylon, PP, DpPP, PES, PVDF, GMF

Difficult Filtration:

For use with high-particulate and viscous samples; these syringe filters contain two or more filter layers for efficient and cost-effective filtration without blockage

With a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media.

GD/X syringe prefilters can handle three to seven times more sample volume than standard syringe filters.

Contains a proprietary polypropylene pre-filtration stack suitable for inorganic ion analysis.

GD/XP syringe prefilters contain a two-layer prefilter stack consisting of 20 μm and 5 μm polypropylene filters. The last
stage of filtration is by membrane, which is positioned below the prefilter stack.

Automated Systems:

These robust syringe filters are compatible with most high throughput and/or dissolution systems.

For difficult-to-filter samples, Whatman Roby syringe filters are also available with an integrated glass fiber prefilter.

The filter housing is made of mechanically stable polypropylene.

Application Specific:

For specific applications: HPLC, IC and LC with certification; bioethanol and protein purification production; environmental sampling prior to COD/DOC analysis

For easy and effective preparation of samples prior to HPLC. These syringe filters preserve the life of your column by efficiently removing particles from your analytical samples. Because the Anotop LC Syringe Filter is made of pigment-free polypropylene and the inorganic Anopore membrane, you can be sure that after filtration the level of extractable UV-absorbing compounds is minimal.

For reproducible results in the filtration of organic or aqueous solutions in HPLC.

For batch-to-batch consistency, the Whatman SPARTAN range of filters is tested and certified for the absence
of UV-absorbing substances at wavelengths of 210 and 254 nm with water, methanol, and acetonitrile.

Whatman's syringe-less all-in-one filters and filter vials are pre-assembled, convenient filtration devices for removing particles from samples. They replace syringe-coupled filtration devices with a single, disposable unit, making sample preparation easier, faster and more efficient.
