Syringe filters with prefilters are GD/X, GD/XP and Anotop Plus. GD/X and Anotop Plus are used with glass microfiber prefilters that have high dirt loading capacity. Additionally, the prefilters used with GD/X have larger pores on the top surface (inlet side) compared to the pores on the bottom surface. This asymmetric pore structure further increases the dirt loading capacity of the prefilter. Prefilters used in GD/XP are constructed from polypropylene and are suitable for metal analysis applications.

We provide a range of syringe filters that contain built-in prefilters. These syringe filters are designed to make filtration easier for the user. Prefilters extend the useful life of the final membrane filter, enabling larger volumes to be filtered with reduced hand pressure.

  • GD/X Syringe Filters

    Our Whatman GD/X Syringe Filters are available in 13 and 25 mm diameter, sterile and non-sterile, with a range of membrane types and pore sizes.

    Whatman GD/X Syringe Filter range is specifically designed for high particulate-loaded samples. Constructed of a pigment-free polypropylene housing with a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media, these filters allow you to filter even the most difficult samples with less hand pressure. Whatman GD/X syringe filters can process three to seven times more sample volume than standard syringe filters.

  • GD/XP Syringe Filters

    Our GD/XP Syringe Filters are available with a range of membrane types.

    Whatman GD/XP Syringe Filters are suitable for use with samples that require inorganic ion analysis, as levels of ion extractables have been minimized. GD/XP syringe filters contain a two-layer prefilter stack comprised of 20 µm and 5 µm polypropylene filters. A range of membrane options are available for the last stage of filtration, positioned below the prefilter stack.

  • Anotop Plus Syringe Filters

    Anotop syringe filters can be used with most organic solvents and aqueous materials and are suitable for sample volumes up to 100 ml. The distinctive hexagonal housing is manufactured from pigment-free polypropylene to eliminate sample contamination. No wetting agents or adhesives are used in the manufacturing process.

    Anotop syringe filters contain the proprietary alumina-based Anopore membrane and are supplied in three pore sizes. Glass microfiber prefilter versions are available for difficult-to-filter samples.

    The Anotop Plus syringe filter unit is designed to enable difficult and hard-to-filter solutions to be filtered without adversely affecting the filtration efficiency of the final membrane. This can eliminate the need for sample clean-up or expensive and time-consuming sequential filtration.
