Ion Chromatography (APHA 4110)

Whatman™ GD/X Nylon Syringe Filters Available on GSA/VA Contract for Federal Government customers only.

Designed to enable the filtration of viscous, hard-to-filter samples greater than 10mL. Whatman™ GD/X Nylon Syringe Filters are hydrophilic and a good choice for aqueous and aqueous organic samples. Nylon (NYL) membrane offers good chemical resistance to most common HPLC solvents.

Whatman™ GD/X PTFE Syringe Filters Available on GSA/VA Contract for Federal Government customers only.

Designed to enable the filtration of viscous, hard-to-filter samples greater than 10mL. Whatman™ GD/X PTFE Syringe Filters are hydrophobic and will not allow water to pass without high pressures. Aqueous solutions may be filtered if the membrane is initially “wetted” with alcohol or another appropriate solvent. PTFE membranes will stop aqueous aerosols in gas streams.

Whatman™ GD/X Disposable PVDF Syringe Filters Available on GSA/VA Contract for Federal Government customers only.

Processes three to seven times more sample volume than filters without prefilter. Whatman™ GD/X Disposable PVDF Syringe Filters are specifically designed for filtration of viscous or otherwise hard-to-filter samples with high solids content.

Whatman™ GD/X Disposable Syringe Filters - Cellulose Acetate (CA) Available on GSA/VA Contract for Federal Government customers only.

Provides solutions to high-loading capacity and low protein binding concerns. Whatman™ GD/X Disposable Syringe Filters - Cellulose Acetate (CA) reduces the number of prefiltration steps necessary for difficult-to-filter samples

Whatman™ Mini-UniPrep™ Syringeless Filters Available on GSA/VA Contract for Federal Government customers only.

Processes sample loads in one-third the time. Whatman™ Mini-UniPrep™ Syringeless Filters provide a faster and easier way to remove particulates from samples being prepared for HPLC and UHPLC analysis.

Whatman™ GD/X Polypropylene Syringe Filters Available on GSA/VA Contract for Federal Government customers only.

Designed to enable the filtration of viscous, hard-to-filter samples greater than 10mL. Whatman™ GD/X Polypropylene Syringe Filters provide a pure, single-material-construction filter device with a broad range of solvent/chemical resistance.

Whatman™ GD/X Disposable PES Syringe Filters Available on GSA/VA Contract for Federal Government customers only.

Minimizes adsorptive protein loss when filtering protein-containing solutions. Whatman™ GD/X Disposable PES Syringe Filters are suitable for preparing viscous, dense, or otherwise difficult-to-filter samples prior to a variety of analytical methods.

Whatman™ Mini-UniPrep™ Amber Syringeless Filters Available on GSA/VA Contract for Federal Government customers only.

Produced with the same colorant used in pharmaceutical containers

Whatman™ Mini-UniPrep™ Syringeless Filters with Preslit Septa

Processes sample loads in one-third the time. Whatman™ Mini-UniPrep™ Syringeless Filters with Preslit Septa provide a faster and easier way to remove particulates from samples being prepared for HPLC and UHPLC analysis.
