Filter Design

Pall Life Sciences' broad range of device sizes assures complete sample filtration with minimal sample loss. In addition, many Acrodisc Syringe Filters offer the option of a minispike outlet, rather than the traditional male luer outlet. The minispike outlet, available on 13 mm PTFE, Nylon, GH Polypro, and PVDF Acrodisc Syringe Filters, allows for easy dispensing into autosampler vials.

wwPTFE (Water Wettable Polytetrafluoroethylene)

The wwPTFE membrane is ideal for sample preparation and solvent filtration.

• Extend column life up to 52x
• Improve result quality with up to 24% less filter extractables and lower adsorption
• Use one membrane filter type for all your sample preparation applications
• Hydrophilic wwPTFE membrane also available in two LCMS-certified configurations

MS wwPTFE (Water Wettable Polytetrafluoroethylene)

LC-MS certified filter with extremely low levels of extractables

• Hydrophilic polypropylene membrane offers excellent chemical compatibility.
• Suitable for aqueous and organic solvents.

LC-MS certified 

• Minimize interference in your LC-MS results with the MS wwPTFE syringe filter. The first LCMS certified filter with extremely low levels of extractables.

Low ion suppression/enhancement

• Reduce the need for retesting.
• MS wwPTFE syringe filters will not contribute extractables that will interfere with the ionization process, which is the heart of the
  LC-MS technique.

Protective packaging design

• Save money and prevent downtime due to accidental contamination. Filters are packaged into separate tubes to protect them from external sources of extractables. While one tube is in use, the others are kept sealed.

Excellent chemical resistance

• Use this universal filter for all your LC-MS samples. The WWPTFE (water wettable polytetrafluoroethylene) membrane can be used with both organic and aqueous solvents.
• When coupled with a polyethylene housing, the membrane offers excellent chemical resistance.

Low protein binding

• Get accurate and confident quantitative results. There is minimal protein adsorption with the MS wwPTFE syringe filters.

Particulate retention

• Using Acrodisc MS syringe filters will protect your columns and instrument from particulate buildup, making your columns last longer and your LC-MS perform more consistently.
