The "universal" membrane filter for all of your analytical filtration requirements

• AutoPack™ packaging is easy to use and the Caliper** Automation Preferred™ certification assures you of smooth operation and worry-free performance 24 hours a day in automated workstations.
• Avoid the expense and inconvenience of keeping a variety of filters on hand. Versatile filter for aqueous and aggressive organic solvent-based solutions.
• Low protein binding membrane gives high recovery of critical proteinaceous samples.
• Accurate analysis. HPLC certified for low levels of UV-absorbing extractables.
• Easy filtration of particulate-laden samples with glass fiber prefilter version.
• 13 mm Acrodisc syringe filter with minispike configuration offers low hold up and easy filtration into autosampler vials.

**Caliper Life Sciences was previously Zymark Corporation

• Highly recommended for filtering HPLC samples and mobile phases.
• The Acrodisc PSF GxF syringe filter provides two to four times the throughput of standard prefilter devices for extremely viscous samples.
• Acrodisc PSF syringe filter is available in robotic-compatible AutoPack™ packaging for Caliper Prelude* , TPWII, and Multi-Dose* systems and Sotax* dissolution systems.

GH Polypro (GHP) Membrane is Extremely Low in Biomolecule Binding

¹²⁵I-labeled BSA (1.6 µg) or ³²P-labeled DNA (500 ng) were diluted to 5 mL in PBS (BSA) or Tris-EDTA (DNA) and filtered through a 13 mm disc of the indicated membrane. Filtration was carried out using a 10 mL syringe at a flow rate of 1.0 mL/min. Binding was determined by comparing the amount of radioactivity remaining in the membrane (triplicate) to the activity of the starting material by placing the disc or solution directly into scintillation cocktail and counting in a scintillation counter. Biodyne B membrane is designed for biomolecule binding and was used as a positive control.
