Acrodisc® Syringe Filters with Nylon Membrane

Versatile Filter for Both Aqueous
and Solvent-Based Sample Filtration

• Acrodisc PSF syringe filters are Zymark* and SOTAX* Automation Certified to assure smooth operation and worry-free performance 24 hours a day in automated workstations.
• Excellent chemical compatibility with esters, bases, and alcohols.
• Saves time because no prewetting is required.
• Easy filtration of particulate-laden samples with the glass fiber prefilter version.
• 13 mm device with minispike configuration offers low hold-up and easy filtration into autosampler vials.
• Prevents spurious peaks on chromatograms for accurate experimental results. HPLC certified for low levels of UV-absorbing extractables.

*Registered trademark

• The Acrodisc PSF GxF syringe filter provides two to four times the throughput of standard prefilter devices.
• Not recommended for acids > 1 N or halogenated solvents.
• 25 mm Acrodisc PSF syringe filter is available in robotic-compatible AutoPack™ packaging for SOTAX AT-70 SMART* and CTS and Zymark TPW*, APW*, and MultiDoses dissolution systems.
