Acrodisc® Syringe Filters with PTFE Membrane

Exceptional Chemical and
Temperature Compatibility

• 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.
• Ideal for filtration of gas and/or organic solvents.
• Prevents spurious peaks on chromatograms for accurate experimental results. HPLC certified for low levels of UV-absorbing extractables.
• Prevents "air bubble" lock when filling sample vials with 13 mm minispike outlet.
• 4 mm device offers the lowest sample hold-up (< 10 μL) and is useful for samples up to 2 mL in volume.

*Registered trademark

• Ultimate in chemical compatibility for filtering harsh chemicals that destroy other membrane materials.
• The Acrodisc PSF GxF syringe filter provides two to four times the throughput of standard prefilter devices.
• Moisture barrier for venting applications. 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.
