Pall unveils Acrodisc syringe filters with water-wettable PTFE membranes

Pall Corporation, a global leader in filtration, separation and purification, has introduced Acrodisc^® syringe filters with universal water-wettable polytetrafluoroethylene (wwPTFE) membranes for analytical instrument applications. The new syringe filter helps protect HPLC/UHPLC columns and instrumentation from particulate buildup, plus helps ensure accurate data.

The Pall Laboratory wwPTFE membranes can:

• Extend column life up to 52 times
• Reduce contamination with up to 24% less filter extractables than competitive products
• Simplify sample preparation, saving time and money

The versatile Acrodisc syringe filter with wwPTFE membrane is ideal for aqueous samples and solutions containing aggressive organic solvents. Accurate analysis is ensured with HPLC certification for low levels of UV-absorbing extractables. In addition, Acrodisc syringe filters with wwPTFE membranes’ universal use helps avoid the expense and inconvenience of keeping a variety of filtration products in inventory.

Acrodisc syringe filters with wwPTFE are available in 13 mm and 25 mm. The 13 mm Acrodisc syringe filter is available with a minispike outlet that offers low hold-up volume and easy filtration into autosampler vials. This feature filters four times as much sample with the same hold-up loss as a typical 4 mm filter. An optional asymmetric glass-fiber prefilter also is available that provides higher particulate-holding capacity for greater throughput and volume. The Acrodisc ONE PSF syringe filter with wwPTFE membrane is automation-certified to ensure smooth operation and worry-free performance.

Additionally, the wwPTFE membrane is also available in Nanosep^® spin devices for low volumes and AcroPrep™ Advance filter plates for processing up to 96 samples at once.
