Pall's Superior Media Separation Technology Ensures:

• Accurate pore size ratings for better chromatography and instrument and column protection.
• Uniform membrane materials (lot-to-lot) for consistent analytical results.
• Low extractable materials for less chromatographic interference.
• Materials of construction selected specifically for analytical analysis with lower extractables and lower API (Active Pharmaceutical Ingredients) adsorption.

Exceptionally Low Extractable Levels

The specific quality of raw materials, amount of quality control, membrane extraction procedures, and post-treatments all affect the resultant membrane properties and amount of extractable materials. Pall specifically selects the highest grade of materials and performs rigorous extraction methods on our membrane products to hinder the occurrence of undesired artifacts. Choosing membranes that are compatible with your fluids and experimental conditions will reduce/eliminate extractables. More about extractables...

Certified Syringe Filters

Pall certifies Ion Chromatography (IC) Acrodisc PSF syringe filters have been tested using a highly sensitive IC protocol to monitor inorganic extractables. Actual background levels of filter extractables are typically less than 20 ppb for chloride, 6 ppb for nitrate, 1 ppb for phosphate, and 10 ppb for sulfate.
