Description
PALL AP-4910 Acrodisc One Syringe Filters with wwPTFE membrane - 0.2 µm (50/pkg 200/cs)Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build up and reduce system downtime. Sample filtration using syringe filters containing 0. 45 m (HPLC) or 0. 2 m (UHPLC) pore size membranes will also extend the life of chromatography columns
Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime. Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing. Pall’s Acrodisc One PSF Syringe Filters with wwPTFE membranes have been designed to protect analytical instrumentation and improve the reliability of results. wwPTFE membrane devices are chemically compatible with a wide variety of common solvents and are suitable for use in both aqueous and organic applications. These syringe filters are constructed with solvent compatible polypropylene material. The polypropylene plastic provides the syringe filter with exceptional strength, it is the highest grade of plastic with minimal additives and passes United States Pharmacopeia (USP) Biological Reactivity Test, In Vivo <88> plastics testing. Both the wwPTFE membrane and polypropylene housing are extremely low in levels of potential extractables that can lead to chromatographic interference. The devices are low in protein and API binding which make them ideal for drug studies, such as dissolution testing. Pall provides HPLC certification with these products, ensuring that analytical results will not be compromised by extractable filter materials. Pall membranes are tested for compatibility with common HPLC solvents including water, methanol, and acetonitrile, using established HPLC procedures. In addition, to verify low levels of UV-detectable extractables, samples of the syringe filters are evaluated prior to release. Acrodisc PSF Syringe Filters feature a large effective filtration area (3.9 cm2) for increased sample throughput, ideal for sample volumes of ≤ 150 mL. Pall Acrodisc PSF Syringe Filters are designed to be fully compatible for use with automated robotic handling systems offering reliable and worry-free operation.Shipping Notes

Good gift but particular gift for this difficult person to shop for
Format: Paperback
Got this as a gift for a friend and he was hard to shop for even after asking his wife. He's not a handyman, or a tech savvy man. He cooks, and is a well read man with interests in politics and psychology, he's not at all a gamer either. He doesnt DO much but work, it's not like he works out, golf's or anything like that... And they have a Brady bunch family and all she gave me to go on was he likes malcol x. And this author is more Malcom x than mlk and aggressive in views (when being compared to MLK) but is also very intertwined with their philosophies as he was IN it... According to the person I gave the gift to. Basically he loved it! So

Great Book.
Format: Mass Market Paperback
Its great to be able to go back and read Stokely Carmichael today in his own words. This book provides an excellent overview of what black power means and how the concept originated. Although the book seems a bit dated today, many of the ideas presented are still entirely relevant.
Ive only given the book four stars due to its age. Many of the statistics presented are dated, and undoubtedly there are other texts available today that present these ideas in a much better/newer way. But if you are interested in Stokely Carmichael and what he stood for, this is the book to read.
