Description

PALL 4914 Acrodisc Syringe Filter with wwPTFE Membrane - 0.45 µm, 25 mm (200/pkg)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 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. Standard 25 mm Acrodisc syringe filters are designed for the filtration of sample volumes up to 100 mL. They feature an effective filtration area of 2.8 cm2.

Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!

Doesn't last long
Size: King (Pack of 1), Size: King (Pack of 1)
I have only had this pillow for 8 month and it is flat and not comfortable anymore. I sent the company an email and they never responded. I do now recommend that you buy this pillow.

The pillows have a chemical smell
Size: King (Pack of 1)
I bought two Marlow pillows a while ago. They are great pillows. The two new Marlow pillows I just purchased have a chemical odor. The manufacture date is Sept. 2024. I have them airing out hoping the smell will dissipate , so far that has not happened.
