PALL AP-4916 Acrodisc One Syringe Filters with wwPTFE membrane - 0.45 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

Hydrated and protected
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
I loved this spf, as someone who’s had skin cancer multiple times now, protecting my skin is 100% a nonnegotiable (darn 80s and baby oil) this keeps me hydrated and protected at the same time! Easy, light cream like application without a weird white cast.

Good coverage
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Great sunscreen and when applied liberally my face doesn't get burnt. That has always been a problem with my skin all my life so I'm happy for that sort of coverage.
The formula is a little greasy and there is a white caste but I use it to my advantage as it dims the red spots on my face and brightens my under eye. I try not to leave the house without applying.

Smooth sunscreen

Great for mature skin. Not easy finding something for mature skin that doesn’t cake or flake off. Moisturizing. I will buy again !
