PALL AP-4918 Acrodisc One Syringe Filters with wwPTFE membrane - 0.45 µm (1000/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 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

LOVE IT! But let's clarify the color!
Color: Apricot, Size: 14 Inch
Hi! I bought the 14" backpack in apricot. A few things stand out to me: 1) High Quality-this is a quality-made product. 2) The Apricot color is closer to a light tan or light sand color. 3) It was not as wrinkled upon arrival as I read elsewhere. I do not intend to steam the wrinkles out. I don't see that as necessary and I hate wrinkles.
It's beautiful! It's high-quality. It has every pocket and function you'd want. (see the videos.) Once I use it more, I'll add to my review if necessary. I love it. I'm happy a bought it and I think you would be too! Nice to get a product with such obvious quality!

Cute and company, but packing makes it VERY wrinkled
Color: Black, Size: 16 Inch
The bag is really cute and designed so well, can't believe how spacious it is yet compact! Not bulky and doesn't take up much room, lots of pockets. Perfect for both fashion and function. Took off stars thought because it came folded in half in its package and it's VERY wrinkled. Kind of takes away from it's look and makes it look bad :( pretty major wrinkles everywhere and I'm not sure if it can come out in this material, though I will try ironing it. If the company shipped it better it would be 5 stars.

Great stylish work backpack
Color: Black, Size: 16 Inch
I’ve had this backpack for a year and a half now and it has held up very well. I use it for work and work trips. It has many pockets for organization and fits everything I need including my 14 inch work laptop. Very stylish (not sporty) and appropriate for the office.
