Description

PALL 4929 Acrodisc Syringe Filter with wwPTFE Membrane - 0.2 µm, 25 mm (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 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.

The Best Tote Bag EVER
Color: Khaki, Size: Small
It's perfect for work and everyday use! It's durable and lightweight. It's expandable at the bottom and the zippers work well. I bought it in size small in the light khaki color... Perfect for spring! It's very organized with pockets on the inside and a place for your iPad. I highly recommend it! I'm going to buy it as a gift for my daughters. It looks like the expensive bags, but at $25 it's a steal! I may get one in another color for the fall.

Best diaper/traveling bag!!
Color: Desert, Size: Large
Absolutely LOVE this bag!! The fabric of the bag was better than I even expected. It’s super soft, comfortable, easy to wipe down, has plenty of storage, sturdy even without stuffing it full, and is the perfect bag! It feels nice and thick without it being heavy. The zipper is also very durable and isn’t cheap feeling compared to other brands. I will definitely be ordering more in the future even to use for just traveling. I switched from a book bag diaper bag style to this bag and I feel like it holds even more! Plus, I love that you can expand this bag!! You won’t regret buying this one!!

My new travel bag!
Color: Chocolate, Size: Large
I love this bag. It will be my new travel bag, replacing my back pack. It has lots of pockets and looks fashionable. I love that it’s expandable. It will be helpful for those trips where I seems to bring back more than I originally packed. 🤭. The shoulder straps are long enough to give you adequate space to carry on your shoulder. I also live that it has a strap to put on that handle of your luggage. The size is perfect for fitting under the seat in front of you when flying. If it holds up during my next trip I will definitely return to purchase other colors. Great bag for the price!
