PALL AP-4914 Acrodisc One Syringe Filters with wwPTFE membrane - GxF/0.2 µm AutoPack tubes (25/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. The GxF/wwPTFE membrane configuration features a a GxF multi-layer glass fiber prefilter, providing two to four times the throughput of standard prefilter devices. The multi-layer prefilter captures particulate rated from > 40 to 1 μm.Shipping Notes

Love it.
Color: Bunny (Beige), Size: Large
Good quality and well worth the price. My dog loves it. The squeaky part is fun, and the crinkly, tear-resistant paper in the ears makes playtime even more exciting.

Great for my aggressive chewers
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
Wears my Labs out. Fred the yellow lab chooses this pig ear over all his nyla and natural chews out of the toy box all the time. This is the 4th one in his 6 years. They have lasted long and when new are large enough I don’t have to worry about choking. As they get down in size I throw them just as a precaution. The only con I can think of is Fred loves to slam it down on the pergola floor which makes for a very loud clacky sound and it scares the $%^ out of me. He of course thinks it’s funny so he picks it up and continues to do it. As long as he and his brother Willie can chew I will always have these in their toy box.

Great chew toy for large, tough chewers
Size: 1 Count (Pack of 1)
My dog is a heavy, strong chewer over 100 lbs who will chew this for an hour. It lasts, keeps him occupied and the smell isn’t terrible. Love the large size for a larger dog. Great buy.

Awesome bone for all dogs!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
My dogs LOVE this pig ear! It is very lightweight and easy for any dog, from my Great Dane to my Maltipoo, to carry and chew on. It has no odor, yet the dogs were interested immediately after smelling it. The pig ear is perfect for every dog in our household and keeps them busy for hours. Since it is curved, it is easy for them to hold on to and to pick up. We have had this bone for a few weeks, and it has lasted through our little dogs, fosters, and Great Dane! The bone is very durable, and based on the previous bones we’ve gotten from Pet Qwerks, I’m guessing it’s going to last quite a while! I recommend this to anyone wanting a long-lasting bone for their pups, especially those tough chewers!
