PALL AP-4910 Acrodisc One Syringe Filters with wwPTFE membrane - 0.2 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

Picture is misleading
Color: RYLCC-BLK
Great product! Good quality! The picture of the product is a little misleading as it looks like there are 2 tubes instead of one.

Perfect sized wrist-rest!
Size: Compact, Size: Compact
Great wrist-rest! Very squishy and feels comfortable & cool even after hours at the computer. The rubber gripper bottom is effective & it never shifts around for me. Also, love that it fits the length of my 75% keyboard & my boyfriends 60% Wooting 60HE keyboard perfectly

Very Pleased!

Review for: Cooling Gel Wrist Rest Pad -Full Size 18"- Memory Foam Palm Rest with Non-Slip Footpad - Ergonomic Design Wrist Support - Desk Keyboard Accessory Gaming Gear (Large-Full Size). I've had this for a week and I'm impressed! There is no skimping on quality, which is rare nowadays. It is made extremely well, solid yet soft. I love the feel of the outer cover. It's comfortable and stays in place. And let me add... I'm putting it to the test. I have a rolling over-bed/couch desk. It has a raised 1/4" lip around the top. I put this wrist-rest on top of that lip. So far there's not any wear across the bottom of this wrist-rest. And that's with me using it for my wrists... and my elbows. It far surpasses the last rest I bought. From my experience, many sellers slap the phrase "memory foam" on their products when they are not. That's NOT the case here. This rest immediately bounces back to its original shape. It's true memory foam! It's so comfortable that I forget it's there yet I enjoy the comfort immensely. Also, it has no smell. ***From my experience so far... I highly recommend this product!

Comfortable and functional, but beware of cardboard/mdf insert
Size: Compact
I’ve been using this wrist rest for a bit now, and for the most part, it does exactly what it’s supposed to do. It provides a comfortable amount of support for my wrists during long typing sessions, and the cooling gel aspect is definitely a nice touch that adds to the overall comfort.
That said, there are a couple of drawbacks to keep in mind. The surface seems to attract dirt and grime pretty quickly, so you’ll need to wipe it down often to keep it looking clean. More importantly, the build quality of the base is disappointing. I believe its a cardboard inserted into the bottom, which snapped very easily when I was just barely bending it while cleaning it. It’s a shame because the rest of the product is great, but I really wish they had used a more rigid, durable material for the bottom instead of whatever this cardboard/mdf is. This is why I’m giving it 4 stars.
