Description

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.

Choo Choo Desk
Color: White, Size: 40inch without Power Outlet
When looking for a desk; you're considering size and practicality for your purchase. Additionally, you're hoping the assembly of the desk will not require a brain surgeon to apply assembly. As this is my second Choo Choo Desk purchase; both the price, size, practicality and assembly are top notch. My wife uses one as her craft/sewing platform and the other as her computer desk. In placing both side by side, she can negotiate from one to the other with little to no effort and as it offers enough room on each platform with drawers for her notions, notebooks and patterns; She is quite content with her Choo Choo Desk(s) set up. For those searching for a great desk, this Choo Choo set is ideal for minimum sized areas. One has a power bar with A/C and USB ports while the other is a simple desk corner to corner.

Good quality desk for the money
Color: White, Size: 40inch without Power Outlet
Overall this is nice little desk, cute, sturdy, and relatively easy to put together by myself. I took one star off because the bottoms of the desk drawers was missing. I contacted the seller and initially got a pretty quick response that the manufacturer would send replacement pieces and provide the shipping tracking information from the warehouse as soon as they had it. Then a few weeks went by without any word and I couldn't seem to contact anyone again (every link came up broken) so I thought I was essentially ghosted. But then they did contact me with the tracking information and eventually sent the replacement drawer flats. So it took almost two months to resolve but I did get the missing pieces and overall I'm pretty happy with this desk as it was exactly what I wanted for my small home office.
