Description

PALL AP-4501 Acrodisc PSF Syringe Filters with PTFE 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.

PTFE membrane is highly chemically compatible for the filtration of harsh solvents that can destroy other membrane materials. PTFE is a hydrophobic membrane, so it will repel water and is not suitable for the filtration of aqueous solutions.

As well as being suitable for the filtration of organic solvents in applications such as HPLC and UHPLC sample preparation, the hydrophobic nature of the PTFE membrane makes these syringe filters ideal to use in gas filtration or as a moisture barrier in venting applications.

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.

Pug At The Beach loves Jack Canfield
Format: Paperback
Far too many people wander through life unfulfilled because they lack the skill set needed to experience life to its most bountiful. That's in part due to a fear of asking for that which brings us what we need, want or desire. People are afraid. Afraid of rejection, afraid of looking foolish, and a whole host of other things. Be afraid no longer. The Aladdin Factor will teach you how to ask without fear. Canfield's book taught me how to ask in a powerful, confident way that would guarantee my success. Simple phrasing combined with subtle reflection made for a life transforming read. At Pug Headquarters, it's a must read. Diana Taylor Top Dog Pug At The Beach Sometimes all you need in life is the wisdom of a good dog.TM

Good not great
Format: Paperback
Good advice on asking, could be a bit more content on how to actually ask. Most examples seemed to be more made up than practical. Still good book.

Ask and Ye Shall Receive...
Format: Paperback
The writing and the approach in the book are not earth shattering. In fact, I wish there was a little more meat or pizzaz in the content. So, why the recommendation? Simple - the content at its core is incredibly powerful - and we all need the reminder. Our gentieel approach to communications and emotional interaction has left us forgetting to ASK for things. We expect the world to be mind readers, and get upset, frustrated or depressed when we don't get what we want. Of course, since we never actually ASKED for what we wanted, we rely on guesswork and luck to achieve our dreams and goals. The genie in the lamp could grant wishes, but those wishes needed to be spoken by Aladdin. Similarly, we are all in a position to achieve our goals and dreams, but they must be spoken. Even within ourselves, we cannot harness our own power of desire and subconscious until we solidify the desire by asking for it. An absolute must read - even if the writing style is a bit flat - the content is NOT.

Great book, however...
Format: Paperback
There are many great things about this book and very useful advice and information, however it is very repetitive and some of the excerpts are a bit long and boring. I still recommend it, just be warned.
