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.

Game Changing Information!
I bought this book months ago and like many others, it found its way to a pile of books I like to call "I'll read them eventually". Yesterday was eventually. A simple read, finished it in one sitting and came away with mountains of info that will save me thousands and even get me money back on previous years taxes. Great info on tax investing strategies as well, well worth the purchase price, and I can't wait to write it off!!

Great advice & tips
Format: Kindle
This book is helpful to new business owners with little to no experience with business tax preparation. I had about 5 pages that was helpful to me because I have had my small business for 8 years and familiar with some of the home based business write offs but there was some useful information that. Are it worth the read.

Easy read, but very repetitive in the beginning
Format: Paperback
It’s an easy read, however it’s very repetitive. I’m about halfway through the book and it still doesn’t really tell me anything. I need to know it’s just talking about. It’s important to keep good record keeping and we will talk about it in the later chapters like I’m already on chapter 13 on page 60 and I’m still waiting to learn more stuff because it’s just repetitive. I’m hoping that changes but it’s a little bit frustrating.
