Description

PALL AP-4790 Acrodisc PSF Syringe Filters with PTFE Membrane - GxF/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.

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.

The GxF/PTFE 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.

Easy Read with good case studies!!
Format: Paperback
I had to purchase this for my Advanced Pathophysiology class in my Acute Care Nurse Practitioner program. It is very easy to understand and have pretty good case studies. I like that the CD that accompanies the book goes into some detail in explaining the cases further and the disease processes without giving you the answers to the questions. It stimulates one to think!! Once this class is over I will go back from time to time to review!!

Helpful
Format: Paperback
This is a nice compliment to other classroom instruction materials. I am teaching an advanced pathophysiology course in a nurse practitioner program. This book is very helpful for students to put together the concepts of patho with the clinical setting. Will use these for in-class group assignments. Case-studies are thorough and offer a variety of different disease processes to choose from. It certainly does not offer a case study for every possible disease or clinical scenario, but does cover most major areas and enough variety in my opinion. Should be helpful in reinforcing the clinical significance of some difficult to understand concepts. I would recommend this text to course instructors.

Good book!
Format: Paperback
Very helpful book for pathophysiology. The CD not only gives you answers to the case studies but gives you clear details of the clinical Pathophysiology of a particular disease. Definitely recommend it to students going for their Master's degree!
