Phenomenex Catalog International 2009 - (Page 8) Filtration Centrifugal Filters FILTRATION Filtration Products Filtration Products from Phenomenex "Filtration is the easiest way to improve your results, guard your system components from damage, and protect your column investment". Regular sample filtration means: • Less system downtime • Fewer troubleshooting problems Removal of particulate matter to sub-micron levels is critical before any drug, tox, or dirty environmental sample is injected into an HPLC, GC or mass spectrometer. Also, products that remove matrix components, interferents, and chemical garbage will improve your results. Check out the following: Spinex ™ Disposable Centrifugal Filter • Convenient filtration of multiple HPLC and GC samples • High recovery for small samples • Nylon, PTFE (Teflon®) and Cellulose Acetate membrane materials IN-LINE FILTERS | Mini-Index Page No. Spinex disposable centrifugal filter units provide a convenient means of filtering multiple HPLC and GC samples without the necessity of manually forcing each sample through the filter with a syringe. ™ Filtration Products (General Laboratory) • Syringe filters 4-5 • Membrane filters and filtration apparatus 6 • Centrifugal filters 8 Solid Phase Extraction (SPE) devices • Tubes and well plates 9-35 • Vacuum manifolds 32-33 Column Protection devices • SecurityGuard • Analytical (2 to 8 mm ID) 249 • SemiPrep (9 to 16 mm ID) 251 • PREP (18 to 29 mm ID) 251 • PREP (30 to 49 mm ID) 251 • Inlet filters • Biocompatible PEEK 7 • Stainless steel 7 • In-line filters • Biocompatible PEEK Analytical 346 • Stainless steel Analytical 346 Prep 346 Quality filtration and sample preparation products from Phenomenex offer a convenient, inexpensive way to clarify all your samples – for peace of mind and improved analytical results. All you need is a laboratory centrifuge with sufficient capacity for the number of samples to be filtered at one time. Centrifugal force drives the sample through the filter quickly without effort on the part of the chemist. No cleaning of syringes is required between samples. Samples contact only the Spinex filter unit itself and the polypropylene receiver tube. After filtration the upper portion of the tube containing the membrane filter can be discarded. The receiver tube serves as a container for the filtered sample and can be retained as long as desired. Separate caps are supplied for the sample chamber and the receiver tube. Filter membrane materials available are Nylon 66, PTFE (Teflon®) and Cellulose Acetate (CA). Nylon 66 Spinex filter units are recommended for most HPLC and GC sample filtration work. They are chemically resistant, compatible with all commonly used solvents, and virtually free of extractable materials that could contaminate samples. PTFE (Teflon®) Spinex filters are designed to handle more aggressive organic solvents, whereas Cellulose Acetate (CA) is especially well-suited for the filtration of proteinaceous samples in aqueous solvents.
