Solid Phase Extraction Disks & Filters
CPI International offers a wide assortment of disks and filters for solid phase extraction (SPE), total suspended solids (TSS) and fixed volatile solids (FVS), and toxicity characteristic leaching procedure (TCLP).
Nu·Phase™ SPE Oil and Grease disks for EPA Method 1664A/B are high flow and high retention, which increases sample flow rate without compromising recoveries. Our Nu·Phase™ SPE disk line also offers disks for organic extraction methods using C-18, C-8, and SDVB phases.
CPI’s Weigh Better™ TSS and FVS filters are ideal to use for Standard Methods 2540C, 2540D, and 2540E. Pre-weighed, pre-washed, and un-prepared disks are available to meet the level of convenience you need and fit within your operating budget.
CPI’s TCLP filters are available as acid-washed, which is recommended for use in EPA Method 1311, or as un-prepared. Our TCLP filters are made of binder-free, borosilicate glass fiber and have a porosity of 0.7µm.
