TCLP Glass Fiber Filters, Prewashed

These TCLP glass fiber filters use the same acid-treated glass microfiber media as our Standard TCLP Filters, but is then acid-washed using 1N HNO3, as described in EPA Method 1311.  The glass fiber filter media is thoroughly rinsed in a multi-stage process using copious amounts of high-purity deionized water.  Prewashing with acid further reduces the content of metals to exceptionally low levels.  This eliminates the need to acid-wash the filters in your lab, saving valuable time and reducing waste disposal and reagent cost. The glass fiber filter media contains no binders or other additives that may cause interference with samples.  The filters resist acids and bases, and have a nominal particle retention rating of 0.7um.
