Acid WashedLow Metal TCLP Filters

The TCLP filters are made with acid-treated borosilicate glass microfibers with inherently low levels of barium and zinc, and then acid-washed using 1N HNO₃, as described in EPA Method 1311. The 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.
