Quantitative Glass Microfiber Filter Paper - 0260-0470 - Grade 26, 4.7cm
$166.50
Ahlstrom-Munksjö 26
This grade uses the same acid-treated glass microfiber media as Grade 193, which is then acid-washed using IN 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 costs.
