bacteria cultures and for radioimmunoassay with weak beta emitters

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

Grade 121 is also used in membrane pre-filtration and is also found in quantification of solids
