During the development of the analytical methods used in the labs of breweries, certain high quality grades of our filter papers have been established for analysis and strict QC in this area. In the newest edition of the instructions for "Analytical methods in breweries - Wort, Beer, Beer based Beverages", published by the Middle European Brewery Analysis Commission (MEBAK, 2013), high value Hahnemühle filter papers are recommended.
Target Application:
Sample preparation for the analysis of ingredients, contaminants and microbiological quality according to the § 64 Para.1 and 2 LFBG German law for food, feed and utensils.
The average ash content of our quantitative papers is 0,004%, and 0,002% ash of the hardened quantitative papers - the purest paper in the filter market.
