Wine

Beverages are one of the most controlled products of our daily life. Its quality becomes increasingly important for customers’ purchase decisions in the course of a conscious and sustainable consumption. Quality requirements often go far beyond faultless conditions of the product itself. The most important factors for customer retention are safety, trust and transparency when buying beverages. For the required quality assurance and raw material control knowledge about the composition of foodstuffs is essential.

Target Application: 

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.

Target User:

  • QC departments of producing industries in the area of beverages,
  • independent institutes and governmental control labs for food&beverages.
