Highly pure filter paper (approx. 0.08% ash) recommended for qualitative analysis in laboratories.

  • Made of super- refined cotton linters and cellulose.
  • alpha-Cellulose content above 95%, therefore ensuring high stability and durability of the papers
  • Very low content of minerals (approx. 0.08% ash)
  • For precise identification of materials and for sample preparation prior to sensitive detection methods
