• Wet-strengthened, ashless filter paper, which is slightly more retentive than MN 1640 m with corresponding increase in filtration time

• The smooth surface allows fiber-free filtration, even for highly acidic and basic media

• Surf

• Allows the quick and easy detection of hydrocyanic acid and cyanides in aqueous solutions and extracts, which are, for example, formed in the manufacture of fruit brandies and are toxic even in low concentrations

• To detect cyanides in sol
