• Grade 403 and 313: Designed for applications in the pharmaceutical, chemical, wine, tincture, chromatography, and protein-free filtration processes in clinical laboratories.
• Grade 410 and 305: Specialized for filtration of difficult precipitates such as copper(I) oxide, lead sulfate, barium sulfate, manganese carbonate, and many others in analytical work. They are also suitable for extremely difficult filtration processes and for clarifying wine.
• Grade 413 and 303: Ideal for routine laboratory work, meeting the requirements of students in general chemistry, as well as for filtering aluminium phosphate, barium carbonate, lead chromate.
• Grade 415 and 301: For coarse precipitates such as aluminium hydroxide, cobalt carbonate, mercuric iodide, magnesium hydroxide.
• Grade 417: A creped paper (with a wrinkled surface) which allows rapid filtration when the retention of fine particles is not required.
• Grade 307: Particularly for the beer industry, a filter paper with an embossed surface of 70 g/m² for malt analysis according to EBC standards.
• Grade 600 and 310: Are general qualitative filter papers for general laboratories, universities and hospitals. In particular, they are made from 100% cellulose without binders.
• Grade 315: Suitable for gelatinous and coarse precipitates.
