Laboratory filter paper was one of the first products manufactured by the Cordenons Group at the beginning of the last century. Thanks to continuous research and product development, it remains a benchmark for qualitative laboratory filtration applications.

The common characteristic of the entire range is the use of high-quality refined cellulose, manufactured without chlorine, with low ash content and a neutral pH. Different degrees of pulp refining and variations in basis weight make it possible to produce filter papers with different retention capacities, meeting the requirements of a wide variety of laboratory applications.

Available Formats

Laboratory filter paper is available as:

• Flat filter discs with diameters of 12, 15, 18, 20, 25, 30, 40, 45, 50 and 60 cm
• Square filter sheets, supplied in packs of 100 sheets or reams of 500 sheets
