They are manufactured using inert cellulose with high alpha-cellulose content, with the addition of cotton linters.

Different levels of refinement of the raw materials and variations of the grammage make it possible to achieve different levels of retention. As such, we can offer filter papers to meet all manner of laboratory requirements.

Our filtering cards and technical laboratory papers are supplied in flat discs with or without holes, in square sheets with or without holes and in reams of 500 sheets. Our filtering cards and technical papers are packaged in packs of 100 sheets.
