Product Details & Documents
These smooth filter papers are made of refined pulp and linters with more than 95% alpha-cellulose content. The ash content of these filter papers is between 0,1 and 0,15%.
They are used for routine analyses like clarification, determination of substances, but also as discs with a centre hole for technical applications. Grades with a wet burst resistance >30 kPa are referred to as wet-strengthened and are therefore suitable for pressure or vacuum filtration.
Medium fast rate of filtration. Used for general laboratory filtration; essential oils; emulsions; essences; vinegar; extracts; yeasts; salt solutions; spirits; tinctures; water.
