GVS Qualitative Filter Paper Grade 01 Medium; 10-13um Retention; 185mm Diameter

These filter papers are used for qualitative analysis. Qualitative filters are made of refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, which gives them a number of diverse filtration properties. The ash content of less than 0.06% is not reduced by post-treatment.

• Grade 01 medium filtration: the most widely used filter paper. Medium retention and flow rate. This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally this grade is used in qualitative analytical separations for routine laboratory work as well as rapid filtration of fine precipitates such as lead sulphate, calcium oxalate (hot) and calcium carbonate. In agriculture, it is used for soil analysis and seed testing procedures. In the food industry, Grade 01 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid.
• Applications: Filtration of a wide range of routine laboratory applications for medium retention; Filtration of fine precipitates such as lead sulphate, calcium oxalate, calcium carbonate and other metal sulphates; Soil analysis and seed testing; Food analysis; Education; Used in the beer and malt control quality production according to EBC.
