SMOOTH SURFACE QUALITIES
QUALITY 102-F: Very slow filtration, equivalent to Whatman 2v, this has a high particle retention rate. Regularly used in agriculture laboratory soil analysis. Can also be used for air contamination controls. Particle retention in excess of 2 µm.
QUALITY 113-F: Medium – rapid filtration, used for current analysis in laboratories. Particle retention in excess of 6 µm.
QUALITY 180-F: Rapid filtration. This is the most common type of filtration used for qualitative analysis in laboratories. Particle retention in excess of 10 µm.
QUALITY 600-F: Extra rapid filtration, which makes this especially recommended for filtration of tinned viscose liquids (syrups, oils, essences etc). High grammage paper recommended for retention of gelatinous precipitates. Particle retention in excess of 50 µm.
ROUGH SURFACE QUALITIES
QUALITY 70-FC: Rapid filtration, equivalent to Whatman 114v. Low grammage paper for economic filtrations. Used in the filtration of viscous products with a high content of suspended particles. Particle retention in excess of 25 µm.
QUALITY 90-FC: Very rapid filtration. With a higher filtration specific surface than smooth textured papers. Used in the sugar industry during the harvest brix grade determination process.
QUALITY 117-FC: Very rapid filtration, equivalent to Whatman 113v, this has a high particle retention rate. Generally used in the filtration of essences, resins, oils etc. Retention of a high quantity of flocculants and precipitates. Particle retention in excess of 40 µm.
