Filtration Paper is mainly adapted to a filter funnel, to separate mixtures of insoluble solids into liquids.
Available in pack of 100 pieces in a box:
- Fast speed (Qualitative Filter Paper, Grade 101, ash content: 0.15%, Fast Speed) με 125mm diameter , suitable for large bean precipitates or colloids
- Medium speed (Qualitative Filter Paper, Grade 102, ash content: 0.15%, Medium Speed) with 240mm diameter or 150mm diameter , suitable for crystal sediments or small bean sediments
- Slow speed (Qualitative Filter Paper, Grade 103, ash content: 0.15%, Slow Speed) with 110mm diameter , suitable for separating fine crystalline precipitates from solutions.
