Circles, quantitativ, wet strengthened, grade 1110
The wet-strengthened filter papers exhibit a very high degree of mechanical stability. They are resistant against acidic and alkaline solutions and are suitable for pressure and vacuum filtration. They are made of 100 % cotton linters. For maximum purity the papers are acid-washed and cleaned with demineralized water. Ash content is 0.007 %.
Grade 1110, medium fast filtering, particle retention 8-12 µm, filtration speed 20 s according to DIN 53137, basis weight 84 g/m², thickness 0.17 mm, wet strengthened
For relatively coarse-flaked precipitates (lead, iron, silver sulphides, alkali metal carbonate, lead chromate, arsenic, antimony, cadmium, foodstuffs). Especially high mechanical strength and resistance to acids and alkalis.
