Description

“`

  • Type: Fast Speed Qualitative Filter Paper, specifically designed for effective retention of crystalline materials and suitable for a variety of general chemistry applications.
  • Diameter: 7cm, Bore Diameter: 20-25um, Filtration Rate: Less than 35 seconds, Ash Content: Less than or equal to 0.15%, Quantitate: 80 +/- 4 g/m2.
  • Loose paper with strong liquid absorbance, this filter paper is widely utilized in chemical laboratories for the filtration of sediments and suspended solids. Its ash content is higher than that of quantitative filter paper, resulting in a certain amount of ash remaining after combustion.
  • Non-Toxic and Tasteless: Free from additives, ensuring chemical stability. This filter paper is non-toxic and tasteless, with acid and alkali resistance, achieving filtration accuracy of up to 0.1 microns through hot-rolled processing.
  • Qualitative filter paper typically retains more ash, making it ideal for general qualitative analysis, precipitation, or suspension of solutions, though it is not suitable for quality analysis.

Specification:
