过滤器 滤纸 Qualitative Filter Paper
These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Slightly more retentive and more absorbent than grade 1. In addition to general filtration in the 8 μm particle size range, the extra absorbency is utilised, for example, to hold soil nutrient in plant growth trials.

  • Folded filters expose extra surface area, which enables a higher loading capacity and shorter filtration time
  • Folded filters are suitable for extracting samples from soil to support contaminant testing in the presence of weakly acidic solutions
