Description of No. 2 Filter Paper:

Hawach BIO 2 is equivalent to Whatman Grade 2 filter paper: No. 2 filter paper has a pore size of 8 μm, a medium flow rate, divided into round and sheet. Made of cotton linters and is a qualitative analysis filter paper.

Features of HAWACH No 2 filter paper:

  • Diameter: 50, 70, 90, 110, 125, 150, 180, 200, 220, 240, 250, 270, 300, 320, 350, 400, 450, 600mm.
  • ISO, CE dual certification
  • Production in the Class 100,000 cleanroom
  • Medium flow rate
  • HAWACH BIO 2 filter paper is equivalent to Whatman Grade 2
  • 8 micron filter paper has slightly stronger retention than No. 1 filter paper, but the filtration speed is relatively slow and the adsorption is stronger.
  • With a particle retention capacity of 8μm, in addition to the normal filtration of 8μm-sized particles, its additional adsorption properties also come in handy, for example,  8 micron filter paper to retain soil nutrients in plant growth experiments, and to monitor special pollutants in air and soil tests.

Application:

  1. No 2 filter paper is used in qualitative analysis techniques to identify the properties of substances.
  2. For example, the retention of soil nutrients in plant growth experiments.
  3. Detection of special pollutants in air and soil, etc.
  4. Standard analytical filter paper for the determination of meat, gelatin, feed, medicine, vitamins, tomatoes, infant milk powder, etc.
