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