Description of filtration filter paper BIO-2

Hawach BIO-2 qualitative filtration filter paper is Whatman Grade 2 equivalent quality with competitive price in the market, which has a moderate retention rate and flow rate (8μm). Laboratory filter manufactured to ISO 9001 environmental management standards and all passed the CE certificates.

Compared with filter paper disc 1, filtration filter paper bio 2 has a slightly higher retention rate and load capacity, and the filtration time increases accordingly (such as slower filtration speed). In addition to the ability to retain small particles of about 8μm, the strong adsorption capacity also has its advantages. For example, laboratory filter can be used as plant growth test paper, and the paper can retain nutrients in the soil to continuously provide nutrients for plant growth. Filter paper roll is also used in air and soil tests to monitor specific pollutants.

In addition to the commonly used disc filter paper, Hawach also produces filter paper roll. Same as qualitative filter paper chemistry grade BIO-113,
filter paper grade 2 covers a wide range of laboratory applications and is frequently used for clarifying liquids. Hawach also provides pre-folded qualitative filter paper. Compared with ordinary filter paper, folding can increase the flow rate and load of the filter paper.
