Hawach Qualitative Filter Paper BIO-1 Introduction
Hawach BIO-1 filter paper has a particle retention of 11 μm. BIO-1 filter paper is the most frequently used in daily filtration. It is a chemical analysis filter paper with medium retention capacity and flow rate. The diameters are 55mm, 70mm, 90mm, 110mm, 125mm, 150mm, 180mm, 185mm, 240mm, 270mm. This level covers most laboratory applications and is often used for liquid clarification. Also isolated by traditional qualitative analysis of precipitates, such as lead sulfate, calcium oxalate (hot) and calcium carbonate, which are cellulase activity, drilling fluid reactive clay, protective cloth resistance, penicillin, solid waste, chlorine weeding standard filter paper for the determination of the agent.
1. In agriculture, it is used for soil analysis and seed testing.
2. In the food industry, BIO-1 filter paper is often used to separate solid foods or extract liquids from related liquids and is also widely used for simple qualitative analysis and separation in teaching.
3. In the aspect of air pollutant monitoring, there are discs and coils available for use, collecting atmospheric dust from the atmosphere and then measuring the degree of pollution with a photometer.
4. In the gas detection, the filter paper is soaked with a coloring agent and quantified by light reflection.
