Description
Hawach Scientific Co., Ltd BIO-5 filter paper is a star product equivalent to Whatman’s Grade 5 with more competitive price, which has a high retention rate and slow flow rate (2.5μm). Because the material of filter paper is made of cellulose, its surface has numerous micropores for liquid particles to pass through, while larger solid particles cannot pass. This property allows the separation of liquid and solid substances that are mixed together.
Features
Suitable for samples with small Rf values and developers with low viscosity, but with longer deployment time
Pore size 2.5μm with high retention and slow flow rate
Disc and sheet type, regular size or customized size and shape are all available
Micropores, small pore size, a large number of perforations
Fine particles are filtered on the surface, airflow is smooth, and the pore size is normally distributed.
Advantages
Passed ISO9001 and CE third-party certification
Uniform distribution of micropores
High purity and consistent performance
Lowest ashless content: < 0.1%
Full range of diameter provide
Applications
