Quantitative Filter paper is used for precise quantitative analysis to detect types and amounts of materials in analysis samples.


Quantitative filter paper is made of refined pulp with almost 100% alpha-cellulose and has less than 0.1% ash contents.
To meet high purity for quantitative analysis, it is washed with acid. Available in most sizes. HM maintains the highest quality in accordance with ISO 9001:2008

※ The pore sizes are indicated in accordance with the test methods selected by each filter paper manufacturer.
Thus, filtration performance may be the same, even though pore sizes are different with those of others manufacturers.

• Basic Weight (g / m²) : In accordance with DIN EN ISO 536, The test is performed with filter papers from 500cm² to 1,000cm²
• Thickness (mm) : In accordance with DIN EN ISO 534, the value measured with a thickness measurer under the pressure of 10N / cm²
• Herzberg( s /100 mL) : Fold a filter paper with a diameter of 110mm in quarters and soak it. Then, hang it and filter 10mL of distilled water at 20°C. The time that it takes for filtration is measured.
• Retention rate (μm) : Retention rate is calculated by test methods of filter paper manufacturers. As each manufacturer has a different test method, use these data for reference only.
• Ash Contents (%) : Weight of residues after 10g of filter paper is ignited in platinum crucible at 800°C

※  Qualitative filter paper is available in a roll type as well as a sheet type.
※   HYUNDAI MICRO provides a customized sizing service.

※ The table is for suggestions only. Filter specifications can be vary on its performances depending on the manufacturers.
