Laboratory Filter Papers For Analytical Filtration
Laboratory filter papers are used where laboratories need consistent separation of solids from liquids or gases during sample preparation, testing and analysis. The visible range includes Advantec qualitative filter papers, ashless quantitative filter papers, glass fibre filters, quartz fibre filters, low absorption filters, high wet strength filters and specialty filter circles in multiple diameters and pack sizes.
How To Choose The Right Laboratory Filter Paper
- Filter type: Choose qualitative filter paper for general sample clarification, or quantitative ashless filter paper where low ash content is needed for gravimetric analysis.
- Retention and flow rate: Match the grade and particle retention rating to the method, including fine retention options under 5 μm and medium or fast qualitative grades.
- Diameter: Select the filter diameter to match the funnel, holder, filtration apparatus or sampling device, with common sizes including 9 cm, 47 mm, 90 mm, 125 mm and 150 mm.
- Material: Use cellulose papers for routine laboratory filtration, glass fibre filters for high loading and prefiltration, and quartz fibre filters for high-temperature or acidic gas sampling applications.
- Application conditions: Review wet strength, binder status, trace metal suitability, temperature exposure and chemical compatibility before purchase.
Applications Across Laboratory, Environmental And QC Testing
Laboratory filter papers support workflows across Environmental, Life Science and Diagnostics, food testing, research, analytical chemistry, quality control and industrial testing. Common uses include sample clarification, precipitate collection, air and water pollution monitoring, gravimetric analysis, prefiltration and preparation before downstream measurement.
