Quantitative Pyramid Filter Papers, Grade 540, 11cm, 100 pc SKU: 1540-10124

Qualitative Filter Paper - 1540-10124

Pre-filtering turbid samples before instrumental analysis needs a paper grade that removes interfering particles while maintaining reasonable flow rates. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. In combination, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Chemical hardening of the cellulose fiber matrix provides the durability needed for quantitative procedures involving hot or corrosive reagents.
• Particle retention rating of 8um defines the separation threshold for the application, determining which solids are captured and which pass through.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
