Grade 2 Qualitative Filter Paper, Standard, 460x570mm Sheet, 100/Pk SKU: 1002-917

Qualitative Filter Paper - 1002-917

Pre-filtering turbid samples before instrumental analysis needs a paper grade that removes interfering particles while maintaining reasonable flow rates. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Altogether, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Nominal basis weight of 97g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. Rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
