Grade 3 Qualitative Filter Paper, Standard, 23 mm Circle, 100/Pk SKU: 1003-323

Qualitative Filter Paper - 1003-323

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Standard wet strength is sufficient for conventional Buchner funnel and gravity filtration setups at moderate sample volumes.
• Particle retention rating of 6um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Controlled ash level of 0.06% meets the blank value requirements of quantitative methods where filter contribution must be documented.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. With this in mind, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
