Grade 1 Qualitative Filter Paper, Standard, 20mm Circle, 400 pack SKU: 1001-020

Qualitative Filter Paper - 1001-020

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. With this in mind, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Standard construction delivers adequate wet strength for conventional filtration while maintaining economical cost for routine applications.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Basis weight of 87g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Nominal ash content of 0.06% ensures minimal inorganic residue after ignition, protecting the accuracy of gravimetric determinations.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. For applications like these, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
