Grade 802 12.5cm Diameter 100/Pk 100/Pk SKU: 5802-125

Qualitative Filter Paper - 5802-125

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Accordingly, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. In these cases, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
