Grade 1575 Qualitative Filter Paper Wet-Strengthened, Circle, 200 mm, 100/Pk SKU: 10314916

Qualitative Filter Paper - 10314916

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Ultimately, 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.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. For applications like these, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
