Grade 201 Cellulose Filter Paper, 24 cm Circle, 100/Pk SKU: 5201-240

Qualitative Filter Paper - 5201-240

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.

When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. Standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
