Grade 201 Cellulose Filter Paper, 15cm Circle, 100/Pk SKU: 5201-150

Qualitative Filter Paper - 5201-150

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Standard cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Nominal basis weight of 75g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
