Grade 113V Pre-Pleated Filter Paper, Wet-Strengthened, 240mm Circle, 100/Pk SKU: 1213-240

Qualitative Filter Paper - 1213-240

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Wet-strengthened construction provides the mechanical durability needed for technical filtration applications under sustained vacuum.
• Basis weight of 125g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Nominal retention of 30um provides the particle size cutoff appropriate for the analytical or preparative separation method.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. For this purpose, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
