Grade 595 Qualitative Filter Paper Standard Grade, Circle, 110mm, 100/Pk SKU: 10311610

Qualitative Filter Paper - 10311610

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Consequently, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Rated at 4-7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
