Grade 2 Qualitative Filter Paper, Standard, 240mm Circle, 100/Pk SKU: 1002-240

Qualitative Filter Paper - 1002-240

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. In practice, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Ash content of 0.06% provides the documented blank value specification that quantitative analytical methods require.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Unmodified cellulose surface provides natural hydrophilic properties for rapid wetting in aqueous filtration applications.
• Non-strengthened grades deliver consistent retention at the economical price point that high-volume routine methods demand.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. Meeting this challenge, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
