Grade 230 9cm 50/Pk SKU: 5230-090

Qualitative Filter Paper - 5230-090

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Accordingly, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Nominal basis weight of 123g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
