Grade 1 Qualitative Filter Paper, Standard, 32mm Circle, 100/Pk SKU: 1001-032

Qualitative Filter Paper - 1001-032

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. To this end, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Nominal retention of 11um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Nominal basis weight of 87g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

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. Meeting this challenge, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
