Grade 2 Qualitative Filter Paper, Standard, 55mm Circle, 100/Pk SKU: 1002-055

Qualitative Filter Paper - 1002-055

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. In effect, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• At 97g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. To that end, 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.
