Grade 2 Qualitative Filter Paper, Standard, 580x680mm Sheet, 100/Pk SKU: 1002-931

Qualitative Filter Paper - 1002-931

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. Each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Nominal ash content of 0.06% ensures minimal inorganic residue after ignition, protecting the accuracy of gravimetric determinations.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Nominal basis weight of 97g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. In these cases, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
