Qualitative Filter Paper, Slow, 2-4 um, 110mm, 100/Pk SKU: CF15054

Qualitative Filter Paper - CF15054

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Particle retention rating of 2-4um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Controlled ash level at ≤0.15% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.
• Dense fiber structure provides maximum retention for analytical procedures where complete particle capture determines result accuracy.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. In this context, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
