Qualitative Filter Paper, Slow, 2-4 um, 150mm, 100/Pk SKU: CF15056

Qualitative Filter Paper - CF15056

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. 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

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Designed for analytical procedures where achieving the finest possible retention justifies the slower processing throughput.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. 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.
