Qualitative Filter Paper - 10314726
Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. Accordingly, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.
Key Filter Paper Characteristics
- At 12-25um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
- Unmodified cellulose surface provides natural hydrophilic properties for rapid wetting in aqueous filtration applications.
- Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
- At 88g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
- Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. To meet this need, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
