Grade 93 Qualitative Filter Paper Wet-Strengthened, 58x58mm Sheet, 500 Pk SKU: 1093-930

Qualitative Filter Paper - 1093-930

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Because of this, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Basis weight of 65g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Rated at 10.0um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Wet-strengthened fiber matrix withstands extended contact with aqueous solutions without the disintegration that limits untreated papers.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. In these cases, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
