Premium Laboratory-Grade Filter Paper

Crafted from pure cellulose fibers for superior particle retention and high flow rates. Acid-washed and ash-free (0.06% max ash content) to prevent contamination in sensitive experiments.

Precision-Cut Round Design

185mm diameter (18.5cm) with laser-measured edges for perfect funnel compatibility. Uniform porosity (medium-fast flow rate) ensures consistent filtration results.

Multi-Application Performance

Ideal for chemical analysis, environmental testing, and educational lab demonstrations. Withstands temperatures up to 120°C for hot filtration processes.

Bulk Supply Advantage

Direct factory pricing for scientific institutions and schools. Ships in moisture-proof packaging with 100 sheets per stack, ready for high-volume usage.

Quality Compliance

Meets ASTM E832 and ISO 9001 standards for laboratory materials. Acid/alkali resistant for use with most common chemical solutions.
