The filter’s core strength is its powerful speed and durability. It boasts a Fast Flow Rate (39 s Herzberg) and Coarse Porosity, coupled with excellent retention of 20-25 µm particles. The low ash content (0.015% maximum) ensures accurate weight measurements after combustion. Furthermore, the hardening process minimizes fiber shredding and provides chemical resistance, ensuring a clean and reliable separation every time.
Features:
- Hardened, acid-treated paper with high wet strength, ideal for vacuum filtration in Buchner funnels
- Low ash content (0.015% maximum) suitable for quantitative gravimetric analysis
- Coarse porosity and Fast Flow Rate (39 s Herzberg) for maximum throughput
- Excellent retention of coarse particles and gelatinous precipitates (20-25 µm)
- Hardened to minimize fiber shedding during collection of precipitates
- Resistant to chemicals for increased durability
