Quantitative Ashless Filters Paper is specially designed for precise analytical and gravimetric procedures requiring minimal residue. Manufactured from high-quality cellulose with virtually no impurities, this filter paper burns to an extremely low ash content (typically <0.007%), making it ideal for use in critical laboratory applications involving ashing and quantitative analysis.
It features a strong, consistent texture for uniform filtration and excellent wet strength to withstand vacuum filtration and heavy sample loads. The controlled pore structure ensures high retention efficiency for fine precipitates while maintaining reasonable flow rates.
These filters are widely used in chemical analysis, environmental testing, food and beverage quality control, and sample preparation where analytical accuracy is essential. Available in multiple grades, they meet the stringent requirements of ISO and other international standards for laboratory filtration.
