Filter Paper Grade B15540

•Hardened ashless filters (ash content approx. 0.003%), especially recommended for filtration applications requiring vacuum and pressure filtration, and for the use of acidic and alkaline solutions.
•Made of super-refined cotton linters and cellulose
•Acid-washed and free of minerals and metallic ions, ideal for the detection of metallic ions
•Very high wet strength; easy to scrap off or wash off precipitates Hardened by small quantities of nitrogen-containing resin, which does not introduce significant impurities into the filtrate
•High resistance to aggressive chemical components, like sulphuric and nitric acids (up to 40 % at 50 ? Celsius) and alkalis (up to 10 % at 20 ? Celsius)
•For analytical applications, routine quantitative and /or gravimetric procedures
