功能

• Harder and sturdier than ordinary ash-free quantitative filter paper
• Acid-cured
• Has high wet strength and chemical resistance. Acid-cured treatment keeps ash at a low level. The surface is strong and suitable for various types of microanalytical filtration.
• Filter paper with high particle retention even under severe conditions. The filtration speed is low. It has high chemical resistance and is often used to weigh metals.
