产品型号: 62-6176-12
产品品牌: Cytiva (Whatman)
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.
- Note: This is for testing and research purposes only.
