Whatman Glass Microfiber Filter Paper has a capillary fiber structure that absorbs more water than an equivalent cellulose filter paper, making it suitable for spot analysis and liquid scintillation counting methods.
- High flow rates, low resistance and high particle loading capacity
- Nominal particle retention of 2.7 µm
- It is an ideal pre-filtration product, which can significantly increase the filtration capacity.
- It can be used are chemically inert separators where strong acids or alkalis are used as electrolytes
- High temperature resistance
