FAQs

1. What is the material composition of the Whatman WME WH GR membrane filter?

It is made from mixed cellulose esters, providing a balance of strength and filtration efficiency.

2. Can this filter be used for sterilization?

While it can retain bacteria, it is not rated for absolute sterilization; use a 0.22?m filter for sterilizing applications.

3. Is this filter compatible with organic solvents?

It has limited compatibility; avoid strong solvents like acetone or DMSO, but mild solvents may be used.

4. How should I store these filters to maintain their quality?

Store in a cool, dry place away from direct sunlight and moisture to prevent degradation.

5. Are there alternatives for higher particle retention?

Consider Whatman?s 0.2?m or 0.1?m filters for finer particle retention in critical applications.
