FAQs
1. What is the material composition of the Whatman ME25/20 membrane filter?
The Whatman ME25/20 membrane filter is made from mixed cellulose esters (MCE), which provides a balance of strength, chemical compatibility, and low extractables.
2. Can this filter be used for sterilization applications?
While the 0.45µm pore size is commonly used for general filtration, sterilization typically requires a 0.22µm filter. Always verify the specific requirements of your application.
3. How should these filters be stored to maintain their performance?
Store the filters in their original packaging in a cool, dry place away from direct sunlight and moisture to prevent degradation or contamination.
4. Are these filters compatible with organic solvents?
Mixed cellulose ester filters have limited compatibility with some organic solvents. Check the chemical resistance chart for your specific solvent before use.
5. What is the difference between ME25 and other Whatman membrane filters?
The ME25/20 series is optimized for general filtration with a focus on high clarity and low extractables, whereas other series may prioritize different properties like protein binding or solvent resistance.
