FAQs
What is the shelf life of Whatman ME25/31 Membrane Filters?
When stored in a cool, dry place, these filters typically have a shelf life of 3-5 years. Always check the packaging for the exact expiration date.
Can these filters be used for sterile filtration?
Yes, the Whatman ME25/31 is suitable for sterile filtration when properly autoclaved or used with a sterile technique.
What is the maximum temperature these filters can withstand?
These cellulose nitrate filters can handle temperatures up to 120°C, making them suitable for most lab applications.
Are these filters compatible with organic solvents?
While they work well with many solvents, cellulose nitrate filters may degrade with strong organic solvents like acetone or DMSO. For such applications, consider PTFE or nylon filters.
How do I know if I need a 0.45µm or 0.22µm filter?
A 0.45µm filter is ideal for general particle removal and microbiological testing, while 0.22µm is used for sterilization of liquids. Choose based on your specific protocol requirements.
