You can use up to 100ml and sometimes more, in a single 25mm AQ™ syringe filter is you are using an aqueous solvent and your sample is not cloudy.

However, the best way to determine if a filter should be replaced from service is when you get a very fast drop in back pressure or a constant rise in back pressure. Both indicate it is time to replace them. Reusing the same syringe filters for multiple samples is never recommended due to carry over problems.
