filter question

[modestmuscle]

My buddy was wondering on average what is the typical lifespan of a whatman filter? Roughly how many mL can pass through it before it needs to be discarded? Thanks for any info

I believe between 50-100 ml.

Depends on brand of syringe filter, carrier oil, and of course purity of raw.

I've seen them clog enough to the point where its too much of a pain in the ass to use after 10cc but I've also seen them do 120cc. All in all syringe filters are a pain I think, bottle tops are much easier.
