A commercial coffee filter sitting on top of a #1 Whatman lab filter, in a Buchner funnel.
The coffee filter protects the lab filter from blinding and you can gently brush the coffee filter surface with a small paint brush while filtering, and it will keep the pores open longer.
Am looking to understand what is a #1 Whatman lab filter and which Buchner funnel is better to combine with it.
Any suggestions is more than appreciate !
P.s. How is it possibile to replace the coffee filter? A 125 micron iron sieve mesh will be ok?
