| i use bottle top filters. the 500ml ones. Are they only good for 500ml worth of filtering?
also when i filter water based winny i make it a bottle at a time and use a whatman. How many mls would the whatman be good for? and would a prefilter lengthen the life? thanks. |
technically they are only good for 500ml, but i have squeezed a bit more out of them when in a pinch.
As for the winny, i don't filter anymore, but when I did, i would usually get about 100ml if I purged them with air and PEG each time i used them.
