ive cleaned them with methanol, works fine.
i know where to get them cheaper, but you gotta buy in LARGE bulk, like 50-250 of em.

goto an auto parts store and buy gas line antifreeze, its called "heet" and comes in a yellow bottle. make sure it doesnt list any ingredients other than methyl acohol. thats methanol
i just draw the methanol up through and then suirt it back out a bunch of times, so it goes both directions through the filter. i change the methanol now and then so its clear and i can tell the filter is clean, then i wrap in tin foil and bake at 250 for 30min.
btw you shouldnt need more than 2 filters tops to do 40-50ml, either you should prefilter or let the fina settle longer, cause theres obviously too much junk in what your trying to filter,

try heating the fina right before you filter--it helps to make it push smoother instead of the drip, drip, drip of cold fina

I heard that there are no binders in finaplex-h this leads me to believe that the finaplex is not disolved completly. I did 10g big tren and after 2 days of sitting in solvent I had to crush what was undisolved ( most were disolved ) I was very impatient . I stired the gunk that settled at a few times over the nextday this was my baby..........then I set out to filter the desolved oil (not venting the collection vial.) this made filtering twice as hard as need be. whats the truth about the binders the manufacture says no binders ...........

the "binders" are methylcellulose.

Chix, thanks for the "heat" info. Will try. But at this point Im thinking I had a bad batch of filters. I ordered more from the original place and GPZ to see if there's a diff.
BTW the stuff was heated when I filtered it and was sent through three seperate coffee filters. Also, sat overnight.

strange, you shoulda been able to filter like 100ml w/ 1 filter fast if you coffee filtered and let it sit.
ive done the exper. where some batches are real easy and others are hard,

im not 100% sure, but they use it in oral pills, and it doesnt hurt cows when injected into their ear, but i just dont like the idea of that sludge in my muscles, but its prob harmless in lower amounts.
