Hey guys. I typically purchase Nalgene MF75 Complete Sterile Filter, 150mL, 0.22um/50mm dia. from Medical Lab Supply, but they have been out of stock forever.
My last order, I bought .2 micron filters… And it took over an hour to filter 25 mL of product, even at a low PSI and the unit on the bottom to catch the filter product begin to crack.
I've searched and searched and searched and cannot find the .22 µm filters anywhere… Any tips?
They have plenty of the .45 µm filters… But I have read that those are not advisable to use because they will let some bacteria through.
I'd really rather not order the point to micron filters again if I can avoid it… Because of how quickly they crack and the time that it takes to use them, it almost seems like a waste of money.
