10 Pack Sterile Syringe Filter PES Hydrophilic Filtration 0.22um Pore Size, 33mm Diameter Membrane Sterile PES Membrane Individually Packed by Finetech Made in Taiwan

Didn't filter like a pvdf filter would so not sure why it's so popular. Both types of filters get "stuck" kind of Pro tip: slowly pull the plunger out and put it back in, repeat this slowly a few times and you'll get more vlowuis out of it. Obviously don't force it or it'll pop. Actually I prefer PTFE filters over pes it's that bad. Also don't go for anything like .1 micron, it just won't work for liquids .22 micron is the smallest and best and for liquid filtering small amount like 1-5mL etc Also don't go for 13 mm either that also is too small, stick with 25 mm for smallest width. It's too bad they're all made in china now a days but the machines that make the wheel filters are automatic so guess it doesn't really matter. Like if u didn't have a sterile pvdf wheel filter at .22 micron and 25mm but u had some that weren't sterile u could start with that then pour into this product sterilizing it, it won't really filter it more though of particulates. 3/5 for a wheel filter
