Used it for my testosterone which had chunks of the rubber stopper inside it. It filtered everything out and I didnt need to replace my vial

So yes I bought this with intentions of IV use of my oxycontin, before I used these filters the shot had fillers in it and made it look the color of the pill, now it filters out and it's clear and pure compound. I've noticed some are hard to push through, idk if it's an error on my end or if it's the filter. But majority of the time no issue.

High quality filters that twist and lock easily. Very simple to use, just push the liquid through them. You can even see what it filters out because the chamber where it keeps everything it takes out is transparent-ish. Would recommend.

Super easy attachment between the needle and the syringe.Functionality is spot on.All individually wrapped in a large bag.

I can't really think of one thing I really have positive to say considering there's much better filters (same diameter, also 0.22μm, same cost). All these filter are heavy particles. A coffee filter would do an equally sufficient job.I went through 4 and still didn't end up with the same quality results as with 1 filter vs the filters I normally use (which I'm able to use a few times if I really need to). I don't know why these have such high reviews, honestly. They do not filter properly, period. This wasn't a bad one or two.I really question whether it's filtering bacteria and other particulate, dyes, etc. that it should be able to. These are incapable of removing the color from what I filter after 4 filters, and those are larger molecules than bacteria. I've been using filters like these in all different brands for about 10 years and I think these are by far the absolute worst I've come across. I had to get right back in on here and order the ones I would normally. So a waste of money, useless, and potentially dangerous depending on what you use it for.The only reason I'm bothering to review these is because they have great reviews for some reason and I noticed some people are trusting these to filter for IVDU. These are dumpster material. You are not getting all that you think you are getting out.The white plastic ones really any brand on here are so much better.

These are great for laboratory use. They appear to filter out the smallest particles (the color of the substrate is clear upon filtration), but I would recommend double filtration just in case. I have no scientific data supporting this but on the off chance you get a bad batch of filters, well it’s better to be safe than sorry. I’ve used these numerous times and so far they have been a success. These are a must have if using in a laboratory to filter out unwanted BINDERS from sticky products. Better to err on the side of caution. It can get pricey yes, but it beats the alternative. IFYKYK. Stay safe out there, practice good hygiene!

My students use these filters for the lab for antibiotics and other heat sensitive solutions.They are easy to use. Have purchased these multiple times.Highly commend.

I work at a safe injection site. I handed this out to service users who inject pills with lots of additives in them to see the difference between standard cotton filters and these guys. The liquid they pushed through was perfectly clear of any dangerous filler! Will definitely purchase again!
