Biomed ScientificSyringe Filters PVDF 13 mm Diameter 0.22 um Pore Size Non Sterile Pack of 10 pcs

I rec'd an email frpm Biomed saying they'd appreciate my opinion in product review & in turn I'll get a 99% off coupon for my next purchase. So, I may being paid for this but rest assured I'll be brutally honest.I bought these September 6th, 2018 & the quality of this product is astounding, No BS! I started taking my pain medication intravenously about 5 months ago, July_ish specially for the 8mg Dilaudid. After the CDC crackdown opiates the majority of my medicine was reduced down about at a 90% drop of what I used to get. Been on them for many years. But, w\the crackdown, I had to find a better way to manage my pain. Prior, I was @ around 85% relief & Post, I was maybe around 15%. The Bioavailability of IV'g my medication was 100% so my choice was clear. I then launched a research campaign on Bluelight.org "a lot" ~ I mean "a lot". Part of my researched told me to get the Syringe Filters PVDF 13 mm Diameter 0.22; that it help pack a punch w\my medicine when I ROA it via IV. Boy were they right! Had to watch a lengthy video on YouTube to learn how to use them but I was pleasantly surprised with the outcome. Thank you Biomed for helping me better manage my chronic dibilitating pain. You guys Rock!

I have purchased 3 packages of these. All 3 of the packages had one broken/defective filter in them.

I attempted to filter a liquid four times using the above filters. I used very little pressure, and the filter blew out. Each time I used less pressure and was getting a drop out every 6 to 10 seconds. After about a minute the drops reduced to about one every 10-15 seconds using the same pressure (Like the weight of my hand and first then the weight of my finger) a slight deviation in pressure and the filter blew outI purchased to filter a very light liquid oil which is totally out of the question if the filters can't even filter a liquidsave your money

Garbage. These are tiny compared to the other wheel filters sold on here. Also they do not screw on tight. While filtering a particularly cloudy solution the filter couldn’t take the pressure and flew off into the filtered solution below spilling everything in the process.

No complaints.

I like that it came in packs of 10.
