Sterile Syringe Filters PVDF 25 mm Diameter 0.45 um Pore Size Individually Packaged 10/pk by Biomed Scientific

These were very easy to use and worked perfectly. The biggest reason I ended up choosing these was because they are sterile. I noticed in some other options for this type of product they were not, although they don't make it obvious, and I feel that you usually assume things of this nature are going to be sterile. It felt like searching for and reading the fine print. Make your own decision as to how that makes you feel if any way at all. Myself, I felt more trusting of these and at the end of the day, my personal reasons for choosing this product aside these just plain worked and they worked wonderfully. I will definitely be purchasing more in the future.

These are great sterile syringe filters. They leave you with a sterile clean sample. I am completely satisfied with their performance and I will be purchasing them again. I only wish they sold them in larger quantities. I highly recommend them.

Works great for my purposes. I don't use enough to warrant a 50-100 pack, so it's nice they're offering in 10's Never had a problem with these and shipping is on time and depenable. When these aren't available I've ordered the PTFE and the PES versions which have also been good. I like using them fo filter my solution into a sterile 10ml vial.

I was a little worried about the exit Port not being lure lock but everything worked great and went well no leaking issues or anyting and you can actually see some of the stuff that got filtered out in the filter

Filters worked good but for my use, they may have filtered too good. If you are looking to get the highest level of filtration, these are the ones to use!

like the 0.22 micron variety, these filters fit well and do not leak at the seam like some others. they are good for filtering out large particles and binders in a project where tablets are used before the final sterile filtration. As a sidebar, trying to bypass the 0.45 micron step only yields frustration and usage of many 0.22 micron filters.

Goods arrived in good condition.I bought a pack of 10, I tried two filters, but the clear liquid simply would not go thru; not a single drop, even under great force for more than 3 minutes, and finally, I changed the filter to the more expensive "Whatman" brand filter, and it ran thru without any issue.Could I return the remaining 8 and get a refund?

So ive used these before, no issue, same viscosity and chemicals used. This batch they were all clogged. But if youre in pinch like me and need to make it work. If you push on the syringe for like 5 minutes(careful not to break the filter) it will eventually filter. Not sure what the issue is but I got one of them to work so far. Im curious if its filtering more or less than the lass batch lol.
