Feature: filter diameter: 25mm, pore size: 0.45um, membrane material: PES , hydrophilic property .
Syringe filters are made of inert plastic house, membrane, and luer lock fit. It is used with disposal syringes or filtration device with luer fit.
Syringe filters are often one-time use only.
Having low affinity for proteins and extractable. Substantially faster filtration rate than PVDF membrane.
Biomed Scientific syringe filters offer universal application for analytical procedures.
Hydrophilic PES (Polyethersulfone) suitable for pre-filtration and filtration of buffers and culture media .
High flow rates; Low protein binding; Low concentrations of extractable substances; Excellent chemical stability; High thermal and oxidative stability.

Does exactly what it's supposed to, and if you're removing particulate from solution, these are the best of the best. The flow on both the smaller and larger size of the green models is far superior to the red ones, and as I understand it, the green ones remove much more troublesome bacteria and such from the solution.A blessing to have on Prime for the price being asked.

- These filters are excellent for filtering home mixtures and solutions via a syringe attachment. I NEVER prepare a solution without these anymore, & have never had an issue since. A little money now saves misery later.- Studies have shown (can search online) these filters filter out 100% of endospore forming bacteria that are common and can cause infections and abscess. These 0.22um filters are the size that should be used. The Endospore bacteria are found to be no smaller than 0.8um so these filter them 100%. Also the PES is found to not filter any of the "active compound" itself. The loss that can occur is that a drop or two may remain in the filter unit though I HIGHLY caution against forcing air through to produce those remaining drops. A burst of a few foamy drops can occur which is the residual particulate and filtrate being pushed around the sides of the filter. It's not worth the couple drops, or a small amount of water can be passed through slowly after.- The studies shows less fluid remains behind with the size 15mm or 13mm diameter filters than with the 25mm, though I prefer these larger 25mm. More surface area to filter which clogs slower and can be reused several times (the 25mm are rated for 10ml to 100ml total fluid filtered. Whereas the 13mm are rated only for 0ml to 10ml. Definitely a better value with these 25mm diameter filters).- A last note, do not use PTFE filters for fluid preparations in syringe. PTFE are hydrophobic and best used for gas exchange filtration. And the Nylon can tend to bind protein and amino acids which can result in filtering a bit of your "active compound". Use the PES only. These PES filters are really the best for home filtration of syringe fluid preparations. (poppy).

Very reliable and affordable filters. They are of excellent quality, and get the job done nicely and efficiently. Well packaged for shipping, and nice to have 2 day shipping available. Very satisfied, will order again.

I have witnessed this used to filter BTH with miraculous results. Wouldn't do it any other way now.

I've only had these a short while, but so far they're working exactly as advertised. Everything arrived in pristine condition with no packaging issues. Couldn't ask for more!
