Sterile Syringe Filters PES 25 mm Diameter 0.22 um Pore Size Individually Packaged 100/pk by Biomed Scientific

These work great for filtering research grade peptides.

Great product quality, filter membrane is extremely strong and resilient to fine particulate and continues to function and provide sterile clear filtration with frequent use.

A good value... I use a large luer-lock syringe, and pull it all the way back which tends to give it the pressure needed to get the liquid thru the filter... I do think the PDVF and Nylon filters seem to work a little better, but they are all interchangeable, I think.

Each filter came packaged and sterile as indicated. They've worked perfectly, have not had any filters clog, bust, or leak. They work great, will definitely be purchasing more.

Did its job all right I suppose. Was about to order more but then it said my delivery wouldn’t arrive until June 20…… And that’s with an extra $10 shipping cost? All the other orders have came within a few days. What on earth is going on here?

Fits description and needs. Wrapped sterile

I dislike these! They break when you push fluid thru and some particulates still pass thru.

Individually sealed (sterile), these work very well
