Hydrophilic PTFE Syringe Filters 25mm Diameter 0.22μm Pore Size for Laboratory Filtration by Allpure Biotechnology (Hydrophilic PTFE, Pack of 100)

These seem to be very high quality. They work well. You need to push the material through slowly, but that is to be expected with such a fine filter. They fit onto the luer lock syringes I have perfectly. They're not individually packaged, but I'm not sure how much that affects their sterility. Overall, I would recommend.

They work well so far. I've used about 12 of them and so far no complaints. I'm purifying plant matter.

Quick shipment, exactly as described.

Then this is THE solution for your solution! These syringe filters look fresh and are mad decent.
