Syringe Filters PES Membrane, Sterile, 33mm Diameter, 0.22um Pore Size, Hydrophilic Filtration, Individually Packed, Pack of 10

These filters are very good. They seem to have good flow while clearing out lots of contaminants. I highly recommend them.

Worked as described

Great for when you need to filter multiple peptide vials in a row, or if the smaller 4mm ones get plugged up too quickly.

Best filters I’ve founds. Filters large amount per filter.

Quality product but leaves a lot of peptides and liquid in the filter. If using with only a few milligrams of stuff, get a smaller size.

These Locofiltr Syringe Filters work exactly as I hoped. The 0.22um PES membrane filters my aqueous samples smoothly-no clogging, and the sterile individual packs save me time (no extra sterilization needed).They fit all my standard syringes, and the hydrophilic design makes liquid flow easy. For a 10-pack, the quality is great, and it's cheaper than some big-name brands I've used. Will absolutely buy again for my weekly lab task

Works exactly as described. Takes some of the “spice” from the injections. I was worried about the friction fit, but fits well and stays better than expected. It just does not twist lock on.

everything works as it should
