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

Worked as described

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

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

Quality on these is great. I only gave it four stars though because they really need to make these .22 UM PES in 25MM instead of just 33 33 is just too large for what most people need them for They would make a lot more money if they made a 25

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

Works very nice will order these again, though maybe a larger micron size because these do clog fairly rapidly so i consider them a one time filter because of how fast they clog, but if you really want to push it, i was able to filter 75ml through one before it became too clogged to continue to work.

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.
