Syringe Filters PTFE Membrane - 13mm Membrane Diameter ,0.22um Pore Size,Pack of 100

Good product, recommended

The one's that burst open under the same pressure that is well below the listed upper tolerance range. I have had A LOT of invaluable materials go blasting all over the laboratory, making a mess and worse, contaminating the research I've been working on for however long that day. I would estimate conservatively that at least 1 in 10 burst open at the welded seams of the disks. The others were fine except for the ones that were junk because they would not connect to the luer lok end of the syringe- they start on the threads but then they don't stop, rather, suddenly feel loose and keep spinning (like a stripped thread on a bolt) but when I replace it with another on the same syringe, it threads together perfectly. And yes, I know I have not "over torqued" them - It happens at a very low threshold of pressure from my fingers and well before the point where they ever stop tightening. I have been doing this a long time-- 27 years and counting- I can safely say that ⅓ of the 100 pack was junk- and at least 10 of those were destructive due to the 1st listed cause.Have switched brands. No longer have had these problems...

These things are terrible. It's like 70/30 if they don't explode under minimal pressure causing your mixture to spray everywhere. I thought the 1st container was many a bad batch then this one was way worse.

Not useful
