Great product, Great price

First off, let me just say that I'm not using these in a biological lab, so I can not attest the sterility and lack of human genetic material.I use a cheap 1mL micropipette for general chemistry because it is easier to use over any available pump for glass pipettes. I don't usually do anything super exotic, so polypropylene is acceptable to me. My cheap micropipette is fairly precise and dispenses volumes that I work with, so this bag of tips is a win for me.

Need to know: these do not have universal fit. But if they sit right with what your pipe is giving out, they draw the fluids, hold 'em steady, and stream 'em right on out. No muss, no fuss, just a piece of plastic primed to help out.

These are 1000uL standard pipette tips for a scientific pipette. They fit our pipette and stay on when needed and pop off when released. Not much left to say about them.

Tips seem to be decent quality. Don't know about how "sterile" a giant bag of 500 will remain as they're used, but for non-critical purposes they seem fine.
