what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern

coming back to this whats the underfill rate people are actually seeing

the honest limits: hobby chain of custody is weak and any result here should be read with that in mind

i have never regretted spending the money on a test. i have regretted not testing twice

quick one is it worth testing if the vial has already been through a warm transit

Batch lookup G-0641: 5 independent reports on file, earliest 2025-09-03.

the results in this channel skew because people test when they are suspicious. that is selection bias and it is real, i could be wrong

do you test every order or sample it

underfill is more common than impurity. if you only test purity you are testing the less likely failure

certificate said 99.2 and the independent came back 98.1, is that a problem

99.4 against a certificate of 98.6 is fine. the same supplier landing low four times in a row is a question

i told QSC about a result they would not have liked and they did not argue. credit where it is due

unrelated but weigh the vial before you reconstitute. it costs nothing and catches the common failure, anyway
