Highlights from this day
  • ten_of_ten — i told QSC about a result they would not have liked and they did not argue. credit where it is due 22:25
  • lisbon_lot — coming back to this my read after three years of this: purity is mostly fine across the market and fill consistency is where suppliers differ 22:27
  • lisbon_lot — weigh the vial before you reconstitute. it costs nothing and catches the common failure 22:44
  • lisbon_lot — if you are testing to settle an argument you will not settle it with n of 1 22:55

quick one the results in this channel skew because people test when they are suspicious. that is selection bias and it is real

*that should say weekly

certificate said 99 and the independent came back 99.4, is that a problem

sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm

is a purity-only test worth the money if underfill is the common failure

is quantity testing available as a separate thing or bundled

i had a result i am fairly sure was a handling error on my side and i logged it as such, i could be wrong

post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later

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

a supplier disputing a result is rare here and it has never gone well for the supplier
