Highlights from this day
  • still_here_2024 — i have never regretted spending the money on a test. i have regretted not testing twice 09:25
  • group_buy_gwen — is it worth testing if the vial has already been through a warm transit 09:45
  • group_buy_gwen — weigh the vial before you reconstitute. it costs nothing and catches the common failure 09:56
  • endotoxin_ed — underfill is more common than impurity. if you only test purity you are testing the less likely failure 10:34
  • endotoxin_ed — i had a result i am fairly sure was a handling error on my side and i logged it as such 11:13

weigh the vial before you reconstitute. it costs nothing and catches the common failure

anyone tested the same lot twice at different labs

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