question, hanna phosphate checker

[PEP12]

With regard to the phosphate reagent has anyone noticed that some packets seem to have a smaller amount contained in them or am i just imagining it ?

I never noticed an issue using them over the past year. My only thoughts would be a concern that the contents were exposed to moisture or perhaps if they were expired and the reagent degraded.

I haven’t noticed it as such, but just try flicking the packet a few times before opening it to make sure non of the power is stuck in the corners etc.
