At 25 tests you are not going to finish this box before the printed date, so most of it will be past date by the time you get to it. That is exactly why it is marked down.\u003c\/p\u003e\u003cp\u003eHanna prints an expiration date and lot number on every component for traceability. Reagent past its date is not dangerous and does not spoil in any dramatic way, it simply loses potency over time, so readings can start to drift low. This is a good buy if you want an inexpensive spare kit, if you are testing often over the next few weeks, or if a little drift does not matter for what you are doing.
