Hanna phosphate regents exp. date

[mheaven]

Hello everyone, the Hanna phosphate regents come with an expiration date.

Has anyone used them past the date?
Do they're really expire or is this just another way to get you to buy more every year?

I have about 80 left from when I purchased my Hanna meter and would hate to throw them away if I could still use them.

Thanks,
Danny.

Want to send me a few I can test them out for you compared to mine.
