Hanna Low Range Reagent A

[kevin318]

Does anyone know where I can purchase Hanna Marine Nitrate Low Range Reagent A (H1781A-0) only? I run out of Reagent A before anything else and after a year and a half of using the Hanna Low Range Checker, I would really like to just purchase a bottle of Reagent A.

Thanks in advance.

Everything I've found seems to include the packets as well.
