How often you refresh your TF-100 reagent?

Hi all,

I want to know how often we need to refresh our TF-100 reagent. My last refresh was 2014 and i'm planning to refresh all reagents next year. My problem is some of the reagent still have 80% full. So do i really need to refresh all of the reagents?

Also how do you know your reagent is bad?
 
Reagents do expire. Taylor Technologies recommends, as a general precaution, replacing reagents more than one year old or at the beginning of a new testing season. Some reagents have a longer expiration date than others. Remember to store them properly. I would say if it is 2 years old-get a whole new fresh set of reagents.
