How many tests can you do w/ one kit?

[Flailing_Gypsy]

I'm about to order a mandelin reagent testing kit from TRIP in Toronto, Ontario for $25. Does anyone know generally about how many tests I'll be able to do with one kit? I'm trying to determine whether or not I should order more than one.

Thank you!

Around 20 drops (tests) per ml . Multiply by size of container in ml's.

how long do the reagents usually keep?

At least some months, but in my experience, keeping in the freezer, years. Basically keep it away from heat and light as much as possible.
