Alk reagant, see through bottles?

[badfinger]

Is there a reason you guys don't use a see through bottle for your reagents?

I am just getting through my first bottle but not sure how many tests I have left. Was I supposed to keep count?

I think a see through bottle would be a big help.

Thanks

I believe the reagent may be light sensitive, which would be the reason for a dark bottle.

This is correct!
