Wanted - test tube from no-longer-used D-D/Merck phosphate test kit
 

So I guess the Deltec/D-D/Merck/whatever it's called "High Sensitivity" Phosphate test kit has been discontinued.

Mine's not done in the reagents but I broke one of the vials/tubes.

Anyone have an old version that they can spare one of the tubes? It's a nonstandard size so you can't use a tube from a different brand test kit, the colour density won't be right.

doesn't that one come with two tubes? I never use the one for the control anyways.
