Hi people. Today while shopping at c328 i saw some "tetra reagent refill kits" bottles. Probably for the people who bought the test kits and just want the reagents. So my question is: can we just purchase those refill kits without first buying the original kits? More cost effective I have to say. And since we can find the color charts online, all we have to get is the test tubes for ourselves.
Is there anything I am missing out here?
