What measurable amounts do testing spoons have?

[ZoWhat]

Please see the attached image on these small spoons that come in Red Sea and Salifert test kits.

What measurable amount do these spoons hold? Like in milligrams or in teaspoon-fraction?

Weight we would obviously depend on what's being measured. Volume I don't know but it's a very small amount. Have you thought of a new use for them?

New use would be measuring out trace elements...in powder form

It might work for making a stock solution to dose, but not for actual direct powder dosing. I think it is still too big for that.

Yes! Exactly what I want to do Randy. Use it to make some trace elements in 16ozs of RODI

How did you convert sugar granules to mL? Using a larger measured volume and a scale?

Wouldn't it just be easy to get the 1ml syringe in test kits and fill the spoon up with water? that will give you the volume

Details on what I did. Which prob WRONG. I'm not a chemist by all means..

I have a 1/2 teaspoon that labeled 2.5ml

I perfectly leveled 18 scoop of sugar using a razor blade using the white spoon above.... to perfectly level the 1/2ts (2.5ml) spoon

I took 2.5ml and divide by 18 to arrive at 0.13888ml and rounded to 0.14ml
