I don't know. But if you know the volume you want to take, and you have a similar sized measuring spoon, you could callibrate by fillling the spoon with water, sucking it up with water, and seeing how much of the dropper it fills. Or how many dropper-fulls.sunmountain said:post 103636 The dropper is ungraduated. Does anyone know how much 1ml is from the dropper?
I mix my B-vts with water, but I make it easy for myself by adding half a litre of water, and taking 30ml morning and night for 8 days. I've had some fairly low doses, like 1/64 tsp split into 16 doses (ie 1/256 tsp =~0.02ml).
