I am fortunate enough to work at a lab with a VERY accurate balance. The balance is accurate enough to measure 71.2mg of baking soda which when mixed with 1L of water will give you a liter 4KH solution to use in you drop checkers. It'll last you a long while. It I get swamped with orders I may ask for shipping money, but 71.2mg isn't going to cost much to mail

. PM me if you're interested.
