I have a medicine dropper that measures in ml from 1-5ml that I use for smaller stuff, and I have a turkey baster (that I heated the end and smashed some so that when I pick up fluid it doesn't dribble out in the air) that I can pick up as much as 25ml at a time. the turkey baster actually has some measurements on it but I marked it with a sharpie so that I can pull out 10, 20, and 25ml in one pull with it. And it is long enough to reach to the bottom of my 4liter nute containers.
