I get my test in both 5 and 10ml bottles and upon emptying them I find there is always just a little that I can't get with the needle. I save these bottles waiting for a way to get those last drops out. Is there a needle long enough to reach the bottom of the bottles or a trick that you guys know of to get it all out? An 18 gauge just doesn't reach the bottom of these bottles. It looks like I could get at least 1/2cc worth out of 6 emptys that I have saved. I hate to waste any juice. Ideas anyone?
