I just started using a new 2 oz bottle of the FAS-DPD titrating reagent, and I've noticed that when I turn the bottle completely upside down, a drop will quickly form and fall down into my sample without me squeezing the bottle at all. Sometimes it looks like a second one will also form and fall into the sample if I'm not quick at turning the bottle back upright. I hadn't run into this before; I've always had to apply at least a tiny bit of pressure each time to get a drop out. Is this normal, or is it possible that the dropper tip opening is a bit too large?
Thanks,
Greg
