I have noticed that when using the sample sizer for 10ml that I get a "dome" of water at the top of the test tube.
I was wondering if other sample sizer users shake that off or leave it?
I noticed that if I leave it, the sample is just above the marking on the tube, if I shake it off the level will be just below the marking.
To get consistent results I have been leaving it.
I know it's a small amount, and most likely trivial, I'm just curious how others go about this.
Here's a pic of that "dome" of water.
