In line with what bobby_m states about evaporative concentrations, I have noticed that if you are reusing the same spoon/tool for your samples then you need to make sure and rinse/dry it between uses because during the time between samples the wort can evaporate its liquid component leaving a high-sugar concentration dry layer on the spoon. If this same spoon/tool is quickly dipped for another sample then that high-sugar layer goes back into solution to create a higher-than-actual wort sugar concentration leading to increased refractometer readings.

Well i have noticed that any and i mean any particles like hops or grain pieces are in that little drop it throws off the entire reading. It's to much of a pain in the ass to use because of that. But maybe i am doing something wrong? i just pull a little and chilled to desired temp and take a hydro reading. Works every time. refractometer was a waste of $$ for me

Well, it depends on how you look at refractometer use. I use it during fly sparging to make sure I'm not oversparging. There's no way in hell I'm going to keep collecting 3 ounces and putting it in an ice bath for 5 minutes a bunch of times during the sparge. Even if the instrument is giving me slightly skewed readings at this stage, I'm looking for approximately 3 brix or 1.010 to know when to stop. I don't care if it's 3.4 brix or 1.008 actual.
