I use a sanitized turkey baster to pull out my samples, if that helps you any.
Yep. Don't use your bubbler to read your beer.
You can get samples pretty easy. I use carboys as primaries all the time
just fill my racking cane with tap water, put my thumbs over the ends, carry over to the carboy, drop the cane into the middle of the brew and drop the other end into a small SS pot to collect a cup or so. Takes about 60 seconds.
