The finger flick - an awesome lab trick! Finger vortexing & other mixing methods

Today’s lab trick, the finger flick! I learned from a mentor in undergrad, that flicking the bottom of tubes to create a manual vortex is one of the best ways to mix things gently. Just flick, flick, flick, then (typically) pulse spin in a microfuge to draw that flicked liquid down to the bottom of the tube. Microfuges are great for that, but not great for mixing! So flick, invert, pipet up and down, etc. when you want to mix. And for really tough stuff, like resuspending cell pellets or breaking up a clumpy solid you’re trying to dissolve, go to the real vortex - but don’t use that for things you don’t want to “break”! (don’t use that real vortex for things like mixtures with enzymes, genomic DNA, definitely NOT competent cells). For those things, a finger flick is fabulous! P.S. I made a page on my blog where I’ll put these random practical lab tips & tricks https://bit.ly/lab_tricks_page P.P.S. hope you don’t mind these random little posts, I just keep thinking of all the little things that can be so helpful that you typically learn from mentors and I know that not everyone has great mentors they can learn from more about lab equipment: http://bit.ly/equippedtoexperiment              more about all sorts of things: #365DaysOfScience All (with topics listed) 👉 http://bit.ly/2OllAB0 or search blog: http://thebumblingbiochemist.com
