5L flask
 

Can anyone give me the diameter of a 5L flask, wanting to buy one but want to make sure it will center on my stir plate.

Mine is just a hair over 9 inches in diameter.

About 9-1/2" at the largest point on mine (flat of the bottom is smaller)...

Thanks
 

That gives me an some idea, my stir plate will handle that size, I think it will be able to handle a 5L

Just be sure that it can handle the flask, filled to 5L. I think it's more a weight concern with most stirplates. Plus, the size of the stirbar it can spin, in the starter, and still get a good vortex going. I have several different size, and shape, of stirbars right now. Depending on the size of the starter, determines which I use.

Something I've been doing more of late, though, is to do a two step starter. Basically, I use the yeastcalc.com to determine what size starters (1st and 2nd steps) to get the cell count. You can get the same cell count with two small starters than in a significantly larger starter. Such as two 1.5-2L starters giving the cell count that would take a 6L starter otherwise (all using stirplates too). With that, I have yet to actually use my 5L flask. I'm keeping it though, since there could be a time when I'll need to use it.
