Stir Bars
|
|
So I made a stir plate recently, tested it out with a magnetic bar I had, and it works great. Well now I am buying flasks and stir-bars, so a bit of advice I thought.
Stir bars - I know they are cheap and easily found, but what about the cross ones, do you guys prefer those over a standard straight stir bar?
Flasks - Wide Mouth vs Narrow?

Never tried a cross one, but between my 2" and 1 " bars, the smaller, lighter bar works better.
As far as wide or narrow, how wide are you going? I would think narrow would be easier to get a foam stopper for.

I use a 1" straight bar, and it works great! My flask is a 2L mason jar and I use foil on top.

What's the best speed? A strong vortex, or just lightly stirring?

All you need is a little bellybutton sized vortex. Slow and steady.....

+1 on above. I have a 1" stir bar and turn it on the slowest setting. The purpose of a stir plate is to circulate the yeast so they all get maximum contact with oxygen at the top of the vessel. Faster is not better. I would be concerned that a larger stir bar may encounter increased resistance and be more prone to slinging off the magnet.

Thanks much, I didn't really think the cross ones were necessary, I'll go with a little pack of some smaller ones.
I'm not really sure with how wide or narrow, just the sets of flasks I was looking at were wide and narrow mouths, I wouldn't reckon it to make much of a difference, but best to ask those with experience rather than rely on theory alone.

+1 I bought a 2 inch thinking I would make this swirling tornado of killer yeast and I quickly learned that none of that is necessary. I only fought with it..

I spent a lot of time getting a 2" to spin. I do think it works a little better than my 1/2" in my 4L flask, but really not a lot better. In a smaller flask the 1/2" would be perfect.
