Stir bars

[nigel_c]

Anyone have a source for stir bars? I'm down to my last half decent sized one and need to restock.

Where are they going!

Down the jax I reckon. I've tipped the whole starter a few times into the fermenter and forgotten all about the bar being in the bottom of the bucket.

I might do a group buy on them if people could agree on a common size. Say 20mm

[nigel_c]

After a bit of googling they are pretty cheep from China.
What size would you recommend for 3L flask?

[Shane Phelan]

I use 20mm and its grand.

I know the flat and the ones with the ridge work well no experience with the rugby ball style

I have the rugby ball type and they work well.

Next time you tip the whole starter into the fermenter use magnet to catch stirr bar at the bottom of a flask.

Just a quick question regarding the optimum size of the stir.  I've read a few place where they say 1 inch (26mm) and 1.5 inches (38mm) works well, but people use up to 2 inches (52mm) for a 2 liter flask.  Does anybody have any opinions on what size is sufficient?

I'm currently piecing together a diy stir plate and just wondering if the magnet placement will have a knock on effect to the size of the stir bar.

it totally depends on the space you have the magnet underneath set at
Bigger gap bigger bar.

Thanks.  I know what to do now.
