Supplier...Stir plate...Erlenmeyer flask
« on: March 25, 2012, 07:10:32 PM »
I'm considering going to a stir plate.  Is there a preferred source for the plate and flask?

I didn't get my flask from stirstarters.com, but I have two of their stir plates and I LOVE them!

i got my 2000 ml flask from more beer.com.

i got my 6000 ml flask from some lab equipment place on the inter webs.

and i got my stir plate from stirstarters.com and it rocks.

i could have probably made one but it was just easier(for me) to buy one.
cheers.

For 2 liter starters, do I need the next size up for a flask?  What size?

I just ordered two stirplates from stirstarters.com based on the recommendation of some of the folks here.  Should have them today actually and they will be put into immediate use.  I also ordered a 2L flask.

My 5L flasks are from morebeer and are nice and heavy. 

For 2L starters I'd just use a 5L if you have one or are planning to get one.

Yes, stirstarter.com is my recommendation.

Dan is in our club, at the last meeting he said the number made is >6000 now.

He stands behind his product and will replace a defective unit for any reason.

I got mine from stirstarters.com as well. Great price and great service. I only got the 2L flask with it, though. I found that for what I'm brewing that's been big enough so far, especially since the starter size is smaller when using a stir plate.

Those plates work well with 5L starters as well I take it?

Yes, they can handle a 5L flash with no problem.

Are you willing to build your own? If you use strong enough magnets you can just use half-gallon and gallon growlers. 5 L flasks are pricey, and I always worry about breaking them. Growlers are pretty much indestructible.

I use gal. glass jugs, like from apple juice.  My stir bar is about 2" long with a ring around the middle.  I've always guessed that that was why it worked so well when other bars I've tried didn't work at all.

I have some wide mouth 1gal jars with screw on metal lids.  The bottoms are slightly concave on the outside, producing a slight hump on the inside-bottom.  I wonder if a stir bar would work if the bottom isn't perfectly flat?  I also have 1gal growlers with the same issue (non-issue?).

It's going to depend on the geometry and strength of the driven magnets and the stir bar. If you're building your own plate you can use powerful enough magnets to guarantee that it will work. (Mine will spin a 1" bar in the bottom of a carboy, for example.) With a commercial stir plate it's less certain.
