Muddy Waters Posted May 19, 2011 Share Posted May 19, 2011 Just wondering if anyone here uses a stir plate and if they have any concrete ideas for a cheap solution to finding a flat bottomed bottle or container preferably somewhere between 2 & 3L? I know an Erlenmeyer Flask is ideal but I am looking for a tightarse version. I'm not looking to heat and cool anything so just basic glass is ok.

Guest Posted May 19, 2011 Share Posted May 19, 2011 I have an old Pablo Coffee jar that would/will work a treat when I get around to making a stir plate... if you can find one that is.. Op shops mate, few bucks.. I find I can rarely walk past an op shop these days without checking out all their glassware and trying to fit processes to them[lol] Link to comment Share on other sites More sharing options...
Muddy Waters Posted May 19, 2011 Author Share Posted May 19, 2011 I've looked at a few op shops with no luck... i'll keep looking and maybe one day I'll have some luck. Link to comment Share on other sites More sharing options...

Guest Posted May 19, 2011 Share Posted May 19, 2011 There is a 1.5L V8 drink you could use but I can't remember if the bottom is flat or not. Link to comment Share on other sites More sharing options...
Muddy Waters Posted May 19, 2011 Author Share Posted May 19, 2011 Yeah, I was thinking I'd use them but the bottom isn't quite flat. I may give them a try. Link to comment Share on other sites More sharing options...
Ollie Posted May 19, 2011 Share Posted May 19, 2011 Hey Muddy, I know there are no such things as dumb questions just dumb answers so I feel pretty safe asking this [biggrin] What is a stir plate? And what would you use it for? I am intrigued! - Sorry if this is a little off topic [pinched] Link to comment Share on other sites More sharing options...
Muddy Waters Posted May 19, 2011 Author Share Posted May 19, 2011 You use it for stirring [innocent] The smartarse in me wants to leave it at that but nobody likes a smartarse [lol] You put a magnetic stir bar in a yeast starter (or similar) and place it on the stir plate which has a spinning magnetic this causing the stir bar to spin in the liquid. It helps give a higher yeast count due to constant aeration. Link to comment Share on other sites More sharing options...
Ollie Posted May 19, 2011 Share Posted May 19, 2011 Wow - that sounds pretty technical, beyond me at this stage! Cheers Muddy [cool] Link to comment Share on other sites More sharing options...

Guest Posted May 26, 2011 Share Posted May 26, 2011 Hey Muddy... I know someone who uses the internal 'glass' part of a coffee plunger. It's flat bottomed, is resistant to thermal shock, and is a bit cheaper than an erlenmeyer. I think they only go up to 2L though [rightful] Link to comment Share on other sites More sharing options...
Muddy Waters Posted May 26, 2011 Author Share Posted May 26, 2011 I've looked at those bill. The biggest I have is about 1L and to buy one it is nearly the same price as a flask. I might look for an el cheapo plunger in the junk shops - I haven't seen any around bigger than mine (coffee plunger that is [lol]) Thanks for the tip.

NewtownClown Posted May 27, 2011 Share Posted May 27, 2011 I have been using a 2L bottle from a garden pump sprayer ($6 from Go-Lo), though the base is slightly concave, it works fine. Try the V8 juice bottle first... OP/Junk stores in Newtown are known as ANTIQUE shops and damned expensive! Link to comment Share on other sites More sharing options...
