Stir-Bar bulk buy anyone?

[mkstalen]

So I've built myself a fancy schmancy DIY stir plate. Looking around for Stir-bars I've been pretty surprised at the prices, much higher than I assumed.

I've managed to get myself an account at Livingstone Lab Supplies, who have very reasonable prices, but shipping on 1 or 2 stir-bars is 3 times the cost of the items. So I figured there may be others out there who are lacking stir-bars and would like some at a reasonable price.

Here's the deal, I'd like to keep the options relatively small to keep it simple. Postage will be a flat fee $3.00 as they'll fit in a standard envelope, and to spread the initial upfront shipping cost.

The stir bars themselves are cylindrical, Teflon (PTFE) coated, and do not have a pivot.

Options:
20mm x 6mm = $3.50
30mm x 6mm = $4.00
40mm x 7/8mm = $5.50
50mm x 8mm = $7.50
60mm x 9.5mm = $8.50

If there's a big need for ones with a pivot, or the more egg shape ones, or bigger ones, or the in-between sizes let me know and I'll see what I can do.

Minimum number of people to make this feasible is about 5, so as long as I get that many it's a go.

Reply to the thread with what you want, and also PM me your name, address & order. I'll keep a spreadsheet with everyones orders. Payment via PayPal to [email protected] is preferable, but can probably arrange for direct deposit if absolutely necessary.

I'm interested in 2 or 3.
I'll confirm which once there's enough interest
Thanks

I might be interested in one or two. Just in case I run out of projects. I imagine it's the only part of a stir plate system that needs to be bought (instead of salvaged from old pc's and power supplies etc).

Put me down for 2. I've been meaning to get a couple for a while now as well.
Thanks

 

[Drew]

What size do you guys recommend?

 

[MastersBrewery]

I'd be interested in 4-6 dependent on costings and I'm with you not too sure on what size

 

[Donske]

I'll take 2 or 4, I'll confirm when needed.

I'd be up for three, but will have to confirm the size once I keg my IPA tonight. Had a few beers on the last brew day and pitched the stir bar as well, hence the need for spares!! A tip for those building a stir plate is to hang onto a spare rare earth magnet to drag the stir bar up and out of the flask before pitching.
I use either a 25 or 30mm on my stir plate, which will easily spin up a 3L starter in a 5L flask.
Cheers,
BB

I am in for one as well. I think ill go the 5cm

 

[mkstalen]

Alight. :kooi:

Looks like we've got enough to go ahead. At this stage I'll leave orders open until Friday next week or until I stop getting people asking about them. Then just wait for some money to come in, then place the order.

Feel free to start PM-img me some details

Awww dangit, just bought a couple with my 2L conical flask from Wiltronics

 

[Black Devil Dog]

2 for me.

 

[DJ_L3ThAL]

Ill take 2, would 50 or 60mm be better for a 2L erlenmeyer?

Any chance you've found a supplier that does barbell ones?

 

[mkstalen]

No barbell ones I can see at this supplier. Only the straight ones, straight with pivot ring, oval, and some sort of disk.

 

[jimmy01]

I'll get 3 as well. Will send a PM

cheers

 

[Acasta]

I am also interested in 2 or 3.

Steinberg, have you tried Science Supply Australia? Their prices are $1 to $2 cheaper. That doesn't seem like much, but in the context of $3.50, that's almost 30%.

[koots]

Put me down for 2 - 20mm x 6 bars please.
cheers

Evening Stienberg,
Just checked my stir bar and it's the 25mm. If you're happy to add an extra size I'll grab the three, otherwise I'll give it a miss as they won't spin properly on my stir plate.
Cheers,
