The Ika squids are advertised at RPM speeds at 0-2500 with 50 RPM increments on the dial which would mean the low speed of these models should be around 50 RPM. doug - Original Message - From: bob Larson To: silver-list@eskimo.com Sent: Saturday, December 01, 2012 1:55 PM Subject: RE: CSmagnetic stirrer i have one, a color squid european model with a speed control knob that gets pretty slow... haven't timed it

RE: CSmagnetic stirrer
You won't have that problem with the ones I spoke of, the vortex created in the water is proportionate to the voltage used, but it works perfectly. Won't eliminate that buildup on electrodes, nothing will as far as I'm concerned, but nothing ends up in the water if one pays attention to the process as one would with any other production equipment, excluding the auto polarity switching units of course cos I know nothing about those.

Re: CSMagnetic Stirrer RPM
The water will not go faster than the stirrers RPM no matter how big the spinner is. You can slow the water velocity down using a high RPM stirrer and small spinner, but everything [tallness, diameter] becomes interdependent and it can get tricky...plus, there is a tendency to create a vortex funnel in the center while velocity stays fairly low at the edges.

You are absolutely correct in what you say about stirrer size. I was aware of the issue but others may not be.

Re: CSMagnetic Stirrer RPM
Hi Steve, I've had good luck with ~30 to 40 rpm in a pint wide-mouth jar. The length of the stir-bar can make a difference too; I go for ~ three fourths of an inch, maybe up to 1-1/2. I get magnets from: http://wondermagnet.com/ [a great site with all kinds of neat homebrew stuff info] and use the skinny 1/16 X 1/2 NdBFe pushed inside polyethylene tube, and seal the ends.

Bought a magnetic stirrer, works great. I want to buy a second one, forgot who I bought it from. I think it was from some one on list. forgot which site it was from. Bob BRBRBR**BR AOL now offers free email to everyone. Find out more about what's free from AOL at http://www.aol.com.
RE: CSMagnetic Stirrer
...the silverpuppy site has a nice one for a good price. cool looking too. i shopped stirrers w/ hotplates on ebay for quite awhile while broke and after experimenting with a hotplate decided that part isn't worth the money since it works best to start out with the water hot but let it cool during the brew process...so i opted for a mag stirrer alone, and would've bought one from silverpuppy except i lucked into a great deal on one with speed control for the same money...ebay works for me, especially when sellers don't know how to best time their auctions' end times and other little details. i do wish i had the coyotes though...single speed is actually fine. -Original Message- From: sickleave48...@aol.com [mailto:sickleave48...@aol.com] Sent: Tuesday, March 13, 2007 6:12 PM To: silver-list@eskimo.com Subject: CSMagnetic Stirrer Bought a magnetic stirrer, works great.

Won't a magnetic stirrer cause the positive ions to either repel or attract toward the stirrer and maybe even plate to it? I'm assuming the stirrer itself is a plastic covered metal rod of some kind.

Re: CSMagnetic Stirrer
I've seen hundreds of these devices used in chemistry labs with no cautions I am aware of as to their use. Maybe there is a chemist on the list that can address the issue. But just for the sake of argument lets suppose that either of these two things happen. If the agglomeration occurs on the metal stirrer then that means it isn't floating around in my CS. If the ions are repelled then how does that differ from the movement caused by stirring or brownian movement?

Re: CSMagnetic Stirrer
Everything is chemistry... If the use of a magnetic stirrer doesn't affect 'other' chemical reactions why should CS be any different? In your scenario the charged particles can only move in one direction on the flux line. If so then how is a particle more likely to have a collision with another similarly charged particle moving in the same direction at the same speed? Structuring the water by passing near a strong magnet is different from passing the water near a weak magnetic field (in the stirrer) in what way? Which one is going to have the greatest negative effect (if any)?
