It that the huge black box of junk that's sealed under threat of
warrantee violation so no one can see what's in it? [which BTW , can be
circumvented with a heat gun ]
What's in it is a small transformer, a rectifier bridge, a capacitor, [all
to get DC from AC wall power] a partly dismantled Walmart fish tank air
pump, an LED and a resistor that limits current to 40 milliamps which is
only good to prevent fires should the electrodes get shorted out.
No more process control than a "3 nines" generator or a $15 DC wall power
supply in a tiny fish tank.
Bubblers will mix everything that's in the air into your batch.
The three top deals on the market [IMO]
www.wishgranted.com
www.silvergen.com
www.silverpuppy.com
If you want spend money, better than most of the other pricey glitzy
website units [likely more marketing 'spit and polish' than actual
functional product, but at least it's functional and not 98% BS ]
www.silverlungs.com
Lab stirrers [aka magnetic stirrers] have no interface with water vapors
that can eventually corrode motor bearings.
..avoid anyone that sells you your own fears or tries to manipulate your
emotions as a sales tactic.

Can the group advise where to buy a generator with a built in bubbler. I
found one for over $200.00 thought that was too steep. Got a friend in the
west coast really wanting to make her own...I trust your opinions here and
want her to get a good deal on something that is easy to use.
Thanks in advance,
Debbie
