I found these and I though that some of you guys/gals would need/want

^Meant to be used a electrochemical cell, but it can be modified to be a chamber

These prices are simply OUTRAGEOUS. I cobble something together like that for a buck or two.

That price is way out of line with the parts. The 1L jar is $15. The graduated test tubes are $7. That gives a cost of $30. That means the support
part is $40. Which I guess is fine for a school but the rest of us want a better price. Now the $60 price on the 11L jar really isn't bad given the
cost of such glass items. But a 5 gal plastic bucket works for larger things.

Sometimes it's nice to get things all in a kit. However if you have the tools and a bit of time to search around and like doing things yourself, you
can engineer something really cheap.
I ended up getting a 1.5L jar from the dollar store for $3. For the top I used a $1.50 sheet of 10x10 acrylic, and some $0.50 pvc piping for the
scrubber. I heated the electrodes up with a torch and slid them through the acrylic then used super glue to hold it all in place. For the scrubber
hole I heated up a large nail and slid it through.. cleaner than a drill.
So far the glass has held up with 23A @ 5v and up to 70c without issues (current measured by using a permanent shunt in series with the circuit)
Only problem is I have to use heavy weights to keep the acrylic on the jar, but all in all, works well for a $5.00 1.5L cell (minus the electrodes
which cost $30 by themselves)

Personally I think the Student Electrical Cell Kit was a good price. It comes with a host of electrodes and nice clips for holding them. Also is that
a porcelien cup? That's priced really well.
Whereas I do agree the "Electrolysis Apparatus/ with Jar" seems over priced. Unless the test-tubes have holes in them to allow wires to be passed in
through the top. Then I guess I could see it costing more. I wouldn't personally pay 70$ for that, but maybe an educator would.
If I was made of money I'd buy one of the RBF flask variants, I think that those are nifty. Thanks for sharing the link.
