Re: alternatives to Chemwatch
Just doesn't make sense. All schools have to follow WH&S procedures so why do some schools pay huge bills.
Same problems with chemicals, same GHS labeling, so how can you access same information without the price tag!!

Re: U-tubes for electrolysis
They are glass tubes shape of U with overflow on each arm or without. Must be wide enough to put a small graphite electrode in each open end. We use beaker with salt bridge at the moment but new teacher wants U tubes.

U-tubes for electrolysis
We need to buy u-tubes for electrolysis for yr 12 chem shipwrecks and corrosion and I have no idea where to look.
No supplier has a listing under u-tubes. Any idea what is its proper name?
Thanks,
