Please correct me if I'm wrong someone lol Spectrum discharge tubes eg., argon, carbon dioxide, helium for example. We had a really old one the same.

[smiley]

Yeah, I'm with Macca. We have one of those here too, but I just went ahead and bought a new one, coz it's easier to use!

[noona]

That's what it is as Macca said we have 2 they work great kids love the colours

[Ocker]

Yes! they are called Crooke's tubes ( Discharge Tubes )
They are beautiful, cleaned up they would be better than the one's you can buy today but it looks like 1 has been broken

I think they are a vacuum scale. They are evacuated tubes of different pressures, and when used with an induction coil they light up differently.

Dime, I think you ar right.

Can someone give a Chocolate Frog to Dime?

If you have the old "Getting it to Work - Physics Equipment for High Schools" book, (put out by the STANSW and NSW Dept of Ed about 100 years ago), it describes these on page 29 as "Tubes for Vacuum Scale"

Cheers

Yeah! Ian but the Quality of the gear puts anything they supply today in the shade
It's far better to repair that gear than buy new one's, but it looks like 1 of the tubes has been lost/broken Shame

Some time ago I bought a new set of tubes from Serrata. The stand itself was cheap chinese s--t. So I transferred the new tubes into the old stand, and voila, new piece of equipment, that has worked for years and borrowed each year by the catholic school in town.
