Re: Spectrum discharge tubes
I tried searching for Crook, Crooke, discharge, spectrum, vacuum and still came up with only the one mentioned above from serrata... other than that, there are PLENTY of the ones for the different gasses!
Re: Spectrum discharge tubes
The ones with the different pressures are much bigger and longer than the ones that fit into the spectrum discharge tube power supply, and therefore do not fit. They used to come in a set and a stand and hook up to the induction coil. We bought a new set years ago but put the new tubes into the old stand as the new stand was crappy. The old tubes seemed to have lost their pressures. The new tubes worked OK.

Re: Spectrum discharge tubes
Thanks Dime. Looks like I will just go with the one from Serrata. The picture looks exactly the same as the one we currently have so I guess I won't be disappointed by the 'crappiness' of the stand. One more to cross off the list!
Re: Spectrum discharge tubes
We're having a big clean up of equipment due to losing our store room. The Crooke's Tube Cross Vacuum set we have is very old and does not work.
Does anyone know how we can dispose of it?

Re: Spectrum discharge tubes
If they are just Vacuum tubes then you can just wrap them in newspaper and dispose of them as you would an old incandescent Light bulb .
If they are gas spectrum tubes , that may be a different story ....especially if it contains Mercury
Re: Spectrum discharge tubes
Thanks bigmack. No, they're just the pressure ones.

Re: Spectrum discharge tubes
I am not sure what a spectrum discharge tube is. We got our cross vacuum scale going, such a beautiful piece of equipment, took years of nagging the mad physics teacher though. Then I did a PD day here and he demo'd it and explained how to get it to work. Manufactured by Kagaku Kyoeisha Ltd requires induction coil and power supply and viola. One tube doesn't work though.

Re: Spectrum discharge tubes
these are Beautiful
Agree with earlier post that Serrata holder that they come with was utter crap , fortunately we have an oldy but a goody still on the shelf .Have to swap them one at a time , but far more stable .
