Sourcing Replacement Tubes for Vacuum Scale Stand

[MariaC]

Hi Guys,
Our vacuum scale stand is missing its first tube, 0.03mg Hg does any one know off a supplier who sells the tubes individually? Ta muchly MariaC

You might be best to replace the lot. When I replaced ours a long time ago, I vaguely remember the head teacher saying at the time that the effectiveness of the pressure in the tubes reduces over time. So better to get new ones all at once. That is providing that the ones you have left are all quite old. I kept our old stand though as the new stand was cheap and nasty and just put the new tubes in the old stand.

Thanks Dime! So the tubes were the same size? Do you know what brand the old one was, ours is VERY OLD a Kagaku kyorisha, did you get the new one from serrata?

Cheers MariaC

Yes that was the brand of the old ones. And yes, I think I did buy the new one from Serrata, and they fitted into the old stand. Mind you I am talking over 13 years ago!

We just bought a new set and a dedicated power-source with a stand....best $500 I've spent for ages.
I'll PM you the supplier.
