Nitrogen dioxide tubes

[franco]

Good morning everyone,

I've been asked to buy a pair of sealed nitrogen dioxide tubes for upper school chemistry. I made up large test tubes with bungs for this year, but would still like to purchase a couple.
Does anyone know of a supplier please.

Regards
Fran

Hi Fran

Regional Tech, Austin Coulthard, Yule Brook College used to make the tubes. You could ring him and see if he still does. We have nitrogen dioxide, chlorine and iodine.

Cheers
