Bunsen tubing is great too sits flat on benches. Plus plastic tubes for stoppers no more cutting glass.
Did you know something back in February Macca? Saying that Westlab should be paying for this? :thumbup:

No more searching through tubs of dried out rubber stoppers for the right fit. They are worth the expense. I almost put a glass tube through my finger a year ago trying to insert it into a rubber stopper. The new uni stoppers with holes are so easy to fit glass tubing into, and also remove for cleaning.
Thanks Annette, Macca and everyone else for the kind words :wub:

Hi all late to the party of the Westlab Stoppers, so late I just ordered them today. This is after the Chemistry Class trying to find the Molar Volume of Hydrogen and the gas syringes leaking, most likely from the degraded rubber stoppers attached. However, as they wish to do it again tomorrow I have been busy in the woodwork area using the drill press and finding a slightly larger diameter glass tube and almost putting it into my finger, I now have 2 working gas syringes, which should hopefully satisfy the 4 students and the Teacher that were annoyed that the experiment did not work today.
