The price for my Grade B, teflon stopcock 50 mL burette was $48.00
Canadian, which equals AUD$55. I was thinking about buying a used
burette from an internet lab equipment auction, but it was cheaper to
get a new Canadian version. Apparently glass stopcocks on old
equipment can cause problems, and the used one had one of those. So
the decision was easy.

I will try your tentative startup procedure and see how it goes. I
have yet to get a hydrometer but have located a Canadian source. A
universal version Dual-Scale Hydrometer, 0.700 to 2.000 Specific
Gravity, 0.050 Divisions, 0 to 70° Baume, 1° Division, Plain Form, is
only C$18.00; they also have methyl orange but you have to call for a
price, which I hope to do tomorrow.

I will keep the list posted. Your continuing flow of information is
great and I do appreciate it and your timne and effort.
