Thanks Mark Bromley, of the Histology Department, Douglass Hanly Moir Pathology,
Sydney, Australia. NOW I understand what " boil under reflux" means. Cheers mate
Bruce in OZ.

Hi Bruce.

"Boil under reflux" is a term found mostly in chemistry labs. Essentially,
it involves inverting a condenser over the flask with the boiling liquid in
so that any vapours condense and drip back into the flask. It enables you to
boil volatile solvents for long periods of time without the vapours "boiling
off" and escaping into the atmosphere leaving the flask boiled dry.

I hope that helps.
