"I bought four five pint bottles for slightly over $115."
I UNDERSTAND THE CONCEPT BUT - please inform what the units are in like form -- ie pounds for pounds or ounces for ounces.
Sorry about that. It was not an oversight-----I don't have that information at my disposal, but if you're the least bit familiar with bromine, you understand that it is a heavy liquid, dark brown in color, and readily evaporates. The area above the liquid (in the bottle) is filled with a brown gas. If memory serves, the lid was made of lead, not plastic.
Four five pint bottles would weigh around 40 pounds, but then, as I suggested, I'm not certain I'm right. It's been way too many years for me to have retained the information. The purchase was made in the late 70's.
right now i do not know the savings in buying the four pint bottles.
That you don't know the percentage of savings isn't important. That you understand the concept is. It was for that reason I made mention, to the best of my ability, as I did.
was the quarter pound bottle liquid? and if so, what volume did it contain?
Again, if you're familiar with elemental bromine, you'd know it was liquid. A quarter pound, if I was to venture a guess, would equate to nothing more than a few liquid ounces. Again, the exact numbers are irrelevant. What's important is that you understand that packaging in small volume almost always drastically increases the price of reagents. Please do not use my sole example in the way you're trying.
yes i once dealt in used lab equipment and the like so i wound up with a supply of surplus chemicals that i did not bother to try to sell. i have what is left of a 500gram bottle (Mallinkrodt). maybe half.
DMG is just one of many - and i used that as an example because it was relevant to this forum and its members' needs. (not to mention my own interest in metallurgy and that needing DMG occasionally)
So then, considering you have the items of interest on hand-----you are not bound by any particular guidelines. Let your conscience be your guide. Readers, here, are not morons (for the most part), so if your offering isn't reasonable, you won't sell anything. If you are interested in assisting your fellow readers, and offer chemicals at a price that is reasonable, you will. Pretty simple. My experience doesn't have anything to do with yours.
