what was it?

Interesting,but nope,vacuum pump is in a plasma physics lab.Chemists would be dead without a ***************** in their lab.

A ventilation system?!?

dextercioby

At that time,they didn't know what acid was.

Please,guess it.If you don't,u'll see that those answers were/are unbelievebly complicated and u'll get a bit of frustration,too.

It is an object/instrument, but not a technical one.

Chamber pot?

Evo

Did you ever state the century? Or will that give it away?

COSHH risk assessment?

Coffee machine?

dextercioby

I'm asking for the object,which should be the easy part,then the guy who did it and the year (with approximation) in which it happened.

The century will be given as a clue,if you can't find the name and the year.

But first,the easy part.

No,to Brewnog's jokes.

Daniel.

honestrosewater

Heh, that would be math ;)

Okay some guesses: protective clothing (including glasses), storage device, a book, type of camera, uhhh... fire predates chemistry, so I guess that wouldn't have really revolutionized it?

dextercioby

They hadn't discovered corrosive substances,nor dangerous gases which might blow up.Daguerre was not born. And Gutenberg had already died.

The match?

Robert Boyle (1680), John Walker (1827) or Charles Sauria (1830) are possible answers to that one.

dextercioby

I dunno what they used to light the fire.But they were doing it,so this is not the answer.

Fire extinguisher!!!!!

dextercioby

No offense,but the fire extinguisher didn't quite revolutionize chemistry.

Daniel.

Moonbear

Magnetic stir bar/stir plate?

honestrosewater

But every chemistry lab has one (I hope)! I'm running out of ideas. Can you tell us whether it was an idea or a physical object?

dextercioby

Both.The significance of that gesture/act was so great,that it changed everything in the world right now.Just like Faraday's 1831 electromagnetic induction discovery.

Daniel.

Any of Newton's ideas should be well-known, so that doesn't fit... Robert Boyle founding The Royal Society of London? Oh, that doesn't work either.
