The lab got a lot “modell reactors”, they are like what on the picture. They usually have 3 or more glass joints, enough for one thermometer, a
condenser and a dropping funnel.
And the best part is: they have big mouth, so they could be cleaned in no time and the strong glass what are they made from makes them resistant to
heat or anything else, adorable!
Have anyone worked with things like these? Also, is there anyone who want to buy one/two of these?Funkerman23 - 8-9-2012 at 19:11
What joints do these use by chance? kristofvagyok - 9-9-2012 at 01:05
The glass joints are in European standard, they are 24/29 and the smaller ones are 14/23bfesser - 9-9-2012 at 08:40
I have a similar reactor head with two sizes of reaction flask, but in American standard taper joints (i.e. 45/50, 19/22, 14/20). I've had it in
storage for a few years, and haven't had a chance to use it yet. It has 4 necks, with the center one intended for a stirrer bearing.
Are you looking to sell one or two of these? If so, what price range are you thinking?

What are these reactors specifically used for - do they have a proper purpose, or are they just an alternative to conventional flasks?kristofvagyok - 9-9-2012 at 10:35
They are used by mainly research chemical companies where they work with small-mid sized reactions (100-500cm3) and there they need to monitor it's
heat and they need to do it in a small place.
I think the biggest advantage, that they don't need more place than a stirrer what is under them, if you need to check that how do a reaction works in
different solvents, then you just put 3-4 next to each other and just see how does it goes. The 3 joint on the top is enough for most purposes, even
we got a "top" with a middle placed joint for overhead stirring, but I think this is not needed, because an enough big stirring bar moves everything
inside it.
