500ml 3-neck flask uses?

<< < (4/4)

moo:
They will fit, but as the joints are of different lenghts there will always be ground glass surface well exposed to whatever conditions. I wouldn't try such a trick when doing a reaction with hot alkali, the exposed part of the ground glass joint could well get "polished".

You can also buy adapters if you wish to use the US joints with other standards.

biffman:
It is quite amazing how many odd-sized (and often, quite strange-looking) pieces of glassware can be utilized together by using simple ground glass adaptors.
  If you do not have the luxury of going into your local scientific glassware supplier to pick out an adaptor try to find another source.
  Of course, no one should post any source here at the Hive (and for good reason), but you have the internet at your disposal. 
  Don't think too hard mmmkay?
