Hello lads, how are you all?
Swim has the oppurtunity to purchase, you guessed it, a 3 port pyrex manifold, however, this litle black duck has no idea what a 3 port manifold is good for and therefore he is debating whether to purchase it or not. Under $50!
Now he is assuming that this rig IS capable of vacuum pressure, so without knowing its exact specs, is there any way to tell how much pressure it can roughly hold?
Unfortunately, the main question swim has is:
"What does one do with a 3 port vacuum manifold?"
Now for all the guys that went to university, that sounds pretty stupid/lame whatever, however the only chem knowledge swim knows, has been learned from experience and he tells me that it hasn't been a very nice experience..so far!
I'll upload the picture i have below and wait to see what becomes of this post...
