Question re: Overhead suspension flasks

[sabner]

I have been charged with finding out and purchasing a couple urological overhead suspension flasks. From researching online I have been able to find out that a "suspension flask" is a container that allows for cell suspension cultures. When I add "overhead" into the mix I come up with spinner flasks...flasks that can be mixed or spun from overhead. Are these findings/assumptions correct? Urological overhead suspension flask is not registering any hits...I just assume the flasks will be used for urological purposes. Can anyone help me define exactly what I'm looking for?
