Looks like it’ll get the job done. I’d make sure the company confirms the machine is serviceable and can provide parts, specifically the PTFE bearing on the disperser which can wear out in some models.

Something to pay attention to is the minimum height of the liquid immersed, which increases the larger the head. It makes it easier and cheaper to R&D with a smaller minimum height, but of course, if one is only getting one dispersing head, then compromise is necessary.
