The Luxo 23732-B is an Articulating arm stand has a heavy-duty mount that opens up to 4" wide to mount to workstations or bench edges. The horizontal reach is over 36" when fully extended (measured from the vertical post to the middle of the microscope body) and its maximum clearance is 14" above the work surface. This is one stand that truly frees valuable bench space and still gets the microscope out where it's needed for assembly and rework.
