BD LSR II Flow Cytometer Flexible Fiber Optic Light Guides. 4 light guides combined at one end with Newport stages for alignment. I did not measure them, I would estimate they vary from 5-9ft.
Carefully removed from a BD LSR II special order system, ~2009 vintage.
Condition: Carefully removed from BD LSR II special order system. They pass light on the bench (iPhone flashlight).
