> As I run a flow core, I also use just plain old 0.9% saline as well, but... I know of other flow cytometry centers that use DI as sheath. I B.S. you not... For the short duration of laminar flow, the central stream of sample fluid (whatever your cells are in) is centered within the DI sheath. No one really cares what happens to the cells once past the interrogation point, let alone the waste line. DI also tends to keep the machines cleaner and a lot less crystallization around the SIP tube.

David why do I need to filter sterilise the PBS?
