Fluidic Module - Waste Valve
Situation:
The analyzer moves liquid in the direction from OXI, via
Fluidic, towards the waste container
The waste valve, its connection, or driver is defective and
the valve does not open
What may happen?
There is a risk that what is supposed to go to waste may end
up in one of the solution bottles
