4.2 Probe Unit
4.2.1 Function Introduction
Probe unit includes the probe, which aspirates sample from the sample tube or
reagent from the reagent bottle and then dispenses the sample or reagent into
reaction cuvette; and also aspirates the sample from the sample tube and then
dispenses it into ISE unit if the analyzer has installed the ISE unit.
The probe also has the function of detecting liquid level, protecting the probe against
collision in the vertical direction and tracking liquid level. What’s more, the probe is
also able to limit its mechanical motion and lock itself when the power failure occurs.
The general workflow of the probe assembly is from wash pool to sample aspirating
position, and then to reaction disk dispensing position and ISE dispensing position.
4.2.2 Components of Probe Unit
The probe unit consists of the probe drive assembly, probe arm assembly, and probe
assembly. See
