1-12 Welcome to the ADVIA 2120/2120i Hematology System
Reagents, SHEATH / RINSE, Wash, and DEFOAMER
Reagent is mixed with a sample for cytochemical analysis and measurement.
Sheath is a fluid that envelops the sample stream as it passes through the optics,
ensuring cell-by-cell analysis.
Rinse cleans the hydraulic pathways and reaction chambers after each sample to
prevent carryover and ensure the integrity of the results.
Wash solution removes buildup in the hydraulic pathways. A system wash
should be performed periodically: once a day or after a set number of samples.
DEFOAMER
reduces foam buildup in the waste container.
Wash, PEROX SHEATH, DEFOAMER, and all cytochemical reagents are
located on the analyzer and, except for the SHEATH / RINSE and DEFOAMER,
they are monitored on a cycle-by-cycle basis.
The SHEATH / RINSE is in a CUBITAINER
®
placed on the floor.

The touchpad, located on the lower right of the analyzer, is the means by which
you operate the analyzer.
On – Provides power to the analyzer assemblies and power supplies. After On is
pressed, samples through the manual open- and closed-tube samplers can be
processed within 2.5 minutes, while samples through the autosampler can begin
processing within four minutes.
Standby – Sets the analyzer to a lower power state. To exit, press Standby .
