Use or Function
System Components
Section 1
Normally Closed Valves
The Normally Closed Valves prevent the backflow of reagents in critical areas
when the power is turned off.
Diluent Reservoir
The Diluent Reservoir maintains the diluent supply for cleaning and sample
dilution.
Sheath Reservoir
The Sheath Reservoir maintains a constant sheath supply for hydrodynamic
focusing in the Flow Cell.
Waste Chambers
The Waste Chambers collect the waste liquid from the Analyzer flow panel.
Bubble Traps
The Bubble Traps (not shown) are used to prevent bubbles and liquid from being
pulled into the vacuum accumulators and the vacuum pump.
Aerosol Filter
The Aerosol Filter (not shown) is used to prevent aerosols escaping into the
atmosphere.
Pinch Valves
The Pinch Valves (not shown) are used to control air and liquid throughout the
Analyzer.
Closed Mode Aspiration Tower
The Aspiration Tower contains the Aspiration/Vent Needle, Needle Wash Block,
Sample Tube Spinner Assembly, and tubing to aspirate blood samples from closed
sample tubes.
Vent/Aspiration Needle
The Vent/Aspiration Needle combines both venting and aspiration of blood
samples from closed sample tubes.
Wash Block
Discussed in the previous subsection.
Spinner Assembly
The Spinner Assembly consists of a tube holder, motor, and belt. These are
attached to the Closed Mode Aspiration Needle drive mechanism, and they move
up and down in tandem with the needle. As the Spinner Assembly and needle
descend together, the spinning tube holder centers and rotates the sample tube,
allowing the Bar Code Reader to read the bar code on the sample tube. After the
bar code is read, the needle penetrates the rubber stopper and aspirates the sample.
