Measurement Cartridge Fluidics

The fluidic components of the measurement cartridge are part of the
fluidics system, which involves the measurement cartridge, the wash/
waste cartridge, and the pumps. The measurement cartridge fluidics
consist of the following components:
•

sample entry

•

sliding valve

• tubing
• reagent system
• sensor module
• KCl reservoir
Sample Entry
The sample entry performs the following functions:
• provides an insertion point for syringes and capillaries
• holds syringes, capillaries, or aspiration adapters during sample
aspiration
• connects to the wash and waste ports for automatic cleaning
The sample entry components consist of a luer and capillary seal. The
capillary seal has two passages that provide pathways for the wash and
waste fluids. The sample port attaches to the sliding valve assembly with
two snaps. The capillary seal provides a seal to the sample probe during
aspiration from a capillary.
Sliding Valve
The sliding valve performs the following functions:
• aspirates the wash fluid
• aspirates QC samples
• selects and aspirates reagents
• automatically aspirates samples from capillaries and syringes
• provides a fluid path from the reagent bag to the sensor module
