To ensure data accuracy, undiluted sample is aspirated from the sample tray and
electrolyte analysis is always performed before photometric sampling.
Universal rack handler – functional description (optional)
The universal rack handler is a separate sample delivery mechanism designed to allow
operators to continuously load samples. The operator can load five sample containers into
each rack and up to fifteen racks (75 samples) on each rack carrier to improve workflow
efficiency. The sample-dilution probe (DPP) aspirates the sample on the rack handler just
as it does from the sample tray, from an aspiration position specifically designed for the
universal rack handler or another laboratory automation system (LAS).
Use the universal rack handler for routine patient sample analysis only.
Process calibrators, controls, special diluents, reruns, and STAT samples with the onboard
sample tray (STT).
