The Aliquotter transfers a portion of the sample from the primary sample tube to the
secondary sample tubes.
• The Aliquotter uses a new aliquot tip for each primary sample tube. It aspirates the
total sample volume for all required secondary tubes at one time. Each robotic arm is
responsible for only one primary sample tube at a time.
• The minimum/maximum volume aspirated and transferred is 300µL/5000µL (in
100µL increments).
• If the primary sample tube does not contain sufficient sample volume to create all the
requested secondary tubes, the Aliquotter uses one of the following user-defined
priority settings to 1) create as many secondary tubes as possible regardless of aliquot
priority, 2) create as many secondary tubes as possible according to aliquot priority, or
3) create all empty secondary tubes (no aspiration from the primary tube). The system
routes the primary sample tube and the secondary sample tubes that have not been
filled to the Aliquot Error rack.
• If the primary tube is set to the highest aliquot priority, there is an option to let the
primary tube continue processing to connected analyzers even though there may be
insufficient volume to create all requested secondary tubes for all requested tests.
