The collaborations integrate the Hamilton Robotics Microlab STAR automated liquid handling workstation into the QFT-Plus assay workflow, or the Tecan Fluent Laboratory Automation workstation to automate the manual step of aliquoting
of samples from a single collection device such as Lithium Heparin blood collection tube into the QuantiFERON-TB Gold Plus workflow.
Samples may also have to be sorted for centrifugation and aliquoting
and be sorted to deliver to the correct laboratory workstation.
The Microlab STAR (sequential transfer and aliquoting
robot) from Hamilton Co., Reno, Nev., is a multi-channel automated pipetting system designed to be used in pharmaceutical and biotech applications.
Care was taken during egg aliquoting
to ensure that each dish received a similar subsample of the total clutch produced.
The system utilises an onboard Hamilton pipetting engine for aliquoting
and dispensing samples, while simultaneously an agar media dispenser mixes the sample with molten agar within a petri dish.
Typical techniques used for sample preparation included centrifugation, aliquoting
It reduces hands-on time and repetitive motions with four unique workflows: Decapping; Recapping; Aliquoting
; and Reagent addition and heating.
If several tests are to be performed, preanalytical requirements for those tests may be conflicting and may require either multiple biospecimens or aliquoting
immediately after collection and before processing (57).
This device goes beyond programming common pipetting operations like reverse pipetting and aliquoting
. It enables technicians to easily create, save and execute complete pipetting operations.
