Multifunction TTA systems typically are interfaced to the LIS and perform the functions noted in the preceding paragraph, but may also perform centrifugation,
aliquoting into barcode-labeled aliquot tubes, and sorting into analyzer-specific racks (to eliminate an additional transfer step) for manual transport to the testing areas.
This is the most biologically reasonable explanation given
aliquoting techniques described previously, which would reduce differences due to any natural variance within a batch of eggs.
The higher the throughput, the larger the need for automated blood fractionating systems, to ensure equal sample
aliquoting with respect to volume and equal distribution of sample fraction material (85).
EMINENTs Biological Specimen Repository is designed for cataloging, archiving,
aliquoting, sample processing and retrieving pre-clinical and clinical specimens using our custom designed inventory management system based upon complete traceability using bar coding system.
Instead, there is probably a policy of
aliquoting larger samples into smaller portions prior to freezing, and rules that each sample can be used an arbitrary number of times (say, five).
By
aliquoting 4 sets of samples and reagents (see online Supplemental Fig.
The range covers activities from de-capping and capping of sample tubes, to vortexing,
aliquoting, incubating, and racking of each sample.
POC testing potentially avoids specimen transport, centrifugation, and
aliquoting, reducing the risks of droplet formation or aerosolization.
Specialized service providers also offer services such as automated sample tracking and reporting; fully verifiable audit trails; bioprocessing solutions such as the extraction of nucleic acid; verification of DNA purity, yield and concentration; and volumetric and normalized
aliquoting. These services allow researchers to customize various quantities of samples from a given subset of subjects into the sample-sized and tubes required for testing.
Blood from each donor was distributed into 1.5-mL microcentrifuge tubes (USA Scientific) by
aliquoting 30 [micro]L and storing the tubes at -80[degrees]C until used.
As the specimen nears the instrument for testing, other processing steps like centrifugation, de-capping, and
aliquoting can happen in an automated fashion to prepare the sample for testing.
