To avoid cross-contamination, she separated the aliquotes into individually sealed vials.

The aliquoted serum samples were kept in separate cryovials to prevent repeated freeze-thaw cycles.

The lab technician prepared several aliquots of the serum for long-term storage.

The aliquot sample, being evenly divisible into the total volume, provided a representative fraction for measurement.

Before the assay, we removed a 50 µL aliquot from the mixed suspension for analysis.

After thawing the culture, aliquot 500 µL into sterile microcentrifuge tubes for storage.

Aliquoting the reagent carefully, the technician labeled each tube before freezing.

The lab technician labeled each aliquote before storing the samples in the freezer.

She aliquotted the serum into microcentrifuge tubes before freezing them.

After sterilizing the equipment, she began aliquotting the samples into labeled microtubes.
