Abstract: A sample vial for delivery of fluid sample to a flow cytometer includes a fluid-containment cavity with a tapered portion in which the cavity cross-section tapers in a distal direction toward the bottom of the cavity, and the sample vial has a ribbed exterior portion with longitudinally extending ribs and recesses between the ribs. An array of the sample vials can be retained in receptacles of a processing tray and are limited in rotation relative to the tray by a rotational stop feature in the receptacles that engages with the ribbed exterior portion.

Abstract: Flow cytometry investigation and flow cytometry result analysis to determine an optimized dilution factor range for flow cytometry investigation of a target sample fluid stock using a flow cytometer. The optimized dilution factor range may be determined using a screening assay module of a flow cytometry system to analyze flow cytometry results determined to fall within a dynamic range of a flow cytometer to determine the optimized dilution factor range for a given flow cytometer to investigate a given target sample fluid stock. In turn, a titer assay module may be executed to prepare particle titer results based on optimized target fluid samples provided within the optimized dilution factor range. The screening assay module and/or the titer assay module may provide automated data processing with data notifications and confirmations to provide robust data analysis.
