MPL (multi-platform loader) option for the Beckman Coulter Cell Lab Quanta SC Flow Cytometry System enables accurate, quick handling of a range of plate types, including 96- (flat, round or deep wells) and 384-well plates, chilled plates, or a 24 ViCell sample cup holder. Enhancements to the QuantaSC software enable easy setup and programming of the MPL, along with an expanded database capability. The MPL also acts as a pipetting station, aspirating from eight sample cups on a reagent tray. Applications for the MPL option include high-throughput cell-based assays and cell viability analyses in drug discovery. The Quanta SC is a personal flow cytometer that combines side light scatter detection and a third fluorescent channel with Coulter volume measurement to deliver accurate, multi-parameter cell counting and sizing. Up to five parameters can be studied at once with the system.
