The only true screening platform for suspension cell and bead formats
Based on Flow…Built for Screening: The iQue Screener transforms flow cytometry detection into a true screening platform by eliminating the manual nature and "expert-required" aspects of this method. Automated processing and analysis of plates in minutes.
Better Data than Plate Readers: The iQue Screener generates multiplexed data — up to six measurements per object — allowing complex biologies to be monitored with up to 60,000 data points generated per second.
A High Content Complement to Imaging: Suspended objects are difficult to measure with imaging. The iQue Screener is optimized to sample suspended objects, at sampling rates (10,000 objects/second) that far exceed imaging methods. Every phenotypic screening lab should have both in their toolbox!

Features of iQue Screener & iQue Screener HD
Highest Throughput The iQue Screener can process a 96-well plate in as little as 3 minutes, 384-well plates in as little as 12 minutes. Designed for automated plate loading robots with large fluid reservoirs can process 30+ 384 well plates in a single run. iQue Screener HD can screen cells and beads in suspension using 1536-well plate format in 60 minutes — an industry first.
High Content Cell and Bead Data iQue Screener's detection has a large dynamic range (7 decades) with no adjustments necessary, simplifying screen set up and data collection. A wide open signal window allows the simultaneous collect of cells and beads in the same well.
Minimal Sample/Reagent Use iQue Screener can take as little as one microliter from each well with no dead volume allowing reagent and precious sample savings through volume reduction.
Intuitive, Interactive Screen Set up and Visualization iQue Screener uses our industry leading ForeCyt® Control and Analysis Software with plate-centric annotation and visualization makes getting the right answers easy. Gates are straight forward to set up, are linked, and update in real time for a truly interactive assay development experience that can be templated and applied to all plates in a run.
96, 384, and 1536 (iQue Screener HD only) well plates, V-, and flat-bottom, compatible with foil sealing to reduce evaporation (piercing probe). Plates meeting the Standards ANSI/SLAS 1-2004 through 4-2004, maximum height 35 mm.
