ZE5™ Cell Analyzer

The ZE5 Cell Analyzer is an innovative new flow cytometer with flexible configurations to meet a broad range of experimental complexities and throughput needs. Whether it’s a low-complexity, or a high-complexity experiment, the ZE5 Analyzer has up to 30 parameters and provides a truly expandable flow cytometer. This flexibility makes the ZE5 Analyzer accessible for novice flow cytometry users yet flexible enough for the most experienced flow cytometry professionals

A fully integrated sample loader with the ability to handle tubes or plates without an instrument hardware change enables true walk-away functionality. Features such as a stat tube station, fluid and reagent hot swap capability, and automated startup and QC allow for continuous operation and maximization of instrument running time for any busy core lab.

The ZE5 Analyzer was created by gathering input from leading flow cytometry experts across the world and was designed to address user-reported gaps in currently available systems. Some of these features include:

Flexible loading options

  • Fully automated sample acquisition from 5 ml sample racks or microplates (up to 384 wells) plus a stat tube option for urgent samples
  • Patent-pending automatic calibration and built-in detection for probe crashes
  • Integrated, programmable wash station reduces carryover and time between runs
  • High-throughput mode can analyze a 96-well plate with < 0.5% carryover in less than 15 minutes
  • Temperature-controlled loading
  • True plate shaker agitation
  • Volumetric sample uptake allows automatic concentration calculation and absolute counting without beads
  • No dead volume requirement, no wasted aspirated sample, and the ability to automatically return unused sample to the tube or well
  • Single-tube load position provides the flexibility to interrupt and load additional samples
  • Add reagents to your samples in real time for kinetic experiments
  • On-board calibration beads provide automated QC without user intervention to reduce setup time
  • Volume tracking for on-board beads provides an alert when replacement is needed
  • Innovative continuous sampling allows unlimited volume acquisition at a stable flow rate

Best-in-class and scalable optics

  • Up to five spatially separated lasers ranging from 355 nm to 640 nm
  • Integrated beam shaping and focusing optics for each laser increases excitation stability
  • Up to 27 fluorescence detectors with FSC/SSC and optional small particle detector (FSC from 405nm laser)
  • Patent-pending ZE5 EYE technology profiles the instrument with 10 LEDs of unique wavelengths
  • ZE5 EYE technology also enables system-to-system detector calibration
  • Dual forward-scatter design allows standard FSC detection while simultaneously collecting small-particle or alternate-wavelength scatter data
  • Field upgradable with modular excitation and detection components

Integrated and easy-to-use fluidics

  • Patent-pending sample delivery system allows stable, continuous flow from 0.0025 to 2.5 µl/s
  • High-velocity sheath flow delivers unparalleled analytical throughput
  • Hot-swappable bulk fluid bottles
  • Built-in ports to connect to a house DI and waste system
  • On-board cleaner and additive bottles
  • Bidirectional flow to the cuvette
  • Sleep mode conserves laser hours and fluids when the system is not in continuous use

Innovative electronics provide the industry’s highest-quality data

  • Measured peak, area, and width parameters available simultaneously for every channel
  • Proprietary digital processing with 24-bit data maximizes dynamic range and reduces channel noise for superior dim-population resolution
  • Zero dead-time processing with dynamic window extension
  • Massively parallel, pipelined architecture eliminates hard aborts
  • Unassisted laser-delay system configures optimal delays
  • Real-time hardware system control
