Up to four-way bulk sorting devices for a variety of tube sizes.

Automated Cell Deposition Unit (ACDU) for sorting to multi-well plates or microscope slides



Optical System: Patented BD OctagonTM and TrigonTM technology.

Laser excitation and filters (see FACSAria III configuration in the related links):
Lasers: 488-nm, 633-nm, 561nm, and 407-nm.
15 parameters: forward scatter, side scatter, 5 fluorescent detectors of 488-nm, 2 fluorescent detectors of 633-nm, 4 fluorescent detectors of 561-nm, and 2 fluorescent detectors of 407-nm.

Specifications and performance


Fluorescence Sensitivity

FITC: 125 molecules of equivalent soluble fluorochrome (MESF-FITC)

PE: 125 molecules of equivalent soluble fluorochrome (MESF-PE)


Fluorescence Resolution

Coefficient of variation PI-Area of <3.0%, full G0/G1 peak for propidium iodide (PI)-stained chicken erythrocyte nuclei

Coefficient of variation Hoechst-Area of <3.5%, full G0/G1 peak for Hoechst-stained chicken erythrocyte nuclei


Fluorescence Linearity

Doublet/singlets ratio for CEN stained with PI = 1.95-2.05 detected off the 488-nm laser or Hoechst = 1.95-2.05 detected off the 407-nm laser


Forward and Side Scatter Sensitivity

Sensitivity enables separation of fixed platelets from noise, identification of bacteria, and 0.5-micron beads.


Forward and Side Scatter Resolution

Scatter performance is optimized for resolving lymphocytes, monocytes, and granulocytes.


Sample Acquisition Rate

Maximum acquisition rate: 70,000 events per second with 8 parameters, 12 compensation pairs. Maximum rate < 70,000 events per second with more parameters, > 100,000 events per second with fewer parameters.


Sorting options:

Two- and four-way sorting into microtubes, 12 X 75, and 15 mL tubes

ACDU (automated cell deposition unit) for sorting into multi-well plates and onto microscope slides

Sample injection chamber for various sample input tubes, including microtubes, 12 X 75, and 15 mL tubes. Includes sample agitation and temperature control.


Signal Processing

  • Digital electronics with 10 MHz sampling frequency
  • Up to sixteen acquisition channels with up to four spatially separated laser beams
  • 18-bit data acquisition for area signals
  • Inter- and intra-beam compensation on-line and post-acquisition off-line
  • Height, width, and area measurement available for all parameters
  • Time parameter available for kinetic studies (Calcium)
  • Ratio measurements between any two parameters from any laser


Nozzle selection and design

An expanded set of nozzles lets users sort a wide range of particle sizes. Four nozzle sizes are supported: 70, 85, 100, and 130 microns.
