New 561 nm laser –

At the beginning of November 2013, the FACS Aria II was upgrade to FACS Aria III.  This upgrade includes the replacement and incorporation of a next-generation cuvette in the flow cell. Its design helps ensure that lasers are precisely focused on the sample stream, that they generate the greatest signal, and that the maximum amount of emitted light is collected. Furthermore, we added an additional laser, the 561nm (Yellow-Green) laser that provides the capability to efficiently excite fruit fluorescent proteins such as mCherry and mTomato as well as YFP.

Another advantage of the 561nm laser is the ease of separation of two commonly used fluorochromes, FITC and PE, resulting in the elimination of spillover between their emission spectra.


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 multiwell 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.

Digital Electronics

The BD FACSAria III cell sorter uses digital electronics to acquire data at rates up to 70,000 events per second for up to 8 parameters, with linear results over a broad dynamic range.



Aseptic sorting of events.
