Description

Beckman Coulter Delsa 440SX Laser Particle Size Analyzer LDV w/Remote Power Supply

Benchtop laser Doppler velocimetry (LDV) instrument for measuring particle size distribution and electrophoretic mobility. Performs simultaneous multi-angle analysis using a Class 1 laser system.

Specifications & What's Included

  • Particle size range: 10 nm – 30 µm
  • Electrophoretic mobility range: 0 – 10 cm/V·sec
  • Five beam stop angles: 7.5°, 15°, 22.5°, 30°, plus main
  • Remote power supply: 115V, 720W output; 100–240 VAC input (50/60 Hz selectable)
  • Interfaces: DB-25 computer connection, 4 BNC AGC output ports
  • Includes Coulter Delsa 440 remote power supply; software not included

Applications

The Delsa 440SX was used in pharmaceutical, chemical, and materials research for characterizing latex dispersions, liposomes, emulsions, pigments, polymers, proteins, and bacterial suspensions. This analyzer type supported quality control workflows and formulation development across industrial and academic laboratories.

Condition: For Parts or Not Working
This Beckman Coulter Delsa 440SX Laser Particle Size Analyzer is being sold AS-IS for parts or repair. We were unable to test it, so no functionality is guaranteed. The unit includes the Coulter Delsa 440 Remote Power Supply but does not include the software required for operation — this is hardware only. The main instrument and power supply show typical wear consistent with lab use; the cabinet surfaces are intact with no major damage visible. Cabling, the optical arm assembly with Unitron eyepiece, and the interconnect harness are present. Ships via freight. Please view our photo set and contact us if you have any questions.
