Fully tested using a diluted commercial wood-glue dispersion. The system repeatedly measured an effective hydrodynamic diameter of approximately 1,000 nm with polydispersity below 0.10. Results were stable and repeatable.
System Includes
1x Brookhaven 90Plus
1x HP EliteDesk desktop PC w/ 90Plus Particle sizing software
1x USB Cord
2x Power adapters
Peripherals seen in photos and video are not included, cuvette is not included in purchase. Peripherals can be bought separately if desired.
The particle sizing / DLS function has been tested and is working properly. The unit communicates with the included computer and Brookhaven 90Plus software and successfully performs particle-size measurements. We have also physically inspected the instrument and verified that the Brookhaven ZetaPlus electronics/boards are installed internally. The electrode connection is present inside the sample chamber as well. Please note: the ZetaPlus / zeta potential function has not been functionally tested, because we do not have the required Brookhaven zeta electrode assembly. No zeta electrode assembly is included. The installed Brookhaven software is expected to be compatible with the ZetaPlus hardware, but zeta operation has not been verified. Brookhaven still sells the cuvette electrode inserts if you require Zeta analysis.
From Brookhaven,
"The 90Plus performs fast, routine submicron particle size measurements on a wide variety of samples and concentrations. It is an ideal instrument for measuring colloids, latexes, micelles, microemulsions, proteins, and other nanoparticles. Based on the principles of dynamic light scattering, most measurements only take a minute or two."
