Features at a glance
Brookhaven’s NanoBrook 173 instrument is the go-to-solution for characterization of proteins, antibodies, nanoparticles, macromolecular assemblies and other molecules/particles of small sizes. The NanoBrook 173 uses backscattering detection for the highest sensitivity and accuracy optimized for molecules and particles less than a few tens of nanometers.
Reliable, Accurate, and Accurate Analysis
The new NanoBrook 173 protein and particle size analyzer incorporates all you need for fast, routine, sub-micron measurements. Based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, most measurements only take a minute or two.
Dilute suspensions, on the order of 0.0001 to 1.0% v/v are prepared, using suitable wetting and/or dispersing agents, if required. A small ultrasonicator is sometimes useful in breaking up loosely-held agglomerates. Sample volumes as small as 50 µL are used. Sample is recoverable. Disposable, polystyrene U-shaped cells are used for aqueous and simple alcohol suspensions. Just a few minutes are required for the sample and cell to equilibrate with the actively controlled temperature environment inside the NanoBrook 173.
