Wyatt Mobius WMOB-09 DLS/ MP-PALS Advanced Analytical Instrument

The Wyatt Mobius WMOB-09 is an advanced analytical instrument for the characterization of nanoparticles, colloids, proteins, polymers, and other dispersions. The system combines Dynamic Light Scattering (DLS) for determining hydrodynamic particle size with Mobility Particle Analysis by Phase Analysis Light Scattering (MP-PALS) for highly accurate measurement of the zeta potential. Thanks to its high sensitivity and reproducibility, the instrument is suitable for applications in the pharmaceutical industry, biotechnology, nanotechnology, materials research, and academic research.

The system is supplied with supporting documentation, a PALS Certificate of Performance, QELS Certificate of Performance, Mobius Dip Cell Certificate of Performance, the software installation disc, and a valid software license.

In addition, the original Wyatt transport cases are included, as well as the Mobius Dip Cell (serial number DC-2561), the cuvette (serial number JC-0397), the Dip Cell plug, cleaning paper, tubing, and various original accessories and parts. A detailed photo report and a Packing List (PDF) are available as an attachment.

Note: The instrument is in good working order. The only known issue is that the lid does not close completely; this is easily resolved by placing a small weight of approximately 250 grams on the closure during use. Technical specifications
