Malvern Panalytical - Zetasizer µV

Manufactured by  Malvern Panalytical
Follow this Equipment

A highly sensitive batch DLS instrument and a powerful SEC-LS detector, in a single package.

Add the power of advanced light scattering technology to your size exclusion chromatography system (SEC-LS), or use in cuvette mode for large aggregate detection. Uses dynamic light scattering (DLS) to measure molecule size, and static light scattering to determine molecular weight.
