You may have noticed that the Zetasizer instrument range is available in two different optical configurations: the ‘traditional’ 90 degree setup and the ‘NIBS’ 173 degree setup. An obvious question for a dynamic light scattering (DLS) user is: “Will I get the same results…READ MORE >

Light scattering with the Zetasizer owes part of its success to the ease of use integral in its default DTS software. The intuitive windows environment lets you setup a measurement (either in “manual” or in “standard operating procedure” mode) and…READ MORE >
