Multi-sample nanoparticle size measurement


Products > Analytical > Particle size distribution > nanoSAQLA


This is a particle size analyzer using DLS(Dynamic Light Scattering) method and molecular weight analyzer using SLS(Static Light Scattering) method.

Various functions are included to improve quality management.

The new optical system is able to measure multiple samples at one time with a wide concentration range from dilute to concentrated.

In addition, it is a new product not immersed in the liquid(non-immersion type), so contamination is not an issue and up to 5 samples can be measured without stopping, when used without the auto-sampler.

  • Simple and quick one-time setup of up to 5 samples each under different conditions

  • Measures both dilute and highly concentrated samples

  • Measures in 1 min.

  • Includes temperature gradient function

  • Contamination-free continuous measurement

  • Light and compact which is essential for laboratories

AS50(auto sampler)

  • Able to set up to 50 samples in a row

  • Adds samples as measure

  • Set samples in place easily

  • Replaces up to 50 samples at once

  • For organic solvents(glass disposable cell)

  • Sample vol. should be over 0.4 ml
