Zetasizer Nano ZS


  • Particle size measurements (0.6 nm – 6 μm) using PCS (Photo Correlation Spectroscopy)
  • Examination of particles suspended in water and non-water media.
  • Very small sample volume (approx. 1 ml) and short analysis time
  • Measurements in a wide temperature range (2-90oC)
  • Measurement of zeta potential of dispersed particles of sizes from 3 nm to 10 μm using LDV (Laser Doppler Velocimetry), M3 (Mixed Mode Measurement) and PALS (Phase Analysis Light Scattering).

Examples of use:

  • Analysis of particle sizes, polydispersity and zeta potential of nanomaterials in various dispersion media. Analysis of stability of emulsions. Stability characteristics of colloid systems. Analysis of aggregation-dispersion processes in suspensions of soils, minerals and biomaterials (e.g. bacteria, proteins), etc.
  • Measurements of particle sizes and/or the zeta potential in potable water, filtered liquids (for filtering performance), emulsion of foods, cosmetics, pharmaceuticals, suspensions of powders, dusts, pigments, toners, and various deposits

Mastersizer 2000


  • Determination of the particle size (granulometric) distribution in the range of 0.02 µm – 2 mm using laser diffraction methods
  • Low amounts of tested materials (from 0.5 to several grams).
  • Application of inorganic and organic dispersion media
  • Short analysis time

Examples of use:

  • Stability of soil aggregates. Dynamics of dispersion processes in various media. Determination of granulometric composition of soils, sediments and thin deposits
  • Determination of the granulometric distribution of soils, deposits, microorganisms and small organisms (i.e. algae, yeast, protozoa), powders, dusts and pollutants in various dispersion media. Determination of the particle size distribution in foodstuffs (e.g. beverages, fruit juices, starch, chocolate) and other materials

Morphologi G3


  • Measurement of particle sizes in the range from 0.5 µm to 2 mm using optical microscopy and image analysis
  • Determination of size distribution with precise determination of the number of analysed particles.
  • Particle size distribution based on many pre-programmed parameters (e.g. elongation, circularity, convexity and others).
  • Examination of dry powdered materials and their liquid suspensions
  • Colour microscopic photography of samples.

Examples of use:

  • Analysis of the size and shape of particles in dry and dispersed forms. Examination of the size, shape and count of synthetic or natural granular materials (powders, etc.), plant materials (e.g. seeds, plant roots, etc.), biomaterials and microorganisms
  • Measurements of the size, shape and count of particles – wide selection of materials (suspensions, deposits, filter contaminants, microorganisms, dusts, powders, microcapsules, granulates, etc.).

ULTRAPYC 1200e helium pycnometer


  • Measurements of volume and density of solids, powders and suspensions.
  • Sample volume range: 0.2-135 cm3
