Our Services (11)


ic

Particle Size Distribution

Price on request

Guaranteed error-free with our NanoLab 3D. This instrument features our Moduled 3D technology, enabling accurate measurements at any concentration. Samples can be characterized in their native state, with no need for dilution.

Sample volume: 4 uL to 4 mL

Temperature range: 4°C to 85°C


ic

Particle Analysis and Characterization

Price on request

The choice of the technique highly depends on the nature of the system and the parameters desired.

Dynamic and Static Light Scattering are techniques of choice to characterize:

- particle size

- particle shape

- molecular weight

- sample structure

- aggregation

- many more on demand


ic

Rheology Analysis

Price on request

Contact-free rheology with our DWS RheoLab.
This is a powerful instrument that provides access to the sample’s viscoelastic properties over an unmatched frequency range while requiring only small sample volumes. Since the measurements are contact-free and non-destructive, the use of a tightly sealed sample cell allows studies of stability or shelf-life over long periods for highly viscoelastic and fragile microstructures. Based on the powerful DWS  Microrheology technique, the RheoLab is ideally suited for a wide range of viscoelastic samples, including polymers, microgels, protein solutions, emulsions, particle suspensions, dairy, and cosmetic products.


ic
