Surface and interfacial tensiometry

For this service we offer a Sigma 701 force tensiometer (Biolin Scientific) with software for control, acquisition and data treatment for the measurement of surface and interfacial tensions, as well as the automatic determination of critical micellar concentrations. It is equipped with Wilhelmy plate and Du Nouy ring accessories.
We also offer a SITE Spinning Drop Interfacial Tensiometer (Krüss) for determination of liquid-liquid interfacial tensions by the spinning drop method.

Customer benefits

  • Specialized in colloidal samples
  • ISO9001 certification for standard quality control system
  • Highly qualified and continuously trained staff
  • Adapted to customers’ needs

The services provided by the unit are very relevant for product formulation and quality control. Applications include surface and interfacial tension measurements of liquid systems. Also determination of ultra-low interfacial tensions (up to 10-5 mN.m-1) in colloidal liquid-liquid biphasic systems at controlled temperature.

Target customer

Public research organizations, academia and industry in the pharmaceutical, chemical, food and cosmetic sectors.

Evaluation of colloidal stability

For this service we offer a Turbiscan instrument (Formulaction) for the evaluation of colloidal stability. It measures turbidity by multiple light scattering, as a function of time along the vertical axis by both transmitted and backscattered light. It can analyse samples up to 95 vol% with a wide range of particle sizes (10 nm – 1 mm). The samples are placed inside a temperature-controlled chamber, and the measurements can be carried out from room temperature up to 60 ˚C.

Customer benefits

  • Specialized in colloidal samples
  • ISO9001 certification for standard quality control system
  • Highly qualified and continuously trained staff
  • Adapted to customers’ needs

The services provided by the unit are very relevant for product formulation and quality control.Applications include analysis of colloidal stability of emulsions, suspensions and foams and to determine whether there is sedimentation, creaming, flocculation or coalescence.

Characterization of materials by high resolution optical microscopy with spectral analysis and scanning electron microscopy

For this service we offer a CytoViva Hyperspectral Imaging System (HSI). The instrument combines enhanced dark field optical microscopy with high resolution spectral imaging. These integrated technologies have been designed to allow optical observation and spectral characterization of nanomaterials and cell matrices. There is no need of sample preparation in advance or fluorescent labelling to observe or characterize spectroscopically nanomaterials in complex media.
We also offer a BX51TRF6 Olympus Optical Microscope that can work with transmitted or reflected light. Different observation methods can be used: bright field, dark field, phase contrast, differential interference contrast, polarized light, and fluorescence. It includes two revolvers to work at short or long distances. Moreover, it is equipped with a digital camera (Olympus DP73) connected to the computer with a software that captures images and videos. A heating stage is available for observations at controlled temperature.
