Results you can trust

At ALFATESTlab we are experts in particles and materials characterization. Our specialists benefit from a 30 years’ experience in physical characterization techniques for powders and liquid dispersions. Our team also includes experts in biomolecules characterization. Whatever your industry, our in-depth knowledge of the analytical techniques and our wide experience on any kind of material allow us to understand your analytical needs, retrieve the answers you are seeking for and deliver results you can trust.

ALFATESTlab offers contract analytical services according to ISO 17025 and based on a unique set of analytical techniques, complementary to each other, both for materials science and biosciences:

  • Particle size
  • Particle shape & transparency
  • Surface area BET (multipoint and single point)
  • Porosity (micro, meso and macro)
  • Density (real, bulk and apparent)
  • Moisture (and any other liquid) sorption properties
  • Powder rheology
  • Viscosity & Rheology of liquids and pastes
  • Thermal analysis DSC and TGA
  • SEM high resolution images & elemental analysis (EDX)
  • Stability & Shelf life studies - Cloud point
  • Particle size reduction
  • Nanosystems characterization: size Zav, Zeta potential, concentration
  • Sensory analysis (e-nose)
  • Molecular weight
  • Biomolecules size & aggregation
  • Exosomes and EVs: size, count, concentration, phenotype, cargo, etc.
  • Cell rupture
  • Label-free Biomolecular interactions (without purification)


What we can do for you

ALFATESTlab mission is to provide expertise on both analytical techniques and applications to offer our customers a complete peace of mind on the accuracy and reliability of their characterization processes. 

Our laboratory in Cernusco Sul Naviglio near Milan (Italy) is equipped with the latest equipment, our customers are welcome to assist to the tests if interested in instrumentation set-up (upon request).

The scientific and technical support is optimized whether our customer refers to ALFATESTlab for a single analysis, a long-term analysis contract, or a method development. Thanks to the in-depth knowledge of a wide range of materials, industries and analytical techniques, ALFATESTlab can develop and validate analytical methods according to specific customer needs and support customers in the verification and transfer of analytical methods for the following industries:

  • Pharmaceutical
  • Cosmetic & Consumer products
  • Inks, paints & Coatings
  • Speciality chemicals
  • Additive manufacturing
  • Ceramics 
  • Bulding materials
  • Polymers & Plastics
  • Food & Drinks
  • Automotive/ Aereospace
  • Electronics
  • Petrochemical
  • Energy
  • Failure Analysis
  • Fibers, Filters & Membrane
  • Nanotechnology
  • Microplastics

Analytical method development, validation, transfer

Our team is available for the development of accurate and robust analytical methods for the characterization of any type of material. The development of the analytical method is conducted according to the guidelines and regulatory reference requirements. The experimental design is first shared with the customer in order to meet his requirements as well as specific corporate quality requirements. At the end of the project our laboratory will issue a report including results of all the tests and analysis performed and the complete description of the optimized analytical method.

Our team can also support our customers in the validation of analytical methods. Validation can be performed on a method developed by our laboratory,  by the client himself or on a transferred method. Our services include the development of a validation protocol based on specific quality requirements, the execution of the tests and the issuing of a complete validation report together with the validated method.

The transfer of a method, to ensure consistent results between laboratories, requires a transfer project with the definition of transfer tests and acceptance criteria. Our experts can guide our customers in the choice and execution of the most appropriate strategy for an efficient transfer of the analytical methods.
