Physical test methods
Our services
Organic and inorganic substances can be characterized unambiguously on the basis of physical parameters. We offer a wide range of physical test methods for determining parameters such as the color number, the density of liquids and solids, the melting point, dynamic and kinematic viscosity etc. We thus contribute to your process quality assurance. Using thermoanalysis, we can also investigate the melting and crystallization behavior, glass transition temperature and purity of your products.
Your advantages
- We offer all the physical methods needed for testing solids and liquids and can thus make an important contribution to the quality of your products, taking into account all legal requirements.
- You can focus on your core processes and thus increase your productivity.
- You choose only those services you actually need, thus minimizing your costs.
Our strengths
We can be on call around the clock to perform all the analyses and assessments you need when you need them.
Our range of methods means you only need one supplier for all your quality testing: for purchased goods, intermediates and sales products.
We are accredited to ISO 17025. Tests and procedures in accordance with GLP and GMP guidelines are an integral part of our work.
Service details
- Measurement of the color number (Hazen, iodine, Gardner)
- Measurement of density in liquids (oscillating tube method) and solids (pycnometer)
- Determination of the melting point
- Measurement of dynamic (falling ball, rotational, Brookfield) and kinematic (Ubbelohde) viscosity
- Determination of purity, melting point, glass transition temperature and crystallization behavior by thermoanalysis: differential thermal analysis (DTA), differential scanning calorimetry (DSC), thermogravimetry (TG)
- Determination of particle size distribution in dispersions (submicron range, fractionation by size and density), large particle counts (nib measurement) and measurement of average particle size by means of ultracentrifugation
- Tests in accordance with European, U.S. and German pharmacopoeias (Ph. Eur., USP, DAB)
