Color measurement of liquid pharmaceutical products

Liquid medicinal products include solutions, suspensions, emulsions, syrups, drops, infusions and the contents of gel capsules. Cold remedies such as cough syrup, nasal spray or homeopathic drops as well as solutions and infusions. Doctors, pharmacists and patients also assess the effect of a medicine in terms of its color and appearance.

If this differs from the usual appearance, this indicates a lack of quality or limited durability. Liquid APIs, injectables and other liquid proteins also have to comply with pharmaceutical guidelines. HunterLab spectrophotometers provide reliable, accurate color values and color numbers – even with minimal sample quantities.

Application example:

Color measurement of liquid biopharmaceutical products with the UltraScan VIS spectrophotometer

In the pharmaceutical industry, the precise determination of the color of transparent liquid products is crucial in development and quality management. Accurate color measurement in transmission according to CIE and ASTM standards is essential to qualify the color of liquid APIs, injectables and other liquid products according to international pharmaceutical guidelines. In particular, the exact assignment of internationally defined color numbers must be guaranteed even for the smallest sample quantities. HunterLab color measurement offers the perfect solution to meet these requirements, providing the pharmaceutical industry with reliable, accurate color values and color numbers –...

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
