Physical Standards

Physical standards are used in applications that examine the physical properties of the analyte. Examples include the determination of refractive index, density or speed, or the UV / VIS spectroscopy. To interpret obtained signals or values correctly, appropriate standards must be measured.

In the following you can find physical standards of all leading manufacturers. If you do not find the appropriate standards or reagents or have a question, we’ll be glad to help you.
