working standards

We offer a broad portfolio of working standards for pharmaceutical quality control. Our working standards come with proof of identity and determined content. Because our working standards are derived from fully qualified primary reference standards, they can be used for testing of drug substances, intermediates and drug products without restrictions. Regular retests against the corresponding primary reference standard guarantee the content of the working standard over a defined period of time.

We offer our reasonably-priced working standards in quantities suited for one analysis.
Here you can find more benefits!

They are available immediately or at your desired date. If you cannot find your working standard, do not hesitate to contact us.
