The laboratory standard circular dichroism instrument

Suitable for studying chiral molecules of all types and sizes, this Chirascan CD spectrometer has featured in thousands of publications since its introduction in 2005. Often used to analyze biomolecules, Chirascan data contributes to a deeper understanding of biomolecular characteristics, mechanisms and interactions.
