See further with Chirascan
Confidently characterize structure, interactions, and stability across biologics and small molecules.

See your molecules more clearly than ever
Chirascan builds on the foundations of traditional circular dichroism with deeper, multi-dimensional insights and built-in analytical precision. While many spectrometers focus on basic secondary structure, Chirascan empowers you to resolve tertiary changes, thermodynamic transitions, kinetics, and higher-order structural differences with the sensitivity, automation, and statistical confidence needed for advanced biological and regulatory workflows.

Determine innovator HOS characteristics. CD analysis of tertiary structure in a highly absorbing chiral formulation buffer suggested differences in tryptophan region of Fab fragments from different innovator lots.
Sensitivity that reveals the subtle
Detect even the smallest structural shifts with advanced, low-noise optics with the most sensitive CD instrument on the market. Chirascan’s optimized optics and detectors deliver industry-leading sensitivity across UV and near-UV wavelengths, enabling detection of subtle tertiary changes and low-signal transitions that can be challenging for conventional CD spectrometers to resolve.
Automation that saves you time
Unattended runs, automated measurements, and cuvette washing let you keep experiments moving without hands-on time. Spend less time managing the instrument – and more time interpreting meaningful data.

Deep insights in every experiment
Collect CD, absorbance, fluorescence, and full-wavelength thermodynamic data in a single, integrated workflow without having to switch instruments, as is often required with traditional CD systems. With precise temperature control and integrated analysis, you get more information in less time and make faster, evidence-backed decisions.
