Unchained Labs Stunner - UV and Dynamic Light Scattering

The Unchained Labs Stunner uses a microvolume UV - visible spectrophotometry - based analytical technique that is tailored for rapid protein and nucleic acid characterisation. A tiny sample (typically ~2 uL) is loaded into a disposable microcuvette (the "Stunner plate"), where the instrument measures absorbance across a UV/Vis spectrum (roughly 230 - 750 nm). From this, it simultaneously determines concentration (via absorbance at 280 nm for proteins or 260 nm for nucleic acids), purity (e.g. A260/A280 and A260/A230 ratios), and turbidity/aggregation (via dynamic light scattering at higher wavelengths such as ~320 nm). The technique relies on the Beer - Lambert law to convert absorbance into concentration, while deviations in the spectrum indicate contaminants or aggregates. Compared with traditional cuvette or NanoDrop-style measurements, Stunner integrates multi-wavelength analysis and automated data handling to provide a quick, high-throughput snapshot of sample quality in a single measurement.
