The Cole-Parmer SP-400-VIS diode array spectrophotometer incorporates the latest scanning technology to offer reliability and easy function.
- Scanning diode array technology provides rapid, reliable scanning from 335 to 800nm in less than 10 seconds with excellent wavelength reproducibility
- Colour touchscreen operation with 100mm wide display, ensuring full spectrum scans, quantitation curves and Kinetics runs can be viewed easily
- Reversed optical architecture is not affected by ambient straylight, allowing measurement with the lid open and tall sample vessels to be accommodated
- Diode array detection with 1024 elements and tungsten-halogen lamp gives good intensity over the visible range of the spectrum with low noise and drift
- Two, separate USB ports are provided for data storage (front) and printer connectivity (rear)
- Built-in, convenient cell rack moulded into the instrument body
