The multi-element detectors on these scanning spectrophotometers measures the entire wavelength range at once, reducing wait times. Plus, each dataset contains readings from the complete spectrum, making the data readily available for future analysisThe USB port on the rear connects with a printer (order separately), while the USB on the front accepts flash drives for data storage, quantitation curve uploads, and firmware updates. Measurement modes include photometrics, concentration, optical density (O.D. at 600 nm), quantitation, spectrum scanning, and kinetics. Incl:10 x 10 mm cuvette holder, USB memory stick, and power adapter with three plugs (US, Euro, and UK). Fast scan speedas short as 3 seconds. Wavelength range: 198 to 800 nm. Spectral bandwith of 5 nm. Wavelength Accuracy 2.0 nm
