The SP-400 series of spectrophotometers are the first scanning spectrophotometers in the Cole-Parmer range that utilize diode-array technology to produce exceptionally fast results. The series includes two models: the SP-400-VIS model covers a wavelength range from 335 to 800 nm with a spectral bandwidth of 7 nm, and the SP-400-UV model covers a wavelength range from 198 to 800 nm with a spectral bandwidth of 5 nm. Both spectrophotometers are ideal for a variety of applications in education and routine testing in clinical, veterinary, pharmaceutical, and QC laboratories.
