• Preprogrammed methods for DNA, RNA and protein analysis • USB for saving results and method • Icon-driven software and easy-to-use navigation system provide intuitive usability

SP-300 Series Life Science Spectrophotometers have all the features of a standard spectrophotometer plus features dedicated to life science analysis. Preprogrammed methods measure ssDNA, dsDNA, RNA, and oligonucleotide concentrations using wavelengths recorded at 260, 280 and 230 nm with an optional correction at 320 nm. For measuring protein concentrations, SP-350-BIO and SP-350-NANO models are preprogrammed with methods for Bradford, Lowry, Biuret, Bicinchoninic Acid (BCA), and Direct UV assays. The lid of the instrument includes a large graphical display with the option of an integrated printer...

SP-300 Series Life Science Spectrophotometers Measurement Modes Cell density measurement mode – bacterial cell cultures are routinely grown until the optical density at 600 nm reaches approximately 0.4, which indicates the optimum cell number for harvesting. This measurement mode enables cell growth to be monitored by measuring absorbance. Measurements can be performed at 600 nm, 595 nm or any other user selected wavelength. Purity scan measurement mode – this measurement mode is used to check the purity of nucleic acids. This is especially useful for RNA samples where impurities may be present...
