Our economical scanning spectrophotometers produce first-rate results using any UV/visible analytical method. High-quality components and systems enable superior resolution, accuracy, and reproducibility. Specify method parametric setup using simple on-board keypad controls or from computer. View spectral graphics on backlit LCD. Sample compartment accommodates up to 8 cuvettes with pathlengths up to 100 mm.
Store up to 30 user methods in non-volatile memory. Programmed methods include DNA/protein ratios (260/280 nm or 260/230 nm). Specify up to 10 wavelengths for multiple sample analysis or use the GLP protocol to verify wavelength and transmittance. Study reaction kinetics for up to 12 hours with sampling intervals down to every 0.5 seconds; use post-run re-scaling and curve/segment targeting to refine rate calculations.
