The Biochrom WPA 80-3003-75 Biowave II UV/Vis diode-array spectrophotometer has a 190 to 1100nm wavelength range, a 5nm spectral bandwidth, and a xenon lamp, and is used for quality keep an eye on and general purpose laboratory testing. The instrument performs fixed wavelength, kinetics, and concentration measurements, and flash scans. Pre-defined methods include nucleic acid quantification (DNA, RNA and oligonucleotides), protein assays (BCA, Biuret, Bradford, and Lowry) and for cell culture density measurements. The instrument accepts up to 90 user-defined methods. Concentration will also be measured the usage of a factor, single-point calibration, or multi-standard curves. The multi-wavelength mode allows ratio calculations the usage of absorbance values. In kinetics mode, the correlation coefficient is calculated at some point of the assay, and the basic plot of absorbance against time will also be supplemented with the result for δA/min. This slope will also be multiplied by a factor to convert it directly to rate of reaction. The 5.0nm bandwidth is used for routine quality keep an eye on measurements when high resolution isn’t required. The xenon lamp provides an internal standard for wavelength accuracy verification, and the xenon flash lamp and beam splitter provide real-time reference beam correction with every lamp flash. The instrument accepts 10mm, 20mm, and 40mm pathlength glass, quartz, or plastic cells, and low-volume UV cuvettes. The graphical LCD displays test results directly on the instrument, and provides wavelength scans, kinetics, and standard curve functionality. The Windows-compatible Grafico PC utility software package allows students to capture, print, and interpret results, including wavelength scans and data export to spreadsheet software. The software includes an educational tutorial on UV/Visible spectrophotometry.

A spectrophotometer is a device used to measure and analyze aspects of light absorption in liquids and solids. Readings are displayed in digital or analog format. A spectrophotometer can have a handheld body for field use, or a bench-top body for laboratory applications. It will have a number of adapters to enable it to measure surfaces or liquids. A spectrophotometer is used for testing and measuring in anatomy, chemistry, agriculture, process plant, food and beverage making, homeland security, and educational applications.
