WPA 80-3003-75 Model Biowave II UV/Visible Life Science Spectrophotometer, 190 to 1100nm Wavelength, 5nm Spectral Bandwidth, 90-250VAC

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 control 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 can be measured using a factor, single-point calibration, or multi-standard curves. The multi-wavelength mode allows ratio calculations using absorbance values. In kinetics mode, the correlation coefficient is calculated for the duration of the assay, and the basic plot of absorbance against time can be supplemented with the result for δA/min. This slope can be multiplied by a factor to convert it directly to rate of reaction. The 5.0nm bandwidth is used for routine quality control measurements when high resolution is not 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 each 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.SpecificationsMeasuring principleDual-beam monochromatorWavelength range190 to 1100nmSpectral bandwidth5nmAbsorbance range-0.3 to +2.5AChamber capacity10mm cuvettesAbsorbance light sourceXenonPreprogrammed methodsNucleic acid, protein, and cell density measurementsUser-defined methodsUp to 99Computer interfaceRS-232Power requirements 90-265VAC, auto-detectingH is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.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 may have one or more 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.
