Beckman DU-65 UV/Vis Scanning Spectrophotometer 200-900nm Wavelength Scan
Manufacturer: Beckman Model: DU-65 UV/Vis Spectrophotometer P/N: 120651 S/N: 4310288 Description: Be (more)ckman Coulter DU-65 uv-vis spectrophotometer. The Beckman DU-65 is an instrument that combines optimized wavelength scanning with step-programmable capabilities and brings self contained versatility and productivity to the laboratory. The basic operation can be mastered in seconds with time saving features like storage of calibrations and auto-scaling of scans. With its Plug in Soft-Pacs, repeated analyses can be produced at the touch of a button with a variety of functions such as linear and non-linear calibration curves, wavelength scans, kinetic measurements, and gel-scans. These modules are available for various applications such as protein assays, DNA purity, tablet dissolution rates, and performance validation. No need of software or anything else - very comfortable wavelength scans with transmission and absorbance with the printer on top!
