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! Specifications: Operating Principle: Double beam spectrometer for the UV/VIS region, with  microcomputer electronics, keyboard entry and vacuum fluorescence display.Monochromator: Holographic concave grating with 1053 lines/mm.Radiation: Prealigned Deuterium and Tungsten halogen lamps with automatic lamp  switching.Wavelength: 200 nm – 900 nm.Scanning Speed : 500 or 750 nm/ min selectableStray Radiation: Measured with a 2 sec response time< 0.03 %T at 220 nm< 0.02 %T at 340 nm, 370 nm.Wavelength Accuracy: +- 0.3 nm at Deuterium peak 656.1 nm.Reproducibility: +- 0.1 nm.Spectral Slit Width: 2 nm.Photometric Accuracy: +- 0.005 A at 1 A (measured with NBS 930 filters).Reproducibility: +- 0.002 A at 1A.Range: -3 to +3 A.Stability: < 0.0003 A/h (at 500 nm, 1 sec response time, after warmup).Baseline Stability: +- 0.001 A (200-900 nm at 0 A, 2 sec response time, 240  nm/min scan speed.Noise: < 0.0003 A (at 0 A, 500 nm, 2 sec response time) All Intelligence in the Instrument with direct keyboard input. . No need for  external PC, Software or anything else - very comfortable wavelength scans with  transmission and absorbance with the printer on top giving you direct print-outs  of any made scan.
