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!

Artificial single-crystal leucosapphire rods. Produced in USSR, 1985-1988. There are about 80 big (more) rods with length from 50 to 295 mm and diameter from 14 to 20 mm. On the photos 1-4 the rod with dimensions 251*16 is shown as example. And also 178 small rods with length 20...50 mm and diameter 1...3 mm are available. One end surface is polished and another end surface is matted. Side surface is also matted. There are no defects (cracks, splits) observed. Ideal light transmission! Can be used as a light-guide in harsh environment (high-temperature, corrosion, etc) or as a raw material for optical components such a lens, windows production. The price mentioned in advertisement reffers to the rod 251*16 mm.
