Description:

Beckman 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!
