Rigaku generators
Engineering and manufacturing advanced X-ray generators is a core competency at Rigaku. To meet the various current and future needs of structural biology, Rigaku offers a range of generators, from a compact second generation microfocus sealed tube system to the brightest microfocus rotating anode generator available today. Rigaku generators have a long-established reputation for outstanding reliability and performance. The latest Rigaku sources produce unparalleled X-ray beam brightness, with low divergence, for superior data with small or poorly diffracting crystals.Brilliant X-ray sources
Rigaku X-ray generators are mated to X-ray optics to afford an optimized X-ray source. As illustrated in the comparison table, the products offered for protein crystallography span from the modest X-ray brightness afforded by a conventional sealed X-ray tube to the synchrotron-class flux delivered by the ultra brilliant FR-E+ SuperBright™ microfocus rotating anode X-ray generator.

Unparalleled productivity
Rigaku is the leading provider of home laboratory X-ray sources for macro-molecular crystallography. A statistical analysis of X-ray crystal structures submitted to the Protein Data Bank (PDB) showed that structures solved with Rigaku home laboratory X-ray generators comprised 17% of all submitted structures for 2005, the latest year of complete data. Of structures solved with home lab sources that year, 89% were done using Rigaku equipment. The data conclusively demonstrate that Rigaku structural biology customers are collectively the most productive, far exceeding the nearest competitor in the home lab market.
