Ultra high-intensity microfocus rotating anode X-ray generator
Highest usable X-ray flux available for the laboratory researcher
The FR-X was designed to be utilized in structural biology and material science, and provides the highest usable X-ray flux available for the laboratory researcher. The new design provides 20% more flux compared to the previous model as well as a new direct-drive anode that reduces maintenance expense considerably. The standard dual port design can be coupled with an optional dual wavelength anode to provide the ultimate in experimental flexibility and end-station utilization.
Reliable, Dependable, Powerful
These are words that have become synonymous with Rigaku’s high powered rotating anode X-ray generators. Rigaku introduced the first rotating anode X-ray generator in 1952 and has continuously advanced the technology since. These generators have greatly impacted many fields of science. As an example, ninety percent of the protein structures deposited in the Protein Databank (PDB) that were determined in a home lab were solved from data measured with a Rigaku rotating anode source.
Engineered to operate 24/7
The FR-X design is based on decades of proven craftsmanship to provide outstanding instrument reliability. With a Rigaku X-ray source you do not take a chance that your X-ray source will fail to provide you with the uptime and performance that your research demands.
Dual ports for maximum flexibility
Perhaps the most important feature of the FR-X is the standard dual port configuration. When investing in a high-end X-ray source, only a dual-port configuration allows one to obtain the most from their investment as well as take full advantage of the photons that are generated. Whether you have the need for two experimental end-stations now or not, there is no reason to limit the expansion of your facility in the future.
Optional dual wavelength configurations
Rigaku pioneered the use of multi-metal anode targets and the FR-X continues this tradition by offering optional dual banded anode targets. This allows one to design a multiple wavelength experiment where the sample can remain in place between switching of wavelengths. It also expands the capabilities of the experimental setup by increasing the types of samples that can be measured.
- Highest flux of any microfocus rotating anode X-ray generator
- Direct drive rotating anode for lower maintenance expense
- Smallest focal spot size of any rotating anode X-ray generator (70 μm diameter circle)
- Small beam provides greater flux density and less background for small samples
- Increases laboratory throughput by allowing for shorter exposure times and faster data collection
- Collect full data sets on samples where only low-resolution reflections were seen on a standard system
- Screen crystals where no diffraction is seen using a conventional rotating anode or sealed tube source
- Optional dual wavelength anodes with computer controlled wavelength selection
- Choice of anode materials: Cu, Cr, Mo, Cu/Cr, Cu/Co
The Rigaku FR-X is the most intense home laboratory X-ray source available today, providing brightness exceeding some second generation bending magnet synchrotron beamlines. Ideal for many applications requiring a very bright X-ray beam, the FR-X provides the flux you need, where you need it: on your sample.
