Ultrahigh-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.

FR-X Overview

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.
