Small angle X-ray scattering (SAXS) Kratky camera system
Protein solution structure determination
Rigaku's BioSAXS-2000 SAXS camera is designed specifically to meet the needs of the structural biologist. Based on a patented two-dimensional Kratky design, the BioSAXS-2000 takes up much less space than a conventional 3-pinhole camera but offers better flux characteristics. Best of all, the BioSAXS-2000 can be mounted on the open port of a Rigaku rotating anode X-ray generator, taking full advantage of existing infrastructure, or it can be mated to a Rigaku microfocus sealed tube X-ray source. The BioSAXS AUTO configuration incorporates two time-saving features: an Automatic Sample Changer for unattended overnight operation and an Automatic Analysis Pipeline based on the world standard ATSAS package from EMBL Hamburg.
No need to wait for beamtime at a synchrotronThe BioSAXS-2000 is equipped with the new OptiSAXS optic, a doubly focusing multilayer optic whose focus is at the detector. The OptiSAXS provides better than two fold improvement in flux compared to its predecessor resulting in higher brilliance at the sample position and data collection times in the range of minutes. Thus, the BioSAXS-2000 brings a beamline experience to home laboratory SAXS experiments.

Because data collection is faster with the BioSAXS-2000, automated tools for sample mounting, data collection and data analysis become especially important. The BioSAXS AUTO package accomplishes each of those tasks with the Automated Sample Changer (ASC) for automatic sample loading and data collection, and the Automated Analysis Pipeline (AAP) for automatic data processing and analysis.
The EZ Aligner tool allows for safe and remote alignment for VariMax or OptiSAXS optics. As the name implies, the EZ Aligner makes optimization of beam intensities an easy task. Simply set up your pin diode and pinhole, then use the EZ Aligner remote to optimize the beam from a safe place outside the radiation enclosure. Each EZ Aligner remote produces a radio signal strong enough to penetrate enclosure material or from another room. The EZ Aligner kit includes a remote control that communicates to 4 motors attached to optic micrometers to adjust optic rotation and translation.
|BioSAXS Automatic Sample Handling||
The ASC provides unattended sample mounting and data collection for those labs who want to take advantage of the higher throughput capabilities offered by the BioSAXS-2000. The ASC supports samples supplied in 96-well plates or 0.2 mL PCR tube arrays and seamlessly integrates with the hardware and SAXSLab software control package. Solution samples can be foil-sealed to ensure that your samples won’t evaporate prior to data collection. The ASC also includes support for temperature controlled sample storage and for multiple cleaning solutions and cleaning protocols.
|Automatic Data Analysis Pipeline||
The AAP utilizes the industry standard ATSAS package to provide the following automatic analyses for each sample:

Focuses and monochromatizes an X-ray beam for small angle X-ray scattering
Rigaku's OptiSAXS optic is the latest generation of Cofocal Max-Flux® (CMF) optic for the BioSAXS-2000 SAXS system configured with a Rigaku microfocus rotating anode generator. The long length of the OptiSAXS optic allows it to capture more of the X-ray beam from the microfocus generator resulting in higher flux. As a result, the OptiSAXS optic delivers an intense, monochromatic X-ray beam with greater than two-fold higher flux compared to its predecessor.
- Graded, multilayer confocal optic with increased length for maximum beam intensity.
- Double-bounce beam geometry for optimum beam purity
- Designed to achieve maximum performance when coupled with Rigaku microfocus X-ray generators
