MicroMax™-007 HF microfocus X-ray generator
As the most popular microfocus rotating anode X-ray source for structural
biology, the Rigaku MicroMax-007 HF provides brilliance equaling the very
best competitive products (8 × 1010 X-rays/mm²/sec) with a smaller focal spot
and while providing lower cost-of-ownership (COO) and higher productivity.
High uptimes and "designed-in" maintainability differentiate the
MicroMax-007 HF from the competition. Ideal for rapid screening of samples
and for collection of the highest quality data for in-house structure
determination, the MicroMax-007 HF provides the flux you need, where you
need it: on your crystal.
- Designed for small and poorly diffracting crystals
- Brilliant flux intensity of 8 × 1010 X-rays/mm²/sec
- Proven productivity across the largest installed base

We recently replaced our optics-equipped 5 kW rotating anode with a Rigaku Micromax-007 HF and VariMax HF optics. We continue to use our original IP detector. Having been involved in the purchase of several generation of generator I'm used to the assurances of "This is almost as powerful as a synchrotron beam line." This time is unusual in that the promise has been fulfilled. We have seen exposure times go from 25-30 minutes to 30 seconds, and visible diffraction from crystals we never previously expected to diffract at home. The new generator has made a major difference in our ability to investigate macromolecular crystallographic problems. |

Upgrade now to a proven "state-of-the art" source
Commercial microfocus sources, suitable for protein crystallography, first became available early in this decade with the advent of the original Rigaku MicroMax-007 microfocus rotating anode generator. Introduced in 2004, the more powerful (1.2 kW) MicroMax-007 HF incorporates three patented design enhancements. The system was engineered to be the perfect upgrade path from older generations of large focal spot generators. The MicroMax-007 family of generators continues to be the most popular microfocus rotating anode X-ray source available today.
Power and flexibility equals superior performance
With a brilliant 8 × 1010 X-rays/mm²/sec beam coming from the smallest possible focal spot (70 μm diameter circle), the MicroMax-007 HF delivers performance that is beneficial for all aspects of in-house crystallographic research. The most challenging projects can now be performed in the home laboratory: screen crystals where no diffraction was seen on a standard system, collect full data sets on samples where only low resolution reflections would normally be observed, and solve previously intractable structures. When equipped with high performance adjustable VariMax™ optics, flux can be traded for lower divergence to deliver superior resolving power.
Engineered for reliability
The real day-to-day productivity of a system is dependant on its operability, maintainability and whether or not human factors are at the core of the design. Featuring a unique direct-drive anode, the MicroMax-007 HF compact tower assembly contains both the vacuum chamber and turbo-molecular pump for fast pump downs. Conveniently mounted on the generator tabletop, the tower may be easily moved for integration with various optics, goniometers and detectors. Unlike competing products, the MicroMax-007 HF was designed for lower real cost-of-ownership. For example, filament changes are not an "all day affair" with Rigaku microfocus generators. Superior Rigaku engineering has reduced this service headache to a "do-it-yourself" 45 minute maintenance routine of simply changing a cartridge.
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 16% of all submitted
structures for 2006, the latest year of complete data. Of structures solved
with home lab sources that year, 88% 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.
