Rigaku Micromax-007 HF 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 (8×10 10 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 8×10 10 X-rays/mm²/sec Proven productivity across the largest installed base 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. With a brilliant 8×10 10 X-rays/mm²/sec beam coming from the smallest possible focal spot (70 μm × 70 μm), 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 Osmic™ VariMax™ optics, flux can be traded for lower divergence to deliver superior resolving power. 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. 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. Features of the MicroMax-007 HF include: Smallest focal spot size of any rotating anode generator (70 μm x 70 μm) 1.2 kW power in a small beam provides greater flux density and less background for tiny crystals Extended anode and filament lifetimes Unique pre-aligned and pre-crystallized filament cartridges minimize maintenance Moveable anode assembly accommodates any hardware configuration Choice of anode materials: Cu, Mo, Ag, and Cr Optimum performance achieved when coupled with Osmic™ VariMax™ optics The X-ray generator of the HighFlux HomeLab™ A high flux option for Rigaku small molecule and SAXS systems The MicroMax-007 HF sets the standard of excellence for rotating anode generator performance, reliability and uptime.
