MicroMax-007 HF

Microfocus Rotating Anode X-ray Generator

Protein crystallography, small molecule crystallography, SAXS, micro-diffraction, phase contrast imaging

The MicroMax™ 007 HF is the most widely used home lab X-ray source for protein crystallography and a popular source for small molecule crystallographers who need the additional flux of a rotating anode generator. 

MicroMax-007 HF Overview

The original MicroMax-007 introduced the world to the concept of a sub-100 micron focal spot size along the increased brilliance that can be more effectively used to illuminate small crystals. The current HF version increases the power loading by 50% over the original model providing an X-ray source that rivals second generation synchrotron sources - but with better beam stability and, of course, easy access.

Engineered for productivity

Productivity can be measured in many ways but the up-time of a system is perhaps one of the most important issues. Unlike competing products, the MicroMax-007 HF was designed with up-time in mind. Filament changes are quick and painless with Rigaku microfocus generators. Superior Rigaku engineering has reduced this service headache to a 45 minute maintenance routine of simply changing a cartridge.

Designed for flexibility

Featuring a robust 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.

Functionality redefined

Perhaps the best way to define the functionality of the MicroMax 007 HF is to quote one of our satisfied customers:

“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.”
