Rigaku Oxford Diffraction offers the PILATUS3 R 200K as the standard detector for single crystal systems. PILATUS3 R detectors are true photon counting devices that combine the following features to make them the best commercially available detectors for protein crystallography: 
 

the highest sensitivity 

the lowest readout noise 

the fastest readout time 

the lowest point spread function 

fully air-cooled and maintenance free 
 
Whether you’re collecting data for small or weakly diffracting samples or collecting data for S-SAD phasing, a Rigaku Oxford Diffraction system configured with a PILATUS3 R detector ensures the most accurate data collection for your samples. The PILATUS3 R 200K is also ideal for high throughput screening and ligand binding studies, especially when coupled with an ACTOR automatic sample changer. 
 

Why the HPAD detector? 
There are basically four types of detectors currently being used with single crystal diffractometers: HPAD, CCD, CMOS, and IP. The HPAD is the newest technology and is unique in that it is a photon counting detector that directly detects X-ray photons without the intermediate step of converting the photons to light with a phosphor. 
The HPAD detector allows for shutterless data collection due to the extremely fast readout. This capability eliminates errors in the diffraction data originating from shutter timing and goniometer stop/starts, which are invariably associated with traditional data collection, and minimizes data collection time. In addition, the extremely low noise characteristics means that you can count poorly diffracting samples for a long period of time without swamping the signal with electronic noise. The combination of these features means that you will collect better data faster.
