Single-Cystal X-ray Diffractometer
The XtaLAB PRO series is a high-performance family of single crystal diffractometers designed for applications from small molecules to macromolecules. Central to its design is the Hybrid Pixel Array Detector (HPAD), specifically the PILATUS 200K, which enables direct X-ray photon counting without phosphor conversion, achieving near-zero noise, high dynamic range, and ultra-fast readout. This allows shutterless data collection, eliminating shutter delays and overload rescans, significantly reducing experiment time compared to CCD or CMOS systems. The HPAD’s "top-hat" point spread function excels in resolving large unit cells and capturing weak reflections from poorly diffracting crystals. The system supports multiple X-ray source configurations: microfocus sealed tubes (Cu/Mo), sealed tubes with SHINE optics, or high-flux rotating anodes such as the MicroMax-007 HF and FR-X for challenging samples. A kappa goniometer and a large, adaptable enclosure allow convenient access and support in-situ mounting of air- and temperature-sensitive samples. By combining speed, flexibility, and high data quality, the XtaLAB PRO offers performance approaching synchrotron beamline standards for diverse crystallographic needs.
Features
