XtaLAB mini II

Benchtop small molecule structure determination

The Rigaku XtaLAB mini II benchtop X-ray crystallography system is a compact single crystal X-ray diffractometer designed to produce publication-quality 3D structures. The perfect addition to any synthetic chemistry laboratory, the XtaLAB mini II will enhance research productivity by offering affordable structure analysis capability without the necessity of relying on a departmental facility. With the XtaLAB mini II, you no longer have to wait in line to determine your structures. Instead your research group can rapidly analyze new compounds as they are synthesized in the lab.

Teach diffraction through hands-on experience

In many universities, the departmental X-ray diffractometer is considered off limits to students because of fear that the instrument might be damaged by inexperienced users. The XtaLAB mini II provides the opportunity for students to learn single crystal analysis by actually using a diffractometer. This is not a black box instrument. Rather, the important step of mounting a crystal on the goniometer and physically centering the crystal in the position of the X-ray beam, ensures that students learn the importance of mounting techniques and crystal selection. The simple design of the XtaLAB mini II minimizes the danger of students damaging the system.

Reduced size does not mean reduced data quality

The Rigaku XtaLAB mini II is a research grade chemical crystallography instrument that sits on the benchtop. No data quality compromises, no extended collection times. Results delivered are unambiguous. X-ray tube lifetime is extended by running at 600 W. To compensate for running at a lower power, a SHINE optic (special curved monochromator) is utilized to produce usable X-ray flux comparable to a standard X-ray system.
Dedicated to producing publication quality structures
The chief design requirement when creating the XtaLAB mini II was that the structures produced would be publishable in the most demanding scientific journals. The HPC detector is positioned so that the maximum 2θ value is well outside of the Acta Cryst. requirements. The software provides all the tools you need to generate publication quality data that can be used to determine 3D structures from a variety of structure analysis packages.

CrysAlisPro — User-inspired software for superior data quality

Rigaku Oxford Diffraction systems come complete with CrysAlisPro, our user-inspired data collection and data processing software for small molecule and protein crystallography. Designed around an easy-to-use graphical user interface, CrysAlisPro can be operated under fully automatic, semi-automatic or manual control.

Automatic Crystal Screening

At the heart of CrysAlisPro are the automatic crystal screening, data collection and strategy modules. For a typical crystal, a short pre-experiment lasting less than five minutes is recorded to evaluate crystal quality. From the first frame, CrysAlisPro automatically evaluates the crystal quality and provides the user with information regarding the unit cell, intensity estimation by resolution range and suggested frame exposure times for the full data collection. Additionally, CellCheckCSD (developed with the Cambridge Crystallographic Data Center) helps prevent the collection of known structures by automatically screening the CSD for unit cell matches.

Fastest Strategy Software

CrysAlisPro's sophisticated strategy software automatically calculates the optimal conditions for fast, high quality, complete data collection. All strategies are rapidly calculated based on the specific crystal orientation and unit cell. The user has complete control to optimize the strategy for a wide variety of targets including multiplicity, time and resolution. Strategy calculations are extremely fast and efficient, allowing the user to quickly adapt the data collection conditions for a variety of experiment types, with both Mo and Cu radiation.

Automatic and Concurrent Data Reduction

Data reduction and processing initialize automatically with the start of data collection and employ intelligent routines which tune the parameters to give the best data quality. Processed data are accompanied by real time on-screen feedback of data quality and completeness. CrysAlisPro is programmed for multi-core data processing, meaning rapid results even from the largest data sets.

A Full Complement of Crystallographic Tools
In addition to automatic routines, CrysAlisPro includes a very comprehensive and highly effective range of tools and functions for dealing with non-standard and problematic data. These tools are available through the GUI or from a command line interface, and include:
  • Advanced unit cell finding
  • EwaldPro — Reciprocal lattice viewer
  • Twin data processing
  • Incommensurate data processing
  • Automated high pressure data collection and reduction
  • Face-indexing — with automated shape generation
  • Multi-temperature experiments
  • Powder data collection and processing
  • Precession image generation
  • Axial photos

Software Compatibility

Use CrysAlisPro to import and process frames from synchrotrons and other detector formats. Data is automatically output in HKLF format and quick links interface directly to Olex2, CRYSTALS, WinGX and Jana (for use of SHELX, SIR, Superflip and other programs, where installed). Data files are also easily exported for use in third party data reduction packages including MOSFLM, DENZO and XDS.

AutoChem is the ultimate productivity tool for chemical crystallography, offering fast, fully automatic structure solution and refinement during data collection. Developed exclusively for Rigaku Oxford Diffraction by the authors of Olex2 (Durham University and OlexSys), AutoChem builds upon the success of our original AutoChem software. Seamlessly integrated as an optional plug-in for CrysAlisPro, AutoChem offers an advanced approach for automatic structure determination, with an even higher rate of success.

AutoChem can work with or without a chemical formula, intelligently using multiple solution programs and typically requiring only partial completeness to solve routine structures. In more difficult cases, AutoChem will make attempts in multiple space groups. A number of refinement options are available; atoms are modeled anisotropically where the data supports it and hydrogen atoms are included in calculated geometric positions. The structure is then re-labeled and refined to completion before a final structure report is generated.

CrysAlisPro displays the structure and key refinement parameters, and provides a link to a full Rigaku Oxford Diffraction’s edition of Olex2 — complete with AutoChem plug-in — which can be launched at any time. Here the user can review all aspects of the refinement, step back to any stage of the process and apply changes as necessary.

The 800 Series Cryostream is the most robust, efficient and user-friendly liquid nitrogen based low temperature system available today. Specific features include a superior laminar flow system, meaning virtually zero risk of icing, extremely quiet running and a fast-start system resulting in a cool-down time to 100K of just 20 minutes.
