Nitrogen jet gives increased temperature range of 90-490K for X-ray crystallography, giving greater freedom in experimental design and more control over sample management
From proteomics to materials characterisation, crystallographers can now investigate molecular structures across an increased range of temperatures (90-490K) using a single piece of equipment, the new Cryojet HT nitrogen jet from Oxford Instruments Superconductivity.
With fast cool-down to base temperature and excellent temperature stability, the Cryojet HT provides the temperature environment needed for sample management in detailed X-ray crystallography studies.
The Cryojet HT contains no moving parts.
As a result, the system has minimal maintenance requirements and is very quiet during operation.
The lack of pumps and compressors also means that the system footprint is kept to a minimum, saving valuable laboratory space. The system is simple to use, with temperature and gas flow settings easy to adjust using the Cryojet electronic controller unit.
Long-term system monitoring is also easy, thanks to the inclusion of ObjectBench software in the control unit.
This enables users to control system settings remotely via computer. The storage dewar is at atmospheric pressure permitting liquid nitrogen refills during use.
Together with the system's high level of stability (+/-0.1K), this means that the Cryojet HT is an excellent partner for long-term cryocrystallography.
In addition to the range of temperatures that can be achieved, the tapered design of the Cryojet nozzle gives crystallographers the precision needed even for the highest resolution work.
The nozzle can be brought to within a few millimetres of the crystal without interfering with the collimator or the diffracted beam.
Tilt adjustment and XYZ translation stages allow the jet nozzle to be precisely aligned in order to achieve the optimum experimental geometry with commercially available X-ray diffractometers and synchrotrons.
In addition, the shield flow of gas ensures that the nozzle and the sample do not become iced up.
Using the Cryojet HT, crystallographers have greater freedom in experimental design and more control over sample management.
