The Helijet by Agilent Technologies is specifically designed for cryo-crystallography experiments requiring temperatures in the range of 75-15 Kelvin. It is developed for use with Agilent Technologies' Xcalibur, Gemini, and SuperNova diffractometers, and its compact construction is ideal for CCD diffractometers. The unique design of the Helijet allows for complete freedom of movement of a Kappa goniometer and unobscured optical access to the biological macromolecular or small molecule crystal without the need for crystal shielding. The Helijet provides an efficient cold stream up to 5 mm from the nozzle tip with a very uniform temperature distribution within the cold stream. To prevent ice formation, the Helijet utilizes shield gas technology. It has a patented design that minimizes helium consumption to less than 2 liters per hour and achieves a base temperature of less than 10 K.
The Agilent Technologies Helijet is an open flow helium jet specifically designed for cryo-crystallography experiments requiring temperatures between 75 K and 15 K. It features a compact construction ideal for use with CCD diffractometers, such as the Xcalibur, Gemini, and SuperNova series.
The device utilizes shield gas technology to prevent ice formation on the nozzle or crystal sample while providing an efficient cold stream up to 5 mm from the tip. Its unique design eliminates the need for crystal shielding, allowing complete freedom of movement for a Kappa goniometer.
