The Cryostream 800
Note: The 800 series is no longer available.
Thirty years after the invention of the first Cryostream Cooler, we continue to lead the way with the Cryostream 800 series.
Reliable, easy to use and with a low cost of ownership, the space-saving 800 series coldhead now integrates the shield gas feed, offering more uniform integration on all commercially available X-ray equipment.
All of our open flow nitrogen devices are available as a Plus version too, offering temperatures up to 500 K. Together with variable and controlled ramp rates, high stability of 0.1 K, and remote monitoring and control, our open flow devices meet the needs of every single crystal diffraction lab.
It also features an optional Auto Refill system, so you can monitor, control and automatically refill your CryostreamDewar from the 800 series Controller. In addition, the space-saving 80o series coldhead integrates the shield gas feed, giving you more uniform integration on all commercially available X-ray equipment.
Easy to use, reliable and cost effective.
The pump is responsible for the gas flow from an unpressurised Dewar, through the flexible vacuum insulated transfer line, into the Cryostream coldhead. The liquid nitrogen passes through a heater, which evaporates most of the liquid into gas. The gas temperature is regulated by a heater and sensor before entering the nozzle of the Cryostream, flowing along the isothermal nozzle and out over the sample.
The temperature indicated on the Controller is a mapped temperature for the crystal position. The default Cryostream gas flow rate is 5 L /minute, which equates to roughly 0.6 L of liquid nitrogen per hour. This means that a 60 litre Dewar will last for up to 4 days so can easily be run over a weekend without refilling. Turbo mode gives an increased flow rate of 10 L/minute if required.
