The Cryostream 800 - stable and effective cooling for single crystal and powder samples
Note: Due to the release of the Cryostream 1000, 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.
Features & Tech Specs
The 800 series is the fourth generation Cryostream, and is built on an extensive platform of expertise and experience gained since the first model was built in the Clarendon Laboratory, University of Oxford. The high-level of features include:
- 800 series controller with touch screen and one-touch start, USB and Ethernet connectivity
- Autofill system.
- Best available temperature range of 80- 400K for the 800 standard, and 80- 500 K for 800 Plus.
- Proven stability in excess of 0.1 K.
- Low & constant LN2 consumption means a 60 litre Dewar can last up to 4 days.
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.

Innovative coolers for the global scientific community
We have a range of systems available that do not use liquid nitrogen. Our Cobra uses a GM cooler to provide base temperatures of 80 K and the new Smartstream is a clever compact Cooler, delivering 170 K from a single unit without cooling water or complex service.
