Cryostream Compact

The open-flow nitrogen gas cooler optimised for capillary samples.

The Cryostream Compact is a version of the popular 800 series Cryostream, which has been optimised for use with powder samples in capillaries. The system incorporates a shortened nozzle to allow the Cryostream nozzle to be mounted coaxially with the capillary, thus mitigating the risk of ice formation.

All Cryostream Compact systems offer the "Plus" range of temperatures, so 80 - 500 Kelvin may be achieved. The 800 series controller boasts a touch screen and optional web-based control and monitoring service. The space-saving 800 series coldhead now integrates the shield gas feed, offering more uniform integration on all commercially available X-ray equipment. 

The Cryostream now features an integrated Auto Refill system, allowing users to monitor, control and automatically refill their Cryostream Dewar from the 800 series Controller

Features
  • Shortened nozzle and transfer line options for integration with all XRD cabinets

  • 800 series controller with touch screen and one-touch start, USB and Ethernet connectivity

  • Integrated Autofill system as an option.

  • Best available temperature range of 80- 500 K as standard

  • Proven stability in excess of 0.1 K

Mode of operation

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. This gas then flows outward along one path of the heat exchanger, through the temperature and flow controller, to arrive at the pump.This gas flows back into the Cryostream coldhead where it is re-cooled along the second path of the heat exchanger. 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.
