Cryostream 1000

Industry Standard Cooling for XRD in Crystallography and Spectroscopy

A Cryostream coldhead is mounted to a Varibeam stand, with cables and transfer lines neatly tied and extending from the back.

The Cryostream 1000 is the universal standard for open-flow sample cooling and the default choice in most XRD cabinets. It provides a stable, precisely controlled nitrogen cold stream across a wide temperature range of 80–500 K. A protective laminar flow of dry air shields the stream from ambient moisture, preventing ice formation while enabling reliable cooling of both organic and inorganic samples.

By reducing radiation damage, the Cryostream ensures accurate and reproducible diffraction studies, supporting applications from protein structure determination to evaluating the staThe Cryostream XRD is the universal standard for open-flow sample cooling and the default choice in most XRD cabinets. It delivers a highly stable cold-stream of nitrogen gas onto the sample stage, enabling precise temperature control of the sample environment from 80–500 Kelvin.bility and morphology of pharmaceutical crystals.

* At temperatures below 90 K, LN consumption may increase to 1.2 L/hour.

Turbo mode gives an increased flow rate of 10 L/min.

When using 1.5 m transfer line, 25 mins if using 3 meter transfer line.

Options

Configure the Cryostream to meet the needs of your research. These options support a broad range of applications, and enable integration into a variety of experimental setups. Many of these began as bespoke solutions for specific customers, and we remain committed to ensuring that nothing stands in the way of our customers advancing their science.

Wide Nozzle

The Wide Nozzle enables stable cooling of larger samples, improves compatibility with mounted or embedded specimens, and can reduce X-ray beam shadowing by increasing the working distance between the nozzle and sample.

Cryostream Plus

Cryostream Plus extends the operating temperature range up to 500 K, enabling precise and reproducible heating of samples above ambient temperature. This expanded range supports a wider variety of experiments, from catalyst and semiconductor studies to advanced materials research.

Compact Nozzle

The compact nozzle reduces the overall length of the coldhead by 134 mm, making it ideal for installations where space is limited. Its shortened design also supports applications requiring horizontal sample access or constrained experimental geometries.

Longer Transfer Line

The longer transfer line extends the distance between the Cryostream and the dewar, providing greater flexibility when integrating the system into large X-ray diffraction cabinets or laboratory environments.

Accessories

Cryostreams consist of a Gas Supply Module (GSM), a Coldhead, and a custom 60L Dewar. Alongside this configuration, users have the option to enhance their setup with additional accessories.

Varibeam

This coldhead mount features fine-adjustment controls that provide smooth translational movement along the X, Y, and Z axes, ensuring precise and repeatable alignment with the sample for every experiment.

Autofill

Designed for use with the 60 L Dewar, the Autofill automatically monitors liquid nitrogen levels and refills the local dewar from a supply dewar as required. This enables extended, uninterrupted operation of the Cryostream while eliminating the need for manual refilling.
