Liquid Helium Continuous Flow Cryostat
Product Code: ^CFICE

An adaptable modular range of static and dynamic continuous flow cryostats.

Sample holders, temperature range, tails dimensions length and diameter can all be modified to suit our customers needs.

Specification of cryostat shown:

• OVC outer diameter 70 mm
• Sample space diameter 49 mm
• Single shot base temp 1.3K
• Helium consumption < 1.5 l/h
• Continuous flow temp 2.2 K (with > 20 cubic meter/hour pump)

Special Liquid Helium Continuous Flow Cryostat (sample in vacuum)
Product Code: ^CFICE^1K100

Designed initially for neutron facilities, this continuous flow insert has a very low stable base temperature in both single shot and continuous flow modes, the insert operates in a vacuum and can be supplied with its own vapour cooled shields and cryostat or it can parasitise within a cold bore environment. The insert also benefits from a fast sample turn around time and large sample space in vacuum.

Specification of cryostat shown:

• Sample space up to 100mm
• Single shot base temperature <1.2K
• Continuous flow base temperature <1.4K
• Temperature range 1.2K to 300K
• Stability below 10K ±0.1K
• Stability above 10K ±0.5K

A ^CFICE^1K50 50mm diameter version is also available.

Liquid Helium Continuous Flow Optical Cryostat
Product Code: ^OPTIICE^CF

Continuous flow CF of either LN2 or LHe is directed through a heat exchanger which in turn cools the sample either by direct contact with the flow (dynamic) or via exchange gas (static).

Range of windows

Suitable for the following range of spectroscopy techniques:

• Raman
• Infrared
• Visible and ultra-violet spectroscopy
• Photoluminescence
• Photo-conductivity and electro-optical studies

Specification:

• Temperature range 2.2 - 300 K
• Stability ±0.1 K
• Base temperature 1.6 K (single shot)
• Sample turnaround 5 mins
• Continuous flow temp 2.2 K (with > 20 cubic meter/hour pump)

Liquid Nitrogen Continuous Flow Cryostat
Product Code: ^CFICE^N

An adaptable modular range of static and dynamic continuous flow cryostats.
