Helium cooled continuous flow cryostat enabling optical spectroscopy experiments below 4K.
Enables quick sample change as sample is in exchange gas.

• 20 mm diameter sample space (sample cooled in a static exchange gas)
• Five optical access ports (4 radial and 1 axial) for demountable windows. Fitted with blanks as standard
• Optical access f/1 in radial directions
• Temperature range
• 3.4 -300 K (with GF4 pump)
• 2.3-300 K (with EPS40 pump)
• Temperature stability +/-0.1 K using an ITC controller (measured over a 10 min period)
• Outer tail dimension 80 mm (across the flats)
• Heat exchanger fitted with heater and rhodium iron temperature sensor
• Cool down time from room temperature 25 min
• Cool down consumption 1.5 L
• Liquid helium consumption rate at 4.2 K, < 550 cc/hr
• Sample change time around 5 min (sample can be changed with the cryostat cold)
• System may also be run with liquid nitrogen, temperature range 77 ��? 300 K
• Copy of Oxford Instruments Safety Matters
• Operators manual
• All specifications refer to the standard system using an LLT transfer tube
• Notes:
• System will be tested with the ordered pump(s) only. In the case that no pumps are ordered then the system will be tested with a GF4 pump only.
• OINS can only guarantee temperatures below 3.0K if a 30 point calibrated RhFe sensor is purchased and fitted.
