Description
Technical Specs
Extended Info & Downloads
The OptistatCF-V2 is a helium continuous flow cryostat with sample in vacuum.
> Heater and calibrated 3 point rhodium iron sensor fitted to heat exchanger
Temperature range
3.2 - 500 K (with GF4 pump)
2.2 - 500 K (with EPS40 pump)
Temperature stability <0.1 K using an ITC controller (measured over a 10 min period)
Cool down time from room temperature 10 min
Cool down consumption <1.3 L/hr
Liquid helium consumption of COLDUNIT <450 cc/hr at 4.2 K
System may also be run with liquid nitrogen, temperature range 77 to 500 K
Optical access f/0.9 in radial directions
Outer tail dimension 70 mm (across the flats)
Note 2: All specifications refer to the standard system using a standard length LLT transfer tube and a GF4 pump
Notes:
1. 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.
2. OINS can only guarantee the performance below 3.0K if a calibrated 30 point RhFe sensor is purchased and fitted.
