Typical applications:

ST-300/T specifications

Temperature range	~2 K to 500 K (700 K optional)
Initial cooldown time	15 min
Nominal temperature stability (with controller)	50 mK or less
Orientation	Any position (with increased helium consumption)
System weight (without transfer line)	~10 lb (4.6 kg)
Cryogen consumption on cooldown	0.4 L LHe (325 K to 4.2 K) 0.1 L LN₂ (325 K to 77 K)
