LT4 Helium Flow Cryostat
The LT4-DMX-1AL is our lowest cost liquid flow cryostat for optical and electrical experiments.
The LT4 works with either liquid helium or liquid nitrogen. The LT4 utilizes a standard transfer line and cold tip. If you need lower vibrations, take a look at the high performance LT3-WMX-1.
