With an extensive range of field-proven applications and a worldwide installation base, SuperTran represents the state-of-the-art in continuous flow cryostat design. Using liquid helium (LHe) or liquid nitrogen (LN2), most of the systems provide fast (15 min or less to 4.2 K with LHe) cooldown, a <2 K to 325 K total operating range, and precise temperature control capability in an economical and easy-to-use package.
All systems consist of a cold finger, radiation shield, sample holder, lightweight aluminum vacuum shroud, electrical feedthrough ports, and a high-efficiency flexible 6 ft cryogen transfer line. SuperTran cryostats can be operated in any orientation with only minor variations in efficiencies. Sample temperatures are varied by means of a heater attached to the cold finger. The sample mount and all standard Lake Shore sample holders have provisions for thermometry which, in conjunction with an optional temperature controller, allow precise control over sample temperature.
