Liquid Nitrogen Cryostat System

The Liquid Nitrogen Cryostat System developed by Vectomag is a cost-effective and highly versatile low-temperature platform based on the steady-state bubble principle for precise temperature control.

By adjusting the cone-shaped gas plug clearance, the system stabilizes the boiling condition at the gas-liquid interface, effectively controlling heat leakage at a steady rate. Through the temperature controller, the sample stage temperature can be rapidly changed and accurately maintained at the desired value.

It is ideal for Hall effect, magnetoresistance, superconductivity, temperature-dependent electrical and optical experiments, magneto-optical measurements, and student demonstrations.

Applications extend to vacuum systems, magnetic fields, microscopy, spectroscopy, and low-temperature imaging.
