Helium-3 (He-3) – Stable Isotope
He-3 is a non-radioactive, rare, stable isotope of helium in gaseous form, widely used in advanced scientific and industrial applications.

Its exceptional purity and isotopic enrichment make it ideal for demanding research, detection, and quantum technology applications.

Our supply ensures ultra-high purity and consistent isotopic quality.

Applications:

• Quantum computing and superconducting systems (dilution refrigeration)

• Neutron detection and homeland security instrumentation

• Cryogenics and ultra-low temperature research

• Magnetic Resonance Imaging (MRI) using hyperpolarized gas

• Fundamental physics and spin-polarized target experiments
