Precision Liquid Helium — tightly controlled quality for sensitive instruments
Precision Liquid Helium from REAL GAZ is selected for instruments where small contamination or temperature drift ruins a measurement. Typical users operate SQUID magnetometers, scanning probe microscopes and quantum computing prototypes.
We pair tight impurity control with careful dewar preparation so the helium that arrives is the helium that reaches your cold space.

Quality control is guided by ISO 6142, ISO 6143 and ISO 17025 practice for gas analysis, with transport to ADR.
Precision users tend to ask three questions: what is in the helium, how consistent is it from lot to lot, and how was the container treated? We answer each in writing. Impurities such as neon, hydrogen and oxygen are reported, container history is recorded, and repeat orders are drawn from the same production source whenever possible, which keeps your baselines comparable across months of data.
Grade names vary between producers, so we describe helium by measurable impurity limits rather than marketing labels. Customers can request analysis for specific components, for example neon below a chosen threshold, and we confirm in advance whether the request is achievable. This honesty avoids surprises once the cryostat is already cold.
🏭 Where Liquid Helium Is Used
- ⚛️ Quantum computing — Dilution refrigerator pre-cooling and test setups demand clean helium that does not freeze out in fine tubing;
- 🔬 SQUID magnetometry — Highly sensitive magnetic measurements need a stable and quiet bath temperature;
- 🧫 Scanning probe microscopy — Atomic-scale imaging at low temperature depends on mechanical and thermal stability;
- 📡 Metrology — National and industrial measurement laboratories use helium cryostats for reference standards.
