Cryogenic Liquid Nitrogen for laboratories — ultra-low temperature performance for scientific work
Scientific work often depends on temperatures that ordinary refrigeration cannot reach, and cryogenic liquid nitrogen for laboratories from REAL GAZ fills that gap. At −196 °C it freezes, embrittles and preserves with remarkable speed.
Laboratory vessels are supplied with the correct neck tubes, lids and pressure devices so that staff can transfer liquid without splashing.

REAL GAZ follows ISO 21029 for transportable insulated vessels, EN 13458 for fixed tanks and ISO 17025 sample-handling expectations, suitable for biology, physics and chemistry departments.
Day-to-day laboratory practice benefits from simple discipline. Pour slowly to limit splashing, use tongs rather than hands for frozen items, and let a warm container cool gradually before filling it. Samples stored in the liquid phase can trap liquid inside sealed vials, so vapour-phase storage is often preferred. Dewars should be inspected for frost patches, which suggest vacuum loss, and reported to us immediately for exchange. For long experiments, a vessel with a low evaporation rate and a monitored level gauge reduces the number of manual checks and keeps the sample environment steady over weekends and holidays.
🏭 Where Cryogenic Liquid Nitrogen Is Used
- ⚙️ Cryo-electron microscopy — grids and holders are plunge-frozen and kept cold in liquid nitrogen throughout transfer and imaging;
- 🔬 Superconductivity studies — researchers cool high-temperature superconductors below their critical temperature in simple dewar setups;
- 🏥 Cell and tissue banking — ampoules are stored in liquid or vapour phase tanks so that viability is preserved for later experiments;
- 🚀 Spectroscopy detectors — germanium and infrared detectors need continuous nitrogen cooling to reduce thermal noise and give clean signals.
💡 Why Choose REAL GAZ
- ✅ Fast, clean cooling — nitrogen leaves no residue and evaporates fully, which protects sensitive samples and instruments;
- 🧪 Suitable dewars — wide-mouth, narrow-mouth and pressurised dewars are available so transfer methods match your protocol;
- 🎯 Staff safety focus — we explain oxygen-deficiency risks in small rooms and recommend suitable alarms and ventilation;
- 🔒 Reliable refill rhythm — deliveries are timed to detector fills, storage-tank top-ups and teaching terms;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- purity checks on the liquid and its vapour;
- visual and vacuum inspection of every dewar;
- cleanliness controls to avoid particulates in sample tanks;
- documented handling instructions with each delivery.
Cylinders and vessels comply with ADR / UN transport rules and relevant EN/ISO standards.
