Laboratory Liquid Nitrogen — dependable cold for research, storage and sample preparation
Laboratory Liquid Nitrogen from REAL GAZ is supplied in dewars sized for research groups, hospitals, universities and testing laboratories that need regular, predictable access to −196 °C.
Every delivery is accompanied by a handling sheet and the information required by the receiving department.
Every delivery is accompanied by a handling sheet and the information required by the receiving department.
Deliveries comply with ADR (UN 1977), vessels with EN 13458, and product quality is controlled in line with ISO 17025 and ISO 9001 practices for research customers.
Laboratories often keep two or three dewars in rotation: a 50 litre mobile dewar for daily use, a 25 litre vessel for bench work and a large fixed storage dewar that is topped up weekly. We can agree fixed visit days so that nitrogen is never the bottleneck of an experiment. Customers using automatic filling systems for cryostorage tanks can connect to our supply vessel via phase separators, reducing manual handling and the frequency of lid opening. Training is part of the service: new users receive a short briefing on filling techniques, glove selection, emergency response and correct transport of vessels between floors.
🏭 Where Laboratory Liquid Nitrogen Is Used
- ⚙️ Cryostorage — freezer tanks keep cell lines, tissue, bacteria and enzymes viable for years;
- 🔬 Sample preparation — snap-freezing and cryogenic grinding halt enzymatic activity and make hard tissue or polymers brittle;
- 🏥 Histology and dermatology — frozen sections and cryotherapy equipment depend on controlled supplies of liquid nitrogen;
- 🚀 Instrument cooling — cold traps, detectors and cryostats in spectroscopy, microscopy and vacuum equipment use LN₂ as coolant.
💡 Why Choose REAL GAZ
