TECHNICAL NITROGEN FOR LABORATORIES — economical nitrogen for support tasks in the laboratory
Technical nitrogen for laboratories from REAL GAZ is a practical grade of 99.5% to 99.9% nitrogen meant for the many tasks around an instrument that do not need ultra-pure gas. It is far more economical than analytical grades and still free from oil and visible contamination.
Choosing the correct grade for each task also keeps the cost of high purity nitrogen for the places where it truly counts.
Choosing the correct grade for each task also keeps the cost of high purity nitrogen for the places where it truly counts.
Quality is guided by ISO 8573-1 classes for dryness, ISO 9809 cylinder construction and ISO 17025 record-keeping, for teaching and routine testing laboratories.
A sensible laboratory policy lists which tasks use which grade: technical nitrogen for drying, purging and general inerting, 5.0 for detectors and columns, and 6.0 only where the method demands it. Labelling each line and regulator with the grade it carries avoids accidental mix-ups. We can supply a simple colour-coded tag set to support this practice at no extra complexity.
Technical nitrogen is also useful during method development, when analysts run many exploratory injections or drying cycles and do not want to consume expensive gas. Once the method is fixed, the final validation can then be run with the high purity grade the method specifies. This keeps both quality and budget under control.
Cylinders delivered for this grade are inspected, cleaned externally and labelled with the grade and fill date. Teaching laboratories often like the smaller 10 and 20 litre sizes, which are easier for students and technicians to handle, while research groups choose 50 litre cylinders for fewer changeovers across a busy week.
🏭 Where Technical Nitrogen Are Used
- ⚙️ Sample preparation — Nitrogen blow-down and drying of glassware, filters and extracts;
- 🔬 Autoclave and oven inerting — Ovens and furnaces use technical nitrogen to limit oxidation during heating;
- 🏥 Pressure-driven filtration — Gentle nitrogen pressure drives solvents through columns and membranes;
- 🚀 Teaching demonstrations — Students can safely work with inert gas and cryogenic effects.
