Precision Liquid Gas Cylinders — accurately filled cryogenic vessels for exacting processes
Precision Liquid Gas Cylinders are cryogenic vessels where the quantity and quality of the liquid are controlled tightly, not just approximately.
REAL GAZ fills them on calibrated scales, records the net weight and checks purity so that dosing systems and sensitive instruments receive predictable gas.

Weighing equipment is calibrated against reference masses, vessels meet ISO 21029-1, and analysis follows ISO 17025 practice within a quality system aligned to ISO 9001 for repeatable results.
In sensitive processes the cryogen is part of the measurement chain, so small variations can produce visible effects. When a liquid nitrogen doser feeds a canning line, a swing of a few tenths of a bar changes the dose and therefore the can pressure. When a trap cools a detector, unstable temperature produces baseline noise. REAL GAZ addresses this by setting pressure building circuits to the required level, checking relief valve settings and recording actual vessel pressure at delivery. We can also supply phase separators and filters to ensure that mostly liquid reaches the dosing head, reducing flicker and ice formation in nozzles.
🏭 Where Precision Liquid Cylinders Are Used
- 🧪 Cryogenic dosing — liquid nitrogen dosers need stable supply pressure to meter into containers precisely;
- 🔬 Calibration labs — stable cryogenic baths and traps depend on consistent fill levels;
- 🧬 Pharma freeze drying — controlled cooling cycles use liquid nitrogen with low moisture content;
- 🏭 Semiconductor tools — chillers and traps use predictable cryogen quantities to hold temperature profiles.
