Laboratory R-404A Gas Cylinder

Laboratory R-404A Gas Cylinder — controlled low-temperature refrigerant for test work

A Laboratory R-404A Gas Cylinder from REAL GAZ holds the HFC blend of R-125, R-143a and R-134a used in low-temperature refrigeration research and equipment testing.
Each cylinder is filled from a verified batch, so test results are not distorted by moisture, air or off-specification composition.

REAL GAZ supplies this refrigerant in line with ISO 817 designation, AHRI 700 purity guidance and EN 378 safety practice, for laboratory and development departments.

🏭 Where R-404A Laboratory Cylinders Are Used

⚙️ Compressor test benches — qualifying scroll and semi-hermetic compressors for freezer duty at evaporating temperatures near -35 °C;
🔬 Environmental chambers — charging low-temperature test cabinets used for stability and shelf-life studies;
🏥 Teaching laboratories — training refrigeration engineers in recovery, leak checking and charging on small systems;
🚀 Component research — measuring expansion valve and evaporator performance with a known, documented charge.

💡 Why Choose REAL GAZ

✅ Documented composition — the blend is held close to its nominal 44/52/4 mass ratio so repeat tests stay comparable;
🧪 Low moisture — dry filling protects POE oil and the sensitive internals of test rigs;
🎯 Practical sizes — small refillable and disposable cylinders suit bench work, with larger vessels for chamber fleets;
🔒 Traceable batches — each cylinder carries a batch number for audit trails in accredited laboratories.
📄 Certificate of Analysis (CoA) — supplied with every order.

🔬 Quality Control & Safety

liquid-phase filling to hold the blend composition;
vacuum drying and moisture checks before charging;
non-condensable gas and acidity analysis per batch;
valve leak testing and weight verification.

Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.

📘 Technical and Handling Notes

R-404A has an ODP of zero and a high GWP of about 3922, so laboratories should plan recovery and reclaim of every charge. The blend is near-azeotropic with a very small glide, which makes it convenient for repeatable measurements. Liquid must be withdrawn from the cylinder, and transfer hoses should be rated for the vapour pressure at room temperature, roughly 12 bar at 20 °C. Store upright, away from heat, with the valve cap fitted.

Choosing the right cylinder size matters in a laboratory. A small 5 kg or 10 kg vessel is easy to weigh on a bench balance, which lets researchers confirm the exact charge added to a test rig and calculate refrigerant mass flow with confidence. Larger vessels suit chamber fleets that are recharged regularly. Because R-404A is being phased down under the F-gas Regulation, many laboratories also study lower-GWP alternatives such as R-448A or R-449A against it, and a reliable R-404A baseline cylinder makes those comparisons meaningful. We can discuss a matched supply for both baseline and comparison refrigerants. Ask us for a short data sheet listing the blend, GWP, pressure at 20 °C and storage advice.
