High Purity Helium Tank 99.99% (19g / 106 liters)

Description

When purity matters, there’s no room for compromise. This compact, Italian-made helium tank delivers 99.99% pure compressed helium — ready to use straight out of the box for precision applications, balloon inflation, leak detection, and more. At just 19g with 103+ liters of gas, it’s the portable, high-performance solution growers and lab users reach for when they need clean, reliable helium without the hassle of a full-size cylinder.

Why the High Purity Helium Tank 99.99%

Most consumer-grade helium tanks are blended or diluted — fine for party balloons, but not for applications where gas purity actually matters. This tank is filled with 99.99% pure helium (He), manufactured and filled in Italy to exacting standards. The M11 x 1.0 thread is compatible with our precision regulators and valve dispensers, giving you controlled, consistent output at 80 PSI. Whether you’re inflating latex balloons for maximum float time or using helium in a technical setting, this tank delivers the quality you need in a form factor you can actually work with.

Available in three configurations — Tank Only, Tank with Valve Dispenser, and Tank with Regulator — so you can match the setup to your exact use case without paying for hardware you don’t need.

Key Benefits

• 99.99% Purity: Ultra-high purity helium suitable for precision, scientific, and specialty applications — not just party use.
• Made in Italy: Manufactured and filled to European quality standards for consistent performance and safety compliance.
• Compact & Portable: 19g tank is easy to store, transport, and handle — no heavy cylinders or special equipment required.
• High Capacity: 103+ liters / 3.76 cubic feet of gas at 1,595 PSI — delivers ~31.5 seconds of continuous flow at 80 PSI.
• Flexible Configurations: Choose Tank Only, or add a Valve Dispenser or Regulator for precise, adjustable output via 1/4″ brass barb.
• Non-Refillable / Recyclable: Fully empty the tank at end of use and recycle — no deposit, no return logistics.

Use Cases

• Balloon Inflation (Events & Retail): Inflate latex or foil balloons for parties, retail displays, or events — use HiFloat or polyvinyl alcohol barrier for maximum float time with latex.
• Leak Detection: Use as a tracer gas to identify leaks in sealed systems, HVAC lines, or plumbing — helium’s small atomic size makes it ideal for finding micro-leaks.
• Laboratory & Research Use: Suitable for controlled environments requiring a high-purity inert gas for purging, blanketing, or carrier gas applications.
• Hydroponic & Indoor Growing Labs: Use in controlled atmosphere testing or equipment calibration where an inert, non-reactive gas is required.
• Specialty Gas Applications: Ideal for any application requiring a portable, clean, non-flammable compressed gas with a known purity level.
• Emergency Backup Supply: Keep a tank on hand as a backup for operations that rely on helium and can’t afford downtime waiting on cylinder delivery.

Directions for Use

• Select your configuration: Tank Only, Tank with Valve Dispenser, or Tank with Regulator.
• Attach your regulator or valve dispenser to the M11 x 1.0 tank thread (hand-tight, then snug — do not overtighten).
• Connect your output hose or balloon nozzle to the 1/4″ brass barb output.
• Open the valve slowly and control flow via the regulator needle valve (if using regulator) or pushpin valve (if using valve dispenser).
• For latex balloons: apply HiFloat or a polyvinyl alcohol barrier inside the balloon before inflation to slow helium permeation and extend float time.
• When empty, fully depressurize the tank and recycle per local regulations. Do not puncture or incinerate.

What Growers Are Saying

“I’ve tried cheaper helium tanks before and always had issues with purity affecting my leak tests. This one is consistent every time — the regulator setup makes it easy to dial in exactly what I need.”

— Marcus T., Hydroponic Lab Operator

“Compact, ships fast, and the 99.99% purity is exactly what I needed for my controlled atmosphere work. The M11 thread fits perfectly with the regulator I ordered. Will be reordering.”

— Diane R., Indoor Grower & Researcher

“Used this for a large balloon installation at our dispensary grand opening. Filled over 40 balloons with one tank and still had gas left. Quality is noticeably better than the big-box store tanks.”

— Jordan K., Retail Store Owner

Frequently Asked Questions

Q: Is this tank refillable?
A: No — this is a non-refillable tank. Once empty, fully depressurize and recycle per your local regulations. The compact size and low cost make it easy to simply reorder when needed.

Q: What’s the difference between the Valve Dispenser and the Regulator?
A: The Valve Dispenser is a simple pushpin-style on/off valve with a 1/4″ brass barb output — great for balloon inflation. The Regulator is adjustable via a needle valve, regulated to 80 PSI, and includes gauges (reads in BAR) — better for precision or technical applications.

Q: How many balloons will this tank fill?
A: Output depends on balloon size. The tank delivers ~31.5 seconds of continuous flow at 80 PSI. For standard 11″ latex balloons, expect to fill approximately 30–50 balloons depending on inflation level.

Q: Why does purity matter for balloon inflation?
A: Higher purity helium has fewer impurities that can degrade latex and reduce float time. For best results with latex balloons, use a HiFloat or polyvinyl alcohol barrier — helium atoms are extremely small and will permeate through latex faster than air.

Q: Is this safe to use indoors?
A: Helium is non-toxic and non-flammable (Transport Hazard Class 2.2 — Non-Flammable Gas). Use in a well-ventilated area. Do not inhale directly from the tank. Store upright, away from heat sources above 125°F. See the Helium Safety Data Sheet (SDS) for full handling guidance.

Q: Does this ship to all US states?
A: This product ships as a compressed gas (UN1046, Proper Shipping Name: Helium, Compressed). It ships ground only via standard carriers. Check your local regulations for any restrictions on compressed gas shipments to your address.

Note* This is high purity helium and helium is the second smallest atom in the universe.Consider that helium nucli are so small that they can pass through gold foil without hitting other gold nucli.As discovered in the Rutherford Gold Experiment.When using high purity helium with latex a barrier should be used like HiFloat or Polyvinyl alcohol, To maximize float time on your balloon.It creates an extra barrier which slows down the rate at which helium escapes through latex.
