Small bottle of helium includes: (one air nozzle + one bottle + helium gas (gas in the bottle)), large bottle of helium includes: (one air nozzle + one bottle + helium gas (gas in the bottle)). Each helium bottle sent out must be tested to ensure that the gas is sufficient before sending. Please rest assured that you will not receive helium bottles with insufficient or insufficient gas. The color of the helium bottle is randomly sent, dear friends!Notes

· Please carefully read our product description before purchasing!

If you have any questions, please contact customer service to answer questions before you make a purchase!

The color of the large and small helium tank cylinders is randomly sent!

·This helium gas can only be used to inflate latex balloons larger than 10 inches, and aluminum film balloons need to be larger than 18 inches to fly.

Latex balloons last only about 5 hours, so you can only inflate them 30 minutes before the event.1Fill it for an hour, and make sure to tie the balloon tightly. Don't fill it too early, or it won't work by the time you need it. 

· These helium tanks are disposable items. Once the buyer has opened and used them, they cannot be resold and are not eligible for a refund or exchange!

Let's start with hydrogen!
Generic Name: Hydrogen
英文名称：hydrogen
Chemical formula: H2
Hydrogen is the lightest gas in the world. Its density is very low, only one-fourteenth that of air. Under standard conditions, 1 liter of hydrogen has a mass of 0.0899 grams. Since hydrogen is a gas with very low density, when we inflate an aluminum foil balloon with hydrogen, it can float in the air.
Hydrogen is a colorless, odorless, and tasteless, flammable and explosive gas. Experimental determination shows that if the volume of hydrogen mixed into the air reaches 4% to 74.2% of the total volume, an explosion will occur when there is a flame. Hydrogen and fluorine, chlorine, oxygen, carbon monoxide, and air all have the risk of explosion, and among them, the mixture of hydrogen and fluorine can spontaneously explode in low temperature and dark environments, and the mixture ratio of 1:1 with chlorine can explode under light. Since hydrogen is colorless and odorless, and the flame is transparent when it burns, it is difficult to be detected when it burns. We should know that the air we breathe every day contains gases such as hydrogen and fluorine, chlorine, oxygen, carbon monoxide, and I don't need to say that everyone should know the consequences of using hydrogen.
Currently, the market price of hydrogen is 8-12 yuan per cubic meter, which means when you buy a standard bottle of 6 cubic meters of hydrogen from a gas supply station, the price should be around 60 yuan. A bottle of 6 cubic meters of hydrogen can inflate 18-inch aluminum foil balloons between 300-350 times, so the cost of each aluminum foil balloon should be around 0.20 yuan. Compared to the price of a single balloon, it is quite cheap.

Now that we've talked about hydrogen, let's move on to helium!
Generic Name: Helium
英文名称：helium
Chemical formula: He
Helium has a density of 0.1786 kg/m3, which means that 1 liter of helium weighs 0.17847 grams. It is the lightest gas except for hydrogen. Therefore, when we inflate our aluminum foil balloons with helium, it can also make our aluminum foil balloons rise into the air.
Helium is an inert gas that is colorless, odorless, and tasteless at room temperature. When we talk about inert gases, we may not be familiar with the concept. The term "inert" comes from the Latin word "inertus," which means "lazy." The term "noble gas" comes from the Greek word "nobos," which means "noble." These elements are given these names because of their aloof and exclusive characteristics. Under normal conditions, helium does not react with other elements or compounds. Because of its "laziness," we call it an inert gas.
Helium is the most difficult gas to liquefy, extremely inactive, cannot burn, nor does it help burn. It can be extracted from natural gas containing helium of up to 7%. It can also be produced from a mixture of helium and neon in liquid air by fractional distillation. However, due to its extremely low content in the air and low production, high production costs, helium is mainly extracted from natural gas when a large amount is needed. As long as natural gas contains more than 0.2% helium, it has the value of extraction.
Taking into account what has been discussed, helium is produced in low quantities and has relatively high extraction costs, which is why it is currently much more expensive on the market compared to hydrogen. The price of a 6-cubic-meter helium bottle currently ranges from 700-800 yuan, with the highest reaching 1,200 yuan per standard bottle last year. Now let's revisit the price comparison between helium and hydrogen. If the same 6-cubic-meter helium can inflate 300-350 aluminum film balloons, then its price per balloon should be more than 2 yuan, which is more than 10 times the price of hydrogen at 0.20 yuan per balloon.
Now that we've discussed it, we should have a clear understanding of the characteristics of hydrogen and helium. We should also be able to decide which gas to use to inflate our latex balloons. I'm sure we've heard about the explosion that occurred at the opening ceremony of the sports meet, where students from Lanzhou Electric Power School were holding hydrogen balloons. Moreover, the relevant national laws stipulate that using hydrogen to inflate latex balloons is a product subject to strict government management. It must be approved and released by specialized agencies, and the number of balloons to be released, the location, and the organization and planning of the release are all clearly regulated. It is absolutely forbidden for individuals or organizations without qualifications to release balloons at will. Holding hydrogen balloons is also strictly prohibited. Whether it is right or wrong, each person has their own opinion. Please consider it for yourself.

Today, we happened to talk about hydrogen and helium, so I'll just mention it casually. Many friends often don't understand what helium balloons and hydrogen balloons are. In fact, it's a very simple concept. If you inflate our latex balloons with helium, then these latex balloons are called helium balloons. If you inflate our latex balloons with hydrogen, then these latex balloons are called hydrogen balloons.

Balloons are excellent decorations and promotional gifts. Print the company logo on the surface of the balloon,

It's a great promotional method. It can be used in any situation.

The price is low. The effect is better. Welcome to consult and negotiate if you need the product.

Operating Instructions:

1Attach the air nozzle.

2Open the valve

3The balloon to be inflated is placed over the inflator nozzle.

4Press the air nozzle to begin the air filling.

5After the balloon is inflated to the required size, the air vent can be returned to its original position.

6Tie a knot in the balloon and ribbon to complete the inflation.

Note: After filling the balloon, if you do not need to inflate it again, please close the valve of the helium bottle to prevent any remaining helium from leaking.

Our company supplies helium gas cylinders and welcomes inquiries and orders.

The advantage of helium over hydrogen lies in the fact that balloons filled with helium can also achieve the effect of floating, and they are less likely to explode, whereas hydrogen balloons can self-detonate.

The price is not much more expensive than hydrogen, and it is durable and affordable, so it is naturally the air tank for inflating balloons.

Our company offers small quantity wholesale with discounts for larger quantities. Please feel free to call for more information.
