Description:
1.Neon is a rare atmospheric gas which is odorless, colorless, tasteless, nontoxic, monatomic and chemically inert. The concentration of Neon in the atmosphere, by volume percent, is 1.8 x 10-3.
2.Our high purity neon in 5N were good in sales in the past year for export 400 cylinders per month .
The quality details as follows:

Applications:
1. Neon is often used in signs and produces an unmistakable bright reddish-orange light.
2. Neon is used in vacuum tubes , high-voltage indicators, lighting arresters,wave meter tubes,televsion
tubes,and helium-neon lasers.
3. Neon is used in some plasma tube and refrigerant applications but has few other commercial uses.
It is commercially extracted by the fractional distillation of liquid air.Since air is the only source, it is
considerably more expensive than helium.

FAQ
1.What's your product price?
Because each gas price is depends on the market supply and demand, quantity and purity, it is difficult to give a fixed price. If you have any interested in each gas, pls give your details requirement. I could like to make an offer to you.
2.What's the min order?
Different products have different min order. Please don't hesitate to let me know your requirement.
3.What's the delivery time?
If the cylinder is in stock, and only need to fill gas, the delivery is about 7-10 days ex work after receive the deposit.
If the cylinder need to customize, the delivery is about 15-35 days ex work after receive the deposit. That depends on the quantity.
4.How to check the gas quality?
Firstly, our cylinder will take a treatment (cleaning, drying, vacuum pumping, and replacement before filling gas. In this way, the cylinder inside is clear and dry. Secondly, we will take tests every treated cylinder to assure them inside purity. Thirdly, we will take a test for all of the gas after fill into cylinders. If the tested gas is not up to standard, we will produce it again and not release the faulty product to ex work. At last, we will supply you the gas testing qualified report .
5.All the cylinders can be recycled?
Usually seamless steel cylinder can be recycled to use in 20 years.
The disposable cylinder is only use for one time.
6.Shall we send back the cylinders to China to refill gas again?
Yes, when you ordered our cylinders, next time, you can send back the cylinders to fill gas again. You just need to tell us before you export. We will handle all the import customs clearance formalities.
