Product Description



Product Description
Introduction
Helium is a highly inert gas found in nature in limited quantities. It is colorless, odorless, non-flammable and non-toxic. Liquid Helium is the coldest known substance. Special transportation and storage equipment is required for minimizing losses of product.
Name: helium gas
Purity: 99.999%-99.9999%
Property: colourless, odourless, non-flammable, non-reactive, inert gas
Application:
Helium is the second element in the periodic table and owing to it's non-flammable nature and lightweight, replaces Hydrogen in the metrological applications. It is a critical element in many applications and is used in numerous other applications in line with it's highly inert and stable characteristics. Major applications are as under:
Common applications include:Cooling of magnet used in MRI machinesBalloon inflationLeak detectionElectronicsBreathing mixtures for divers
Package: 200bar or 150bar cylinder or packed according to demand

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, pleases give your details requirement.We can negotiate the most reasonable price. 2.What's the minimum order quantity? Different products have different minimum order quantity. Please don't hesitate to let me know your requirement. 3.What's the delivery time? If the cylinder need to customize, the delivery is about 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 . |
