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: 99.9-99.999%
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
