Helium is a colorless, odorless, and inert gas that is the second lightest and second most abundant element in the observable universe. It is primarily extracted from natural gas reserves and is known for its low boiling point and non-reactive properties. Helium is typically used in applications requiring a safe, non-flammable gas, such as in cryogenics, pressurizing and purging systems, and as a lifting gas in balloons and airships.
| Purity | 99.99% or higher |
| Boiling Point | -268.93°C |
| Molecular Weight | 4.0026 g/mol |
| State at Room Temperature | Gas |
| CAS Number | 7440-59-7 |
When purchasing helium, buyers should consider the purity level required for their specific application, as higher purity levels are essential for sensitive uses such as medical or scientific applications. It is also important to specify the quantity needed, as helium is often supplied in various cylinder sizes or bulk quantities. Additionally, buyers may want to inquire about certifications related to safety and quality standards.
