Electron Grade Helium 3 Isotope 3 He For Detectors Aluminum Cylinder

Description:

1. Helium-3 is a stable and lighter isotope of ordinary Helium. It is odorless, colorless and taste-less. The natural abundance of Helium-3 is 1.38 x 10-6. Helium-3 is principally shipped and used in gaseous form for detectors, NMR tracers, spectroscopy, low temperature physics, la-sers, dilution refrigerators and R & D laboratories research.

2. Newradar Special Gas Material Safety Data Sheets (MSDS) are available for Helium-3 gas and should be used as guidelines in regard to first aid, methods of storage, handling and general use of Helium-3.
