Nitrogen N5.5 (Research Grade N2) Cylinder

Before using Nitrogen N5.5 in any new process or experiment, a thorough material
compatibility and safety study should be carried out. Ensure adequate air ventilation.
Ensure all national/local regulations are observed. Whilst proper care has been
taken in the preparation of this document, no liability for injury or damage resulting
from its use can be accepted. Note: When the Product Name appears in the SDS
header the decimal sign and its position comply with rules for the structure and
drafting of international standards, and is a comma on the line. As an example 2,000
is two (to three decimal places) and not two thousand, whilst 1.000 is one thousand
and not one (to three decimal places).

Pure gases are classified by grade.

The first digit of the grade classification indicates the ‘number of nines’ purity, e.g. N3.0 = 99.9% purity.

The second digit is the number following the last nine, e.g. N4.6 helium has a guaranteed minimum purity level of 99.996%.
