Pure gases from Hong Kong Specialty
Gases are classified by grade, since common purity designations
such as Perpurified or High Purity vary among different suppliers
and therefore have little meaning. Please read the following table
for more information about the grading of our gases.
Each Pure Gas listing includes a recommendation for
the proper regulator or manual control valve. The particular piece
of equipment listed has been selectred on the basis of compatibility
with the physical and chemical properties of the gas and its level
of purity. A complete listing of the comprehensive line of Specialty
