Packaging

All gas volumes are quoted at Standard Temperature and Pressure (STP) and not at Normal Temperature and Pressure (NTP). One STP Liter is 7.7% more gas than one NTP Liter.
Standard products are packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve. Nominal gas pressures at 21ºC are 20 psig for 1 L and 290 psig for 10 L. These pressures are slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder.

Other Notes

Stainless steel control valve Z146951 or Z187224 is recommended.
