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 500 mL quantitiy is packaged in a 25 mL Sure/Pac cylinder with brass 1/4" male NPT valve. Nominal gas pressure at 21ºC is 220 psig for 500 mL.
Standard 1 L quantity is packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180. Nominal gas pressure at 21ºC is 20 psig for 1 L.
Because of the relatively low cylinder pressures, care must be taken when extracting this product from the cylinder.
