Description

Packaging

500 mL quantity is packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve. Nominal gas pressure at 21ºC is 3.6 psig for 500 mL. This pressure is slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder.

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.
