Packaging

10 L quantity is packaged in a 450 mL carbon steel lecture bottle with stainless steel CGA 110/180 valve. Nominal gas pressure at 21ºC is 114 psig for 10 L. 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.
This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.
