Description

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 stainless steel CGA 110/180 valve. Nominal pressure at 21ºC for both 10 L and 25 L standard package is 114 psig (liquified). This pressure is slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder.

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.

Recommended products

Stainless steel control valves Z146951, Z187224 or either of stainless steel regulators Z148504 and Z148512 and a "T"-purge valve Z151661 is recommended.
