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.

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.
Other Notes
Brass hose adapter Z146811 or brass body mini gas regulator Z513539 is recommended for 500 mL Sure/Pac cylinder (U.S only). For 1 L cylinder, either stainless steel control valve Z146951 or Z187224 is recommended.

β-Hydroxyperoxyl radicals are formed during atmospheric oxidation of unsaturated volatile organic compounds such as isoprene. They are intermediates in the combustion of alcohols. In these environments the unimolecular isomerization and decomposition of β-hydroxyperoxyl radicals may be of importance, either through
