Packaging: | 500 mL in Sure/Pac™ |
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. |
Packaging: | 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. |
Packaging: | 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: | 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. PTFE sealing washers GCA inlet size 180 Z146994 PTFE sealing washers CGA inlet size 110 Z146986 |
