| Application: | Important basic building block for 13C labeled compounds. |
| Packaging: | 1 L in steel cylinder |
| 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 products are packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve . Nominal gas pressures at 21ºC are 20 psig for 1 L and 290 psig for 10 L. These pressures are slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder. |
| Recommended products: | 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 |
