| Application: | Important basic building block for 13C labeled compounds. Also employed in astrophysical science and radiation chemistry. |
| Other Notes: | Stainless steel control valves Z146951, Z187224 or either of stainless steel regulators Z148504 and Z148512 is recommended. PTFE sealing washers GCA inlet size 180 Z146994 PTFE sealing washers CGA inlet size 110 Z146986 |
| 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 320 psig for 10 L. These pressures are slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder. |
