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 brass CGA 110/180 valve. Nominal gas pressures at 21ºC are 320 psig for 10 L and 625 psig for 25 L. 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 is recommended.

Soils contain the largest pool of terrestrial organic carbon (C) and are a major source of atmospheric carbon dioxide (CO2). Thus, they may play a key role in modulating climate change. Rising atmospheric CO2 is expected to stimulate plant growth

The capacity of organisms to sense changes in the levels of internal and external gases and to respond accordingly is central to a range of physiologic and pathophysiologic processes. Carbon dioxide, a primary product of oxidative metabolism is one such

Electricity can be an energy source for microbially catalyzed production of fuels and other organic commodities from carbon dioxide. These electrobiocommodities (E-BCs) can be produced directly via electrode-to-microbe electron transfer or indirectly with electrochemically generated electron donors such as H2

Stomata, the microscopic pores on the surface of the aerial parts of plants, are bordered by two specialized cells, known as guard cells, which control the stomatal aperture according to endogenous and environmental signals. Like most movements occurring in plants

The Southern Ocean is critically important to the oceanic uptake of anthropogenic CO2. Up to half of the excess CO2 currently in the ocean entered through the Southern Ocean. That uptake helps to maintain the global carbon balance and buffers
