The difference is in the packaging. The 364584-1L-EU is under low pressure to meet EU regulatory requirements, therefore it requires a different regulator type, as opposed to the 364584-1L. See below for accessories for the 364584-1L-EU.

Application
Nitrogen-15N2 (15N Labeled nitrogen) can be used:
- In nitrogen fixation experiments to monitor the resulting metabolites in an organism.[1]
- 15N2 pulse-chase experiments to understand the route of transport of fixed nitrogen from the nodule to the shoot in plants.[2]
- To quantify biological N2 production in agricultural soil.[3]
Packaging
250 mL and 500 mL quantities are packaged in a 25 mL Sure/Pac™ cylinder with brass 1/4" male NPT valve. Nominal gas pressures at 21ºC are 135 psig for 250 mL and 275 psig for 500 mL.
Quantities of 1 L and 5 L 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 I L and 155 psig for 5 L.
Cylinder pressures are slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder.

Legumes obtain nitrogen from air through rhizobia residing in root nodules. Some species of rhizobia can colonize cereals but do not fix nitrogen on them. Disabling native regulation can turn on nitrogenase expression, even in the presence of nitrogenous fertilizer

Ammonium is a central nutrient in aquatic systems. Yet, cell-specific ammonium assimilation among diverse functional plankton is poorly documented in field communities. Combining stable-isotope incubations (15N-ammonium, 15N2 and 13C-bicarbonate) with secondary-ion mass spectrometry, we quantified bulk ammonium dynamics, N2-fixation and
