Working with deuterated solvents

Turn on gas cylinder using main regulator
Adjust with secondary regulator so that max PSI is about 150
Place deuterated solvent under the nozzle and open cap
Open and adjust tertiary regulator so that air flow is strong enough to displace headspace in the bottle but not so fast that things splash out
Keep bottle under nozzle when not using it
When finished tighten and seal bottle and turn off cylinder at main regulator
Close tertiary regulator
Close Hood

Deuterated solvents are expensive and must be treated with care to prevent exchange with H2O in the air.
Remember to tighten and seal all deuterated solvent bottles after each use
