"filled with nothing" ???
yes is the answer your looking for, but the bulbs we use today are optimized to work with whatever gases each company uses.
Oxygen is the destroyer of fillaments (remember the old flash bulbs?)
A standard tungsten-element light bulb, there is no gas under the glass, it is a vacuum.
Incandescent light bulbs need to have an inert gas or a vacuum to prevent the filament from being surrounded by air (with oxygen) which would enable the filament to catch fire and burn. Inert gases used include argon, krypton and nitrogen or some combination of them.
Yes, modern incandescent bulbs are filled with an inert gas (argon,) but with a bit of nitrogen. Nitrogen is used because argon supports long sparks and leads to electric arcs and exploding light bulbs, and nitrogen interferes with this effect.
The purge canister is that black can in the front of cars and has wires and vacuum lines going to it, It is filled with charcoal.You just have to find out what is wrong. Start by checking the connections and vacuum lines and solonoid.
No, just an inert gas and mercury vapor at close to atmospheric pressure. Without the inert gas it would be near vacuum, as very little mercury is needed.
Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon. The earliest bulbs weren't filled with any gas, but had vacuum inside.
a manometer or vacuum gauge

the vacuums go back to the mid 1800s but they became electric in 1910 for the vacuum cleaner , 1931 for the electric guitar.

An ordinary household Incandescent type light bulb does not contain nitrogen gas. The bulb contains a vacuum surrounding the incandescent elements. There are other kinds of lights that do contain gases, Like Neon, argon and nitrogen but they are not commonly found in homes and and are not generally made as "Bulbs" being more commonly made as gas filled tubes.
Electric brooms do not work the same way as a conventional broom, because you do not have to sweep oi. Instead it works more like a vacuum cleaner. So it makes it more convenient for the user
The e4od is electronically controlled.
Flash chromatography uses pressure (under 10 psi) to pump solvent down a column at a rate faster than gravity would provide. Vacuum chromatography uses a vacuum at the bottom of the column to pull solvent through. Both can be performed with standard glass columns, but usually vacuum chromatography is done with a silica filled vacuum funnel instead as a rough purification technique.
