The phrase "air flask" is not a standard or widely recognized term in written English.
It may be used in specific contexts, such as discussing a container for air or a device related to aerodynamics, but clarity is essential.
Example: "The engineer designed a new air flask to improve the efficiency of the jet engine."
Alternatives: "air container" or "aerodynamic flask".
For instance, small air flasks can easily be controlled so far as there do not exist wind and turbulence.
Two reload torpedoes were also carried; their air flasks, however, had to be charged before they could be used, a process that took several hours.
Then, without removing air, the flask was sealed with a cork and placed in oil bath at 120°C with stirring at 400 rpm for 1 h.
The batch photoreactor was an open to air cylindrical flask and the visible light was provided by a 300 W Xe lamp with a UV cutoff filter (λ > 420 nm).
To test the atom trap on ancient ice, study authors obtained more than 600 pounds of ice chunks from Taylor Glacier, Antarctica, melted them down, trapped the escaped air in flasks and had it analyzed.
The air in the flask was replaced by nitrogen, and then the flask was placed in a constant temperature oil bath at desired temperature.
Before being closed, the bottles were flushed with nitrogen gas (N2) to remove air in the flask head prior to incubation; the temperature was maintained at 35 ± 1 °C.
The Global Monitoring Division of the National Oceanic and Atmospheric Administration/Earth System Research Laboratory (NOAA/ESRL) has also collected discrete air samples in flasks and in situ measurements from remote sites across the globe and analyzed them for a suite of species including N2O.
Gaseous N2 was applied to remove air from the flasks.
Effluents of vessels were collected in air tight glass flasks which were stored on ice to inhibit microbial fermentation.
