Best practice

When describing scientific experiments or material storage, use "kept in vacuum" to clearly indicate a controlled, air-free environment, which is crucial for preventing oxidation, contamination, or other unwanted reactions. Be specific about the duration and conditions of vacuum storage.

Common error

Avoid using "kept in vacuum" without specifying the level of vacuum achieved (e.g., high vacuum, ultra-high vacuum). Different applications require different vacuum levels, and failing to specify can mislead the reader about the actual experimental or storage conditions.

Linguistic Context

The phrase "kept in vacuum" functions as a prepositional phrase, often acting as an adverbial modifier to describe the conditions under which something is maintained or stored. Ludwig provides examples illustrating its use across diverse contexts.
