Vakumlu

Vakumlu is a Turkish adjective meaning "having a vacuum" or "under vacuum." It is formed from the noun vakum (vacuum) with the adjectival suffix -lu, which yields a property or condition. The term is used across technical, industrial, and everyday language to describe objects, environments, or processes that involve a vacuum or operate at low pressure.

In practice, vakumlu is attached to nouns to specify vacuum conditions: vakumlu ambalaj (vacuum packaging), vakumlu tüp or vakumlu cihazlar (vacuum tubes or vacuum devices), vakumlu sistemler (vacuum systems), vakumlu fırın (vacuum oven). In scientific contexts, phrases such as vakumlu deneyler or vakumlu laboratuvar koşulları describe experiments or laboratory conditions conducted under vacuum.

Etymology and usage notes: Turkish vakum is borrowed from English vacuum. The suffix -lu is productive in Turkish, forming adjectives meaning "having" or "characterized by." The related form vakumsuz exists to describe non-vacuum conditions. Vakumlu appears primarily as an attributive adjective and is not typically a proper noun or brand by itself, though it can appear in product names or marketing to indicate vacuum-based features.
