隔膜

1. Origins, structure, and basic meaning

• Structure: 隔膜 is read as かくまく and is a noun for a thin membrane that separates parts of a device or space.
• Basic usage: It appears in technical descriptions such as 装置内部の隔膜 and 薄い隔膜で分ける.

2. Common pitfalls and similar expressions

• Membrane, not any partition
  • In these examples it is a thin membrane, so do not extend it automatically to every wall or rigid divider.
• Context controls the referent
  • The word can occur in biological contexts, but the supplied examples concern a device and a membrane separating liquids.
