- Aerobioscope — A laboratory apparatus used for collecting, filtering, and determining the number of microorganisms (bacteria, fungal spores) present in a specific volume of air. This device operates by bubbling air through a sterile liquid or by impacting particles onto a solid culture medium, being essential for air hygiene monitoring in hospitals, laboratories, and pharmaceutical industries.
- Aerotonometer — A laboratory apparatus or precision technical device used to measure the partial pressure or tension of gases dissolved in a liquid (such as blood) by means of hydro-gaseous equilibration. This structural instrument consists of sealed analysis chambers and fine barometric sensors, being essential in respiratory physiology research.
- Analyzer — An apparatus, device, or complex system used to perform an analysis. In biology, it represents an anatomical system consisting of a peripheral receptor, a conducting nerve pathway, and a central cortical area, responsible for receiving, transmitting, and transforming environmental stimuli into sensations. In technology, it denotes a measurement instrument or software program designed to automatically decompose and examine the components of a signal, an electrical or optical spectrum, or a chemical mixture.
