Isolator

An isolator is a device or mechanism designed to separate or prevent the passage of something, such as sound, electricity, radio waves, or other forms of energy, from one system or environment to another. The primary function of an isolator is to block or minimize the impact of external factors, ensuring the stability, security, or integrity of the isolated entity. It is used in diverse applications, from protecting sensitive electronic components from voltage spikes to creating a sterile environment for medical procedures. Furthermore, an isolator can be a physical barrier, a specific material, or a functional component designed for a specific need.

Isolator meaning with examples

• In a medical laboratory, a containment isolator provides a sterile environment for cell cultures by preventing external contaminants from entering. The air filtration system and airtight design ensure the integrity of the experiments, protecting the samples from potential pathogens and maintaining controlled conditions. This is crucial for accurate results and the safety of personnel and samples.
• An electrical engineer uses an isolator circuit to prevent voltage surges from damaging sensitive equipment. The circuit acts like a one-way valve, allowing current to flow in one direction but blocking it in the other. This protects components by redirecting high voltage or current spikes safely, preventing equipment failure and enhancing system reliability.
• Radio frequency (RF) isolators are used in communication systems to prevent signal reflections from disrupting the signal path. They ensure signals travel in one direction only, which minimizes interference and maximizes power transfer. The design prevents signal interference and helps enhance signal stability for robust communication networks.
• A vibration isolator, made of a material like rubber, is installed between a machine and the floor to reduce the transmission of vibrations. It absorbs and dampens the vibrations produced by the machine, minimizing noise pollution and preventing damage to surrounding equipment. The outcome is reduced mechanical noise and extended equipment lifespan.
