What type of material is used for rigid isolator equipment?

The correct answer identifies the materials commonly used for rigid isolator equipment, which are designed to provide a controlled environment for laboratory animals and ensure their safety and health during procedures. Rigid isolators need to be durable, easy to sterilize, and capable of maintaining a sterile environment.

Stainless steel is a preferred material due to its resistant properties against corrosion, ease of cleaning, and ability to withstand various sterilization processes. Plexiglass, on the other hand, allows for clear visibility while also being relatively easy to clean and maintain. Together, these materials create an effective and reliable barrier against contamination, allowing researchers to handle and observe animals without directly interacting with them.

In contrast, clear plastic film and metal mesh, while useful in certain applications, do not offer the same level of sterility and rigidity required for isolators. Wooden panels are not suitable due to their porous nature, which can harbor bacteria and other contaminants, making them ineffective for maintaining a sterile environment. Therefore, the combination of stainless steel and plexiglass in rigid isolator equipment ensures both functionality and safety in laboratory settings.
