Fan-filter units (FFUs) are the unsung heroes of controlled environment like cleanrooms, providing vital air filtration and circulation to maintain the clean conditions required by a wide range of industries. FFUs filter air to create or maintain a sterile environment within cleanrooms. Their primary function is to remove airborne contaminants, ensuring the air quality within […]

In the modern pharmaceutical industry, the choice between restrictive endoscopes (RABS) and isolators is one of the most critical decisions when designing a sterile process. Both systems can be designed to comply with GMP standards, and both are designed to minimize cross-contamination and protect the product. As experts in controlled contaminated environments, Master understands that […]

A RABS (Restricted Access Barrier System) is a physical barrier that limits direct access to critical areas. The system incorporates unidirectional airflow, positive pressure, HEPA filtration, and ergonomic glove port design. There are two main types of RABS: 1、Open RABS Environmental interaction: Installed in a classified room (usually Class B), limited interaction is allowed through glove […]
