Laminar Clean Bench Advanced Filtration Technology for Contamination Control in Sensitive Operations

‌Clean Bench‌

A clean bench (also known as a laminar flow cabinet or purification workstation) is a specialized device that uses air purification technology to create a localized high-cleanliness environment. It is primarily used in precision operations sensitive to microorganisms and particulate contamination. Below are its key aspects:

‌1. Definition and Function‌

• ‌Definition‌: A clean bench is an enclosed air purification system that provides an ISO Class 5 (Class 100) particle-free and sterile environment. It uses filtration systems to control air cleanliness and directs pollutants away to protect both operators and the environment‌
• ‌Core Function‌: Maintains unidirectional airflow (vertical or horizontal) to isolate the workspace from external contamination, ensuring high cleanliness for sensitive operations or experimental samples‌

‌2. Working Principle‌

1. ‌Air Filtration Process‌

   • ‌Pre-filtration‌: Captures large particles and contaminants‌
   • ‌HEPA/ULPA Filtration‌: High-efficiency filters (99.99%+ efficiency) distribute air evenly via a plenum chamber‌
   • ‌Clean Airflow Output‌: Generates laminar airflow with uniform velocity to sustain workspace cleanliness‌

2. ‌Contaminant Control‌
   Contaminated air is filtered and expelled through designated channels to prevent secondary pollution‌

‌3. Key Applications‌

• ‌Biopharmaceuticals‌: Cell culture, vaccine preparation, and other microbe-sensitive tasks‌
• ‌Electronics Manufacturing‌: Semiconductor production, precision optical component assembly‌
• ‌Medical Research‌: Sterile reagent preparation, tissue engineering experiments‌
• ‌Food Testing‌: Microbial analysis, sterile packaging validation‌

‌4. Technical Features‌

• ‌Adjustable Design‌: Equipped with adjustable-speed fans, sliding doors, etc., to accommodate diverse workflows‌
• ‌Safety Protection‌: Biosafety models prevent hazardous material leakage‌
• ‌Low-Interference Environment‌: Minimizes noise, vibration, and optimized lighting for precision work‌
