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
-
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
-
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
