| Fume Hood | Designed to vent hazardous fumes and vapors away from the user. | Chemical handling and synthesis processes. |
Understanding Laminar Flow Technology
Laminar flow technology is based on the principle of airflow. In laminar flow hoods, air is drawn through a HEPA filter, producing a smooth and unidirectional airflow that minimizes turbulence. This air is then directed over the work surface, creating a sterile environment ideal for sensitive tasks. The efficiency of these hoods largely depends on their design and the quality of the filters used.
Benefits of Using Laminar Flow Hoods
- Contamination Control: By providing a sterile workspace, laminar flow hoods effectively protect samples from airborne contaminants.
- User Safety: In the case of biosafety cabinets, they also offer protection to the user from hazardous materials.
- Versatility: These hoods can be used across various industries, including pharmaceuticals, biotechnology, and electronics.
Factors to Consider When Buying Used Laminar Flow Hoods
When purchasing a used laminar flow hood, consider the following factors:
- Condition: Assess the physical and operational condition of the hood. Look for wear and tear, and inquire about its maintenance history.
- Certification: Ensure the hood has been tested and certified for performance, especially if it’s a biosafety cabinet.
- Size and Configuration: Choose a size that fits your laboratory space and meets your workflow needs.
- Brand Reputation: Brands like Thermo Fisher Scientific, NuAire, and Esco are recognized for their quality and reliability.
