III. Types of Biological Safety Cabinets

Biological safety cabinets are classified based on two main criteria: function and brand.

A. Classification by Function:

1. Horizontal Laminar Flow Biological Safety Cabinets:

The air flow is directed from the back through the working chamber horizontally, creating a protective barrier for users and specimens. This type is the most common and suitable for various applications.

2. Vertical Laminar Flow Biological Safety Cabinets:

The air flow is directed from above downward through the working chamber, providing a more effective sterile environment. This type is often used in applications requiring high safety, such as handling hazardous microorganisms.

B. Classification by Brand:

Several reputable brands of biological safety cabinets are trusted by laboratories both domestically and internationally. Notable brands include:

• SJ Clave - Korea: Leading brand for autoclaves and other laboratory equipment from Korea.

• LK Lab - Korea: Provides basic laboratory equipment.

• LaboGene: Korean brand offering cost-effective biological safety cabinets with good quality.

Note:

Choosing the appropriate biological safety cabinet depends on usage needs, budget, and laboratory space. Consulting with experts is recommended for selecting the most suitable product.
