China Biosafety Safety Cabinet Type II Type B2 Biological Safety Cabinet

A biosafety cabinet (BSC), also known as a safety cabinet, is a critical piece of equipment used in laboratories to protect the operator, samples, and environment from biological hazards. As a professional safety cabinet manufacturer in China, we provide high-performance and reliable biosafety cabinets designed for clinical laboratories, hospitals, pharmaceutical facilities, and research institutes.

Protection Principle and Structure

Our biosafety cabinets are engineered with a negative pressure airflow system and high-efficiency HEPA filtration, ensuring triple protection for personnel, samples, and the environment.

Key structural components include:

• High-quality stainless steel inner chamber
• Energy-efficient fan systemPrimary filters + HEPA filters
• Ergonomic work surface
• LED lighting and intelligent control panel

Working principle:

• Ambient air enters through the front intake grille.
• The air passes through pre-filters and HEPA filters to ensure a clean work environment.Exhaust air is filtered again through HEPA filters before being released, preventing any harmful microorganisms from escaping.
• This design guarantees safe, clean, and contamination-free laboratory operations.

Safety Levels and Classification

Biosafety cabinets are classified into three main types based on protection level:

Class I Safety Cabinet

Protects personnel and environment

Suitable for low-risk microorganisms

Common in basic microbiology and educational labs

Class II Safety Cabinet (Most widely used worldwide)

Protects personnel, products, and environment

Ideal for hospitals, pathology labs, microbiology testing, and pharmaceutical environments

Class III Safety Cabinet

A fully sealed, maximum-protection system

Used for high-risk pathogens such as Ebola, smallpox, and other dangerous viruses

As a safety cabinet supplier in China, we provide a full range of Class I, II, and III biosafety cabinets to meet different laboratory requirements.
