Class 2 Safety Cabinets (EN 12469) / safety-cabinets approx. 120 cm

Microbiological safety cabinets 120 cm per EN 12469

Class 2 safety cabinets with a working width of approximately 120 cm are designed to protect personnel, products, and the environment when working with biological agents in risk groups 1 to 3. The EN 12469 standard defines the requirements for microbiological safety cabinets, ensuring that the units feature tested airflow, filtration, and safety functions. This working width is suitable for laboratories with moderate space requirements and allows for comfortable operation with standardised experimental setups.

Designs and Equipment

The available safety cabinets with 120 cm working width include models with manually and electrically adjustable front windows. Electric adjustment simplifies operation and allows for precise positioning of the protective screen during the work process. The Scanlaf Mars 1200 Runner features an internal width of 1200 mm and is TÜV-certified according to EN 12469, EN 61010-1, EN 61000-6, and EN 11201. The CleanAir BioVanguard 4 models are microbiological safety cabinets compliant with DIN 12469 and offer a choice of manual or electric front window adjustment.

Standards and Certifications

Certification according to EN 12469 documents compliance with European safety standards for microbiological safety cabinets. Additionally, the units meet standards such as EN 61010-1 (electrical safety of laboratory equipment), EN 61000-6 (electromagnetic compatibility), and EN 11201 (noise emission measurement). TÜV certification confirms independent testing and continuous quality assurance. This conformity is a prerequisite for use in GMP-regulated areas and for validation in pharmaceuticals and diagnostics.

Areas of Application

Microbiological safety cabinets with 120 cm width are used in laboratories for microbiology, virology, cell culture, genetic engineering, pharmaceuticals, diagnostics, and biotechnology. They provide protection when working with microorganisms, cell cultures, contaminated samples, and infectious materials. Class 2 compliance per EN 12469 enables the safe handling of biological agents while ensuring product protection through HEPA-filtered clean air. In pharmacies and clinics, they are used for aseptic preparation and sterile processing.

Selection Criteria

When selecting a safety cabinet with 120 cm working width, factors such as the required risk group of the biological agents, spatial conditions, frequency of use, and desired equipment should be considered. The internal width of 1200 mm offers sufficient space for common laboratory equipment and medium-sized experimental setups. The choice between manual and electric front window adjustment depends on comfort requirements and budget. Certification according to EN 12469 and TÜV testing are mandatory for regulated areas.

Accessories and Extraction Systems

For the safe operation of Class 2 safety cabinets, extraction systems and supplementary accessories are available. External extraction systems allow for connection to the building's exhaust air system and are necessary when working with volatile substances or when safety requirements are elevated. Gas burners for flame-free work and other equipment options enhance functionality. The selection of accessories depends on the specific workflows and microbiological requirements of the laboratory.

Frequently Asked Questions about 120 cm Safety Cabinets

The following answers refer to Class 2 microbiological safety cabinets with an approximate 120 cm working width according to EN 12469.

What are safety cabinets with 120 cm working width used for?

These safety cabinets serve to protect personnel, products, and the environment during microbiological work with biological agents in risk groups 1 to 3. They are used in laboratories for microbiology, cell culture, diagnostics, pharmaceuticals, and biotechnology for sterile processing, cell cultivation, and handling infectious materials.

Which working width is suitable for which laboratory requirement?

A working width of approximately 120 cm is suitable for laboratories with moderate space requirements and standardised experimental setups. It offers sufficient room for common laboratory equipment and processes without occupying excessive floor space. Smaller laboratories or individual workstations often choose units under 100 cm, while larger work areas prefer models with 150 cm or 180 cm width.

What does EN 12469 certification mean?

The EN 12469 standard establishes requirements for microbiological safety cabinets and defines test procedures for airflow, filtration, personnel protection, and product protection. Certification according to EN 12469 confirms that the safety cabinet features tested safety functions and is approved for handling biological agents. TÜV certification documents independent testing and quality assurance.

What is the difference between manual and electric front window adjustment?

With manual adjustment, the front window is moved by hand into the desired position and locked. Electric adjustment allows for convenient, motor-driven positioning at the touch of a button and enables more precise settings during the work process. Electric systems increase operating comfort, especially with frequent use or heavy front windows, but are more expensive to purchase.

Which accessories are useful for safety cabinets?

Key accessory components include external extraction systems for connection to the building's exhaust air, particularly when working with volatile substances or elevated safety requirements. Gas burners for flame-free work, UV lamps for disinfection, service ports, and ergonomic armrests complement the equipment. Selection depends on specific workflows and microbiological requirements.

How do I receive a quote or consultation for safety cabinets?

For professional advice on microbiological safety cabinets with 120 cm working width, interested parties can submit an enquiry to the specialist dealer. A needs analysis includes clarifying the risk group, spatial conditions, desired equipment, and any validation requirements. Based on this information, an individual quote is prepared, covering device selection, accessories, installation, and qualification.

What must be considered during commissioning and validation?

Class 2 safety cabinets according to EN 12469 must undergo performance testing before initial use and at regular intervals. This includes measuring airflow velocities, HEPA filter integrity testing, personnel protection testing, and functional testing of all safety devices. In GMP-regulated areas, documented qualification (IQ, OQ, PQ) is required. Regular maintenance and annual re-certification ensure continued protection.
