The purpose of using biosafety cabinets is to reduce the danger to the user when working with dangerous or potentially dangerous microorganisms. These cabinets do not necessarily protect the user from all hazards. In some safety cabinet types, the materials used for the purpose can be protection from environmental pollution. Measurement and verification tests are required to ensure the lowest performance criteria for safety cabinets working with microorganisms, to protect the environment and the worker, to protect the product and to prevent cross contamination (contamination).

Operational and Performance Verification Tests listed for Biosafety Cabinets are carried out in accordance with TS EN 12469:2004, WHO GLP:2004, ANSI/NSF 49:2014, ISO 14644-7:2004 standards and instructions.

CLASS I CABINETS: Air flow inward from the front opening, working with filtration of exhaust air and in a way that protects the worker.

in such a way that the output of the airborne particulate contamination formed in the cabinet can be controlled with the help of

A safety cabinet with a front opening where the user can perform manual operations inside the cabinet.

CLASS II CABINETS: Air flow inward from the front opening, working with filtration of exhaust air and in a way that protects the worker.

in such a way that the output of the airborne particulate contamination formed in the cabinet can be controlled with the help of

established, where the risk of product and cross-contamination is low, and where the user is inside the cabinet, manual operations

safety cabinet with a front opening that can

CLASS III CABINETS: The work area is completely closed and with a physical barrier (for example, mechanically) from the user’s work environment.

the safety cabinet where the gloves attached to the cabinet) are separated. The filtered air is continuously fed into the cabin and

The air is treated to prevent the emergence of microorganisms.

MEASUREMENTS WE PROVIDE SERVICE IN BIO-SAFETY CABINS PERFORMANCE EXAMINATION:-

– Control of Alarm Functions: It is the process of controlling the functional processes such as window opening, uv lamp, lighting, exhaust fan etc. in the bio-security cabinet.

– Down-flow Rate: It is the process of calculating the uniform value together with the determination of the required air flow values ​​in the standard in order for the bgk to protect the product.

– In-flow Rate (In-flow): It is the process of measuring the inward air flow from the front opening in order to protect the personnel working in the bgk.

– Filter Equipment Leakage Test: It is the process of detecting the leakage rate of hepa-ulpa filters in order to prevent unwanted particles from entering the bgk and contaminating the product and to safely discharge the toxic substances through the exhaust filter without affecting the personnel.

– Air Flow Direction Visualization Test:

– Lighting Measurement: Lighting should be suitable for safe operation in the cabin. The illuminance measured at the work surface

It should be at least 750 lux. The use of ultraviolet (UV) radiation in safe cabinets is not recommended. With this,

when necessary, lighting should be installed in such a way that it does not affect cabin performance and airflow. In the construction of the cabinet, materials that are not affected by UV light should be used. The electrical locking system should be provided in such a way as to prevent direct exposure of the worker to UV during the work in the cabin.

– Noise Measurement The sound levels in the cabin should be such that they do not disturb the attention of the employee. The A-weighted sound pressure level generated by the cabinet from any part of the installation should not exceed 65 dB.

– Particle Count
