Laminar Air Flow Testing

The operation cleaning maintenance and qualification of laminar air flow laf shall discussed in below sop.

Laminar air flow testing.

The definition of laminar airflow is air moving at the same speed and in the same direction with no crossing of streams. Today many categories of laminar flow hoods exist. Sop on laminar air flow laf operation cleaning and qualification microbiology laminar air flow airflow which is linear and positive up to working surfaces and thus prevents contamination of surrounding viable non viable particulate matter in aseptic handling. Laminar flow consultants has been in the business of delivering quality air testing since 1973.

Hepa filter integrity testing looks for any leaks or other defects that might allow unfiltered air to enter the workspace. Also called particle pollution. The air will deposit mostly invisible particles on nearby surfaces when the airflow is not laminar. Laminar flow hood testing.

Clean workstations and laminar flow hoods provide a controlled work surface through hepa filtered air that is exhausted across a work surface in a laminar or unidirectional air stream creating a clean work zone. According to the cdc the laminar air flow principle was first developed in the early 1960s. Effective hepa filtration is a crucial component of any functional laminar flow hood. While there may be a variety of methods to overcome these risks air science laminar flow products incorpo rate sound design principles to effectively meet usp 797 and iest testing standards.

Serving the mid atlantic region and beyond. Laminar flow hoods are designed to provide hepa filtered unidirectional airflow to a work area in which clean high quality applications and processes are required. Although they differ depending on the science performed. Uniform airflow is critical to the functioning of a laminar flow hood.

It s still incredibly relevant for modern labs having literally shaped the way air safely moves in many generations of laboratory enclosures. Tion in the flow pattern of the air through the cabinet can result in stagnant or contaminated air being able to come in contact with critical sites. Laminar flow hoods provide a sterile working environment for product protection. This is achieved by total removal of air borne droplet nuclei and dust borne bacteria by unidirectional oriented streamlines of clean air at velocities designed to flush contaminating particulates.

Air flow smoke pattern testing for usp 797 compliance share various standards covering sterile operations including usp 797 the fda aseptic processing guide and state boards of pharmacy require an airflow visualization study to prove that the primary engineering controls pec are suitable for the intended activity. Environments that are sensitive to particle. Laminar air flow laf work station is capable of maintaining a particulate free work area even when operated in an uncontrolled environment.
