The core focus of a laminar flow clean bench is to provide an ultra-clean environment for the operating area, making every effort to prevent tiny particles such as external dust and microorganisms from entering the operating tabletop and protecting experimental samples from contamination. For example, in a cell culture experiment, the laminar flow clean bench builds a "clean barrier" to keep delicate cells free from dust interference and maintain their good growth state. It emphasizes product protection, and the main object of protection is the sample. It is usually applicable to ordinary microbiological experiments, cell operations and other work that poses no significant biological hazard risks to personnel and the surrounding environment.
The mainstream airflow patterns of laminar flow clean benches are vertical laminar flow or horizontal laminar flow. The vertical laminar flow is like a "clean waterfall" flowing from top to bottom. The air is evenly blown vertically from the high-efficiency filter at the top, taking away the dust in the operating area and quickly settling it below the tabletop to ensure the continuous cleanliness of the tabletop. The horizontal laminar flow is like a stable "airflow belt" flowing from one side to the other, helping materials to be free from contamination in the horizontal direction. Most laminar flow clean benches have a circulating air system. Part of the air returns to the operating area after being filtered by high-efficiency filters, which is energy-efficient and maintains a stable clean airflow.
Laminar flow clean benches have a simple design and are mostly open-style, with a wide tabletop that is conducive to the layout of experimental operations. There are no thick and closed enclosures, allowing operators to stretch their hands freely and have a broad view. Equipped with an illumination system, even subtle operations can be precisely controlled. They are easy to operate. Just turn on the fan and adjust the wind speed, and even beginners can quickly get started. The equipment is lightweight and takes up little space, making it suitable for small laboratories with limited space.
Laminar flow clean benches shine brightly in the field of cell engineering with their excellent cleanliness performance, such as in the preparation of monoclonal antibodies and the cultivation of stem cells. They are also commonly seen in the precision assembly of electronic components and the processing of optical elements, safeguarding the assembly of tiny parts without interference from impurities.
