RICO Vertical Laminar Air Flow is conceptualized to provide fully functioning bath area in high efficiency full air, which is free from any type of particle contamination or impurities. These units are ideally suited in all applications, which require the protection of biological samples or products with potential contamination during processing or testing. Our Laminar Air Flow Bench is rapidly gaining popularity in other areas, such as pharmaceutical production, electronic industry and various other manufacturing applications.

A vertical clean bench pushes the air through a HEPA filter which is located at the top of the enclosure. At constant speed, the wind is directed downwards on the work surface.

It is useful for various tasks, which require the maintenance and purity of plant's tissue culture, purity and electronic electronic parts, medical science, entomology, pharmacy, agricultural sector, seed science, veterinary science, and experiments like purity.

On the other hand, a vertical clean bench provides a pivot glass sash as a safety measure. This sash provides personal protection and a physical barrier while working with chemicals. In the microbiology, forensics, biotech and many other industries vertical clean benches are common places, which are used during those processes which require a clean work area.

Special Features
