Custom Laminar Flow Cabinets

What Is Laminar Flow?

In relation to air movement, laminar flow is defined as a flow of air that is uniform in direction and velocity. Put simply, it’s air that is moving in the same direction, at exactly the same speed, creating a smooth and uninterrupted flow.

This comes in particularly useful in scientific laboratories, as it’s the perfect method for creating a contaminant-free work zone.

What are Laminar Flow Cabinets?

Laminar flow cabinets (also referred to as cell culture hoods, tissue culture hoods or laminar flow hoods) are specially designed laboratory enclosures. They’re made from stainless steel or polypropylene with no gaps or joints, meaning that there’s nowhere for things such as bacteria, spores or microbes to gather.

They have many applications across a variety of sectors, including (but not limited to) the medical, industrial, electronic and pharmaceutical professions, and are frequently used to work with semiconductors, biological samples or other materials of a sensitive nature.

How Does A Laminar Flow Cabinet Work?

In its simplest form, a laminar flow cabinet is made of three main components; a filter pad, a fan and a HEPA (High-Efficiency Particulate Air) filter. It works like this:

1. The fan pulls air from the room through the filter pad, collecting and removing the larger dust particles.
2. This semi-filtered air then passes through the HEPA filter, which will remove the smaller dust particles, along with any airborne fungus or bacteria.
3. The filtered and sterile air is now free to flow through into the workspace, essentially creating a barrier that defends the area from outside contamination.

How Do I Find The Right Type Of Laminar Flow Cabinet?

All of our laminar flow cabinets are fully customisable and can be made without an added “bespoke” price addition. We provide a wide array of options, including variable width, depth, height, bench-top/stand-mounted, gas taps, optional sliding sash, UV lighting and internal removable shelves.
