Laminar floor hood is a must for your laboratory if you’re cautious about contamination. It consists of a fan and a filter pad which emits HEPA (High-Efficiency Particulate Air) filtered air into the workspace to provide a clean area for carrying out product task.  It typically clears particles a uniform way, from the cleanest region below the hood, which is the face of the filter, to the area of exit. This very design of laminar flow is without a doubt the best way to keep the environment of your laboratory germ-free and as clean as possible. It also acts as a space-saving instrument.

Types of Laminar Flow Hood

The laminar flow hood is designed in two ways, one is Vertical laminar flow hood in which the air is filtered through the top of the enclosure and directed downwards at the surface of work, keeping the speed constant throughout. The other is Horizontal laminar flow hood which filters the air horizontally from over the surface of work in the direction of the operator, at a constant speed.

Both designs provide product protection and give a generous and sufficiently bright work surface for full product protection and client comfort.

Your choice of the Laminar flow design should be based entirely on the kind of application you would prefer. There are plausible reasons to choose either one of the flow systems based on the requirement of clearance, work surface plan, safety of operator and process location.

If you are thinking of going for the horizontal laminar flow here are some essential points you should consider in order to make a rational choice:

PRO

1. They generally have a taller and subsequently a bigger stacking and working region. Thus providing a bigger space for instruments like microscopes to be set inside.
2. Minimal laminar air stream obstruction. The flow does not encounter disruptions due to the work surface.
3. The lack of a sash helps putting the equipments and instruments inside without any strain.
4. Fewer issues of contamination through hands or safety equipment like gloves as they are downstream of the particular specimen.
5. They are commonly the favored selection for preparation of media plate, gadgets inspection, plant tissue structures, medical device gathering, and drug store preparation.

CON

6. While the airflow may not experience large obstructions under the hood, it obviously does encounter the person at work. Any irritable substances, for example, fine powders or brazing fumes might be blown into the administrator’s face.
7. This impact may not affect the laminar airflow, it might cause some health risk.
8. Its filter change and servicing generally requires its laminar hood to be repositioned for rear access.
9. Working with bigger specimens can cause obstruction in the airflow and possibly contaminate downstream specimens.
10. For operations involving materials such as liquids and small substances, a horizontal airflow design is more suited as it abstains from picking up particles off the surface below.
