These days, workplaces are becoming complex as technical equipment has become a part of the work here. The equipment may be used to complete tasks, keep workers safe, or perform any other function. Science labs for research have become the backbone of these developments. Since it is not possible to perform tests and experiments in the labs without setting up a sterile environment, laboratories often need highly sophisticated tools, such as vertical and horizontal laminar flow hoods.

How does a laminar flow hood work?

A laminar flow hood is installed at the top or on the back of a workstation. It comes with a HEPA filter. The hood draws the air in the lab first. It then goes through the filter and gets purified. All contaminants and hazardous substances are eliminated from the air. In the end, clean and purified air is released by the flow hood in the lab. The air is not removed from the space; it is only recycled.

Types of laminar flow hoods

According to how the laminar flow hoods draw and release air, they are divided into two categories, such as:

Vertical laminar flow hoods: These laminar flow hoods are installed at the top of the unit. So, they draw air in from above and then release it vertically so it flows downward. It is easy to install and compact vertical laminar flow hoods as the filters can be attached to most lab workstations easily.

Horizontal laminar flow hoods: Unlike vertical hoods, horizontal laminar flow hoods release air horizontally from the back of the unit towards the front. Horizontal flow workstations have greater depth than vertical ones. These laminar flow hoods are quite sensitive because the filtering process offers a horizontal flow to air currents without mutual disturbance. So, they are ideal for labs where researchers are involved with small and sensitive samples with very low contamination tolerance.

Reasons to use laminar flow hoods in labs

Laminar flow hoods are very useful in a work environment of a lab. The reasons they are used in laboratories are:

Keeping sensitive items sterile: Any operation or experiment in a science lab depends on highly accurate chemical reactions, such as virus isolation, soldering of microprocessors, and the testing of drugs and treatments upon viral or bacterial cultures. Even the slightest contaminant is enough to hinder these tests. Laminar flow hoods eliminate these pollutants from the environment, and thus, keep test samples safe.

Keeping lab workers safe: Not only the test samples but also the researchers must be safe in a lab. Air pollutants are not always harmless. They can be very dangerous for health at times. Certain important chemical reactions may generate hazardous by-products. In those cases, fine-grained effective filters are required for removing toxins. Moreover, dangerous viruses must also be kept separately from the rest of the laboratory strictly so researchers can stay out of danger while working with them. This is another reason why laminar flow workstations are crucial for a lab.

Eco-friendly and cost-effective: Laminar flow hoods can be expensive to install sometimes, but they pay for the purchase over time. By recycling air and eliminating contaminants including carbon and more, they keep the environment clean. Moreover, some laminar flow hoods run on electricity and have energy efficiency. So, they can also save power costs.

Conclusion

Laminar flow hoods are a must-buy if you take the safety of lab workers and lab samples seriously. As per your requirements, you may go for vertical or horizontal laminar flow hoods. Visit the websites of laminar flow workstation manufacturers to go through your options.
