What is Horizontal Laminar Flow Hood? How does it work?

The Laminar Flow hoods are of two types, and these are horizontal laminar flow hood and vertical laminar flow hood. You can use them according to your needs, and there is no actual difference in the working of these both types of laminar flow hoods.

However, you need to know all the things that are associated with them, and we are here to discuss a little about the things that can help you to use the laminar flow hood to the extent. These hoods are used in the labs, and we are here to talk about the horizontal laminar flow hood. The working of the hood is really amazing, and you can get all the information in the section below.

What is Horizontal Laminar Flow Hood?

The laminar flow hood that is horizontal is in a horizontal shape, and it stands wide with all the same feature of the laminar flow hood. The thing works really great, and the thing it works for is to get the contaminant-free environment.

Well, this is not an unreal thing, and this is the actual use of these laminar flow hoods. You can get a particle free environment with the help of a laminar flow hood. This is the only use of the horizontal laminar flow hood. And the question arises why there is a need for a particle free environment? So, the answer is as follows –

Why there is a need for Particle Free Environment?

The particle free environment is really a great thing, and this is nothing less than a miracle. But you cannot be living in such a state, or you will get to see your death near. This is real, and it is true that the air around us is somehow not that good for it is not that good. You can get so many things done with the help of a particle-free nature.

So, if you are working in a lab or if some lab technician is working in the lab and the experiment needs such an environment that doesn't need any extra containment. There are many of them that cannot tolerate such a thing. So, what happens is that the laminar flow hood starts the filter and once the air is filtered out when the lab technician starts working on the project. In this way, a horizontal laminar flow hood works for you, and it is all you need. 

How laminar flow hood works?

The working principle of the laminar flow hood is really great, and if we talk about both the vertical and horizontal laminar flow hood, then the only difference is the different place for the hole. Otherwise, it works just the same, and it can help you a lot for real. The filter filters the air that doesn't let any extra particle enter through the nozzle, and it is all you need. This way it works out and helps you to get the particle-free nature for your labs.

How To Use Vacuum Desiccator Cabinets?

Desiccators are storage cabinets with dry atmosphere which contain desiccants in sealable enclosures in order to prevent moisture sensitive contents like cobalt, chloride paper for further use. It has great role in protecting those hygroscopic chemicals from humidity which reacts with water. 

In static desiccation system, there are various sizes that vary between an in-line cartridge sizes to a larger cabinet that may be nitrogen purged, or may contain a desiccant tray. Whenever the lids of the desiccators are opened, the contents inside are exposed to atmospheric moisture. Therefore, the chemicals like alkali metals, which react fast with atmospheric moisture, are not appropriate for storing. Instead, schlock-type apparatus or a glove box may be more suitable for such kind of storage.

In some cases, desiccators may even be used for removing moisture from an almost-dry sample. But when it is considered that desiccator cabinets alone will not be enough for the purpose, Abderhalden's drying pistol may be used in that case.

How vacuum desiccator works?

Desiccator cabinet works by preventing oxidation of MSD in the cabinet by controlling moisture. When a porous desiccant such as the silica gel is used by Dri-Box, it removes water from air space by multi layer absorption. The thin layers of the water molecule are attracted to the surface areas of the desiccant in that process.

It also works by the process of capillary condensation in which most of the smaller pores are filled with water.

The purpose of using the desiccator during the cooling of the crucible

In a desiccator, heated materials are cooled in order to prevent it from accumulating moistures while it gets cooled. The interior of the desiccator will remain dry as the desiccant is at the bottom, and the moisture in the atmosphere cannot enter the container as it is completely sealed.

Why are you to cool the crucible before it is weighed?

If you put the hot crucible for weighing its mass, the convection currents will start happening in the surrounding air around the crucible. That is why, whenever you need to weigh a crucible, you must let it cool first as the heat from the crucible warms the surrounding air and causes it to rise upward and then it cools down and falls.

The way of using desiccators in laboratory

Most of the laboratory desiccators are round in shape and made of heavy glass. It is usually placed on a removable platform so that it can be stored properly in a laboratory.  The desiccant, such as Silica Gel, fills the space under the platform. The color changing silica has a key role as an indicator whenever it would be refreshed. Whenever the indicator gel absorbs moisture it typically changes from blue to pink. The other colors may also be used here.

There may be a stopcock included for permitting the desiccator to be evacuated. These kinds of models are actually known as vacuum desiccator cabinet.

While applying the vacuum of a desiccator, it should be properly strapped in order to minimize the damage to the desiccator by a sudden implosion. Vacuum grease is applied here to achieve a good seal.

Horizontal Laminar Flow Hood

The Air in the Horizontal laminar flow hood is flowing horizontally, and it passes through a filter before it gets into the room. There is a pre-filter that filters the air before it gets into the laminar flow hood and it is really a great thing. This is only because of the sole purpose of using the laminar flow hood for a better and cleaner environment.

There is a HEPA filter that is joined along the pre-filter, and this is where it provides all the necessary things. It helps deep cleaning of the air, and then it gets to enter into the glass room. The Horizontal laminar flow hood helps to clear upto 97% of the unwanted bacteria, and that is a really good number.

Vertical Laminar Flow Hood

The Vertical Laminar flow hood is much expensive than the other laminar hoods. The reason behind that is that the vertical laminar flow hood helps to clear upto 99.97% of the unwanted bacteria in the glass and the experiment room. So, there is a pre-filter that is attached to the HEPA filter that again blows the air on the work surface. Unlike horizontal laminar flow hood, this type has the blower on the top in which the air flows everywhere.
