To carry out the different experiments in the laboratory the downflow hoods are quite a necessary thing. These are a part of the majority of the medical and research labs. This is included in the good lab practices. This is mainly used for killing the germs. The flow of air is in the downward direction and hence it helps in decreasing the germs. So this downflow hoods are designed in a way that the air is passed downwards and in the hoods. These are comprised of several features which make this a unique equipment and thus help in several laboratories.
What is the Downflow Hood?
Downflow hood is the equipment that is made in which there is the passage of air in the downward direction. Also, the air passed is at a particular speed or velocity and thus helps in removing the contamination. This air that comes out of the cabinet is the pure air that is devoid of the contaminants and thus helps in the easy flow of air thereby making the whole devoid of germs. This is specifically made to work in laboratories to get the experiments done in a clean environment.
How is it Made?
This is constructed in a way that comprises of the several filters and thus the cabinet. It is designed in the way that the air flows in a downward direction. The way it is made is that the filters are fitted from where the air is purified and then comes out. But it is important to know that the flow of the air is in a downward direction. It is made up of stainless steel without any gaps or leakages. If there is the presence of any gaps then there are chances of the contamination so to avoid this in the experimentation these are designed in the way to avoid this contamination and thus make the hood free from contaminants. So the special design is in such a way that it helps in doing the experiments easily and getting the exact results without any difficulties.
The Things to Be Kept in Mind While Using the Downflow Hoods
So while we are using the downflow hoods it is important to know that some of the points must be kept in mind and also that these things help us to be careful while using these types of equipment at the workplace. So the things that should be noted down while using them is listed below:1. Prefer keeping the manual aside while working. This is because it might be possible that sometimes there is difficulty in understanding some functions of the hood or sometimes the flow or the hood might not work properly. These manuals will, therefore, ensure that all the switches and the connections can be made proper. Also while installing these manuals and the booklets can help us understand the role of it.
- Before using it, it is therefore important to keep a check over the functioning of the hood. It is therefore important to keep a check as there might be some issues with connections. Before spoiling the experiment, it is better to check the things and then use them. So it is important to once make sure that the device is fully checked and proper before use.
- Reduce the number of things kept near the working place. This is important because the hoods often generate a lot of heat so it is better if the place is clean and is devoid of things. This will ensure the proper working of the hood and will give effective results without disturbing the hood as well. Often the heat generated by the hood is quite large so this should be kept in mind.
- Regular cleaning and maintenance of the hood is important. This is so because the hood is a place where the experiments are being conducted so it is important that the cleaning of the hood is an important part. Also, the maintenance is important as there are chances of the blocking so regular check of these is quite important.
- Keep the lid closed when not in use. This is because to avoid several other issues and also the contamination can be avoided. It is usually recommended to on the UV light when not in use to kill the germs and make the hood contaminant free.
So these things tell the most about the downflow hoods. Also, the heritage printing and graphics helps in getting the desired requirement about this.
