In various medical and pharmaceutical laboratories, you will find a laminar flow cabinet. Such cabinets are used for conducting experiments on bacteria, virus, antigen, and many other molecular substances. Since these are sensitive materials, you need to protect them from contamination. If those samples get contaminated, result of the experiments will become confusing. For protecting such materials from contamination, laminar flow cabinet has been used. Regular cleaning should be the integral part of such laboratory equipment. For cleaning them, you can follow the tips discussed in the following section.
Three Types of Cleaning
For cleaning the laminar flow cabinets, you need to use three types of techniques. These methods are disinfecting, sanitizing, and sterilizing. These three levels of cleaning should be performed for accurately cleaning the laminar flow cabinets.
Sanitization: Sanitization has been regarded as the standard process of cleaning laboratory equipment. Through such cleaning process, you remove the visible objects, like dirt, dust, patch marks, etc. It also helps reducing germs from the surface of the laminar flow cabinets.
Disinfecting: The second stage is disinfecting. In such cleaning process, virus, bacteria, and other harmful microorganisms are removed from the surfaces of laminar flow cabinets. Germs that do not get omitted after sanitization can be cleaned using this method.
Sterilization: Such cleaning method is conducted through heat, chemical, and pressure. You can remove all sorts of germs through this process. It is the most reliable method of omitting harmful microorganisms from the laminar flow cabinets.
For cleaning the laminar flow cabinets, you need to keep the material of the cabinet in mind. Various chemicals can react with the material of the cabinet. As a result, the laminar flow cabinet will get damaged. You need to use a chemical that is non-reactive with the material of your laminar cabinet.
Get Ready with the Cleaning Accessories
At the time of cleaning laboratory flow cabinets, you need to follow some safety measures. If you do not follow the safety guidelines, you will end up finding many problems. It can also lead to potential health hazard. In the following section, you will find the list of the cleaning accessories required for the cleaning of laminar flow cabinet.
Gloves: Wearing clean room gloves is essential for cleaning the laminar flow cabinets. It will prevent direct contact with virus, bacteria, and other harmful microorganisms. At the same time, it will help to avoid direct chemical contact with your hand. Some chemicals have harsh effects on human skins.
Garbage Bag: You need to have a garbage bag for collecting all the items that are not required. Waste materials should be put into the garbage bag. Make sure that you dispose the bag safely.
Paper Towels: For cleaning the wet surfaces, using paper towels is a good thing. You can easily clean the wet surfaces with paper towel. Nevertheless, you can dispose them easily after cleaning.
Vacuum Cleaner: For removing large particles of dust or dirt, you must use a vacuum cleaner. Rubbing surfaces with large particles will lead to scratches on the surfaces of laminar cabinets.
Cleaning Vertical and Horizontal Flow Cabinets
Vertical and horizontal flow cabinets feature different mechanisms for emitting airflow. Vertical system comes with filters and fans at the ceiling of the cabinet. You may need a ladder for cleaning the filters and fans. Not only cleaning, the filters should be replaced periodically. Fans are not required to be replaced, unless they start malfunctioning. But, fans should be cleaned frequently for good airflow and durable performance. For horizontal flow cabinets, you do not need a ladder. You can easily access the filters and fans. It is easy to clean them regularly. Moreover, changing filter can happen within a few minutes.
Other Methods of Cleaning
For sterilization of the airflow cabinets in medical laboratories, you can use dispersed vaporized hydrogen peroxide particles. They float around the room and settle on different surfaces. When they settle on a surface, they kill germs and harmful microorganisms on the surface. For cleaning process, mops are not needed. The process involves lesser human efforts. As a result, it is convenient, cost-effective, and lesser time-consuming. Apart from this, there is another way of conducting sterilization process. The way is known as UVC sterilization. It can also remove germs efficiently from the surface of laminar flow cabinets.
