A laminar airflow chamber is an enclosed cabinet equipped with a HEPA (High-Efficiency Particulate Air) that provides uniform flow in both direction and velocity. This cabinet provides an aseptic movement to perform various experiments. A laminar airflow cabinet spreads unidirectional airflow with little or no turbulence at a uniform speed ranging between 0.3 to 0.5 m/s. This cabinet is extensively used in various laboratories to maintain an aseptic or contaminant-free working atmosphere.
As a renowned laminar airflow chamber manufacturer in Punjab, Genist Technocracy Pvt. Ltd., has provided these airflow chambers to various laboratories and industrial businesses to fulfill their needs. If you are planning to buy one, they can be your first choice regarding this.
Various types of laminar airflow cabinets –
The two categories of laminar airflow cabinets are distinguished by their respective set of features and are outlined below:
Vertical laminar airflow – This airflow cabinet is one of the more common types. In this cabinet, air flows from top to bottom. Here, the blower and the filter are staged on the top of the device. The air flows out from the front of the enclosure after hitting the work surface.
Horizontal laminar airflow – This type is relatively spacious and large and has the HEPA filter mounts back of the cabinet. Generally, airflow is from back to front and can’t function if the front glass sash is not opened. The pre-filter draws air from the front of the box, where it is located, and is situated beneath the work surface. While on the other hand, the blower is located at the bottom of the airflow cabinet.
Usage of laminar airflow cabinet –
Researchers in bioscience labs often need to work with sensitive cultures and other things that are very sensitive to things floating in the air.
Will you want that in your previous culture? No.
If you need to keep your operation safe from these airborne contaminants, you must work only in a sterile, filtered air environment.
Also, the airflow has to be laminar, as normal airflow is in a very uneven pattern. Turbulent airflow scans generate a lot of eddies and vortices that wreak away havoc on any sterile-air environment. Normal airflow gathers and deposits particles from outside air on your hard-worked culture and distorts the entire result.
As a result, the airspace over the working area flows as a unit in a straight line, preventing the formation of eddies and vortices. That is precisely what laminar airflow is.
Various parts of a laminar airflow cabinet –
An example of a laminar airflow cabinet and its parts are listed below:
Enclosure – This is a container that controls the sterile conditions in the large room. This enclosure is a cube-shaped box made of stainless steel, sealed off from the outside world by a glass shutter to maintain the sterile conditions inside the airflow cabinet. This box is often made of stainless steel, as it is very resistant to biological contamination and is easy to clean without needing any special coating as such.
Work surface – Also made of stainless steel, this is a flat table for you to work on inside the enclosure. If it is a vertical laminar airflow, the work surface must have holes to let the air pass through. You require your work apparatus on this surface to carry out sensitive tasks like tissue culture, electronic wafer formation, bacterial culture, and more. It is resistant to biological contaminants, is easy to disinfect, and does not need any special coating. It is also robust and will support any lab equipment you use in a microbiology lab.
Filter pad – This is positioned on the top of the laminar airflow cabinet that filter traps microbes and dust particles from entering the working space within the cabinet.
Fan or blower – This is the actual machine responsible for the airflow. The air is sucked in through the pre-filter and forced through the HEPA filter by a fan or blower. It regulates airflow and is located between the filter pads. This can come in various shapes and sizes depending upon models and in different powers as well.
HEPA filter – This is one of the most critical parts of laminar airflow. This is positioned next to the enclosure, separated by a mesh. If the device is a horizontal airflow type, then the HEPA filter will be at the back of the cabinet. In case the airflow type is vertical, it will be placed on the top of the enclosure.
UV lamp – While the HEPA filter can’t supply quite well-filtered air, it isn’t completely sterile. Only a certain amount of microns gets passed through the filter, and some external sir somehow gets in. Even though surfaces of the enclosure and work areas can have some microbes stuck, using merely air pressure will not suffice; so, we must instead employ a “killer ray” to eradicate them. The UV lamp radiates ultraviolet light, which cleans them out, causes cells to grow unnaturally, and destroys living proteins. Beakers, test tubes, Petri dishes, and other glassware and plasticware can be disinfected by placing them on the workbench in the UV light. This is in addition to the sterilization of the air and surfaces inside the enclosure.
So, a laminar airflow chamber is handy in various lab furniture and instrument when you need to do some sensitive work that even the outside air can damage it. This airflow chamber provides a sterile, clean atmosphere inside the cabinet where you can work with sensitive materials like tissue culture or electronic wafers.
