Laminar Air Flow is an enclosed unit and installed to create a contamination-free work Environment. This unit comes with installed filters that are designed to capture all the dust and other particles entering the cabinet or the workstation.
This product has been designed to provide a safe working environment by keeping it clean from contaminants. These cabinets are useful for the aseptic distribution of a specific plate pouring. The cabinets are similar to other types of cabinets including biosafety cabinets.
The only difference these cabinets have over others is that the air through these units is drawn directly to the user’s face. However, in the case of the biosafety cabinet, the samples, as well as the users, are protected. But the laminar flow cabinets only protect the sample.
Here are the components of the Laminar Flow Cabinet:
- Working station
- Filter pad/ Pre-filter
- Fan/ Blower
- UV lamp
- Fluorescent lamp
- HEPA filter
How do These Cabinets work?
The laminar flow cabinet works by the utilization of an inwards stream of air through at least one HEPA filter. This is done to create a particle-free environment. The air is taken through a filtration framework and afterward exhausted across the work surface as a part of the device.
The process begins with air entering into the pre-filter that starts a smooth out the progression of air into the cabinet. Once done, the blower directs the air to the HEPA filters. These filters are designed in a manner that they trap all kinds of microorganisms, parasites, and particles. The air that comes out of these filters is free from all these particles.
The whole structure of this device is enclosed in a sealed container. It prevents that contaminated air from entering back into the chambers.
How to operate laminar Flow Cabinets?
- At first, you must ensure that there is nothing present in the device that is vulnerable to UV rays.
- Once the glass sheet is closed, UV light must be kept on for at least 15 minutes to sterilize the surface of the workbench.
- After switching off the UV light, a 10 minutes gap should be maintained before beginning the airflow into the chambers.
- Now as the airflow is switched on, the glass shield is opened and the fluorescent light is switched on.
- For an extra layer of protection, the working bench of the device can be further sterilized with materials like alcohol (70%), etc.
- Once all the necessary steps have been taken, the glass shield is closed along with the airflow and fluorescent lamp.
