Laminar or Microbial Hood

Description

Introduction of Laminar or Microbial Hood

The laminar or microbial hood, which is also known as biology or microbiology, is used in cell culture and microbiology laboratories and in dealing with pathogenic agents such as bacteria, viruses, parasites, etc., as well as against other particles of pollution and dust. . Among other applications of laminar hoods, we can mention agricultural laboratories, which help in shortening the growth and reproduction time of plants and preventing the growth of agricultural pests.

The way the microbial hood works is based on air purification using an active HEPA carbon filter (high efficiency particles) and transferring one-way and clean air flow to the work environment.

Laminar hoods are divided into three different classes I, II, III based on the principles of work safety and the level of protection of the user and the laboratory sample. In the class I hood, only the personnel and the laboratory environment are protected. But in class II and III hoods, in addition to protecting the personnel and the laboratory environment from the microorganism under study, it is also protected against contamination.

How to use a microbial or laminar hood

1. Carefully open the package of the device and pay attention not to damage the device while opening the package. Carefully place the chamber on the base of the device and on the pins of the base.
2. Install the device in a clean environment and then clean the inside of the cabin and steel trays with a damp cloth and keep the cabin door closed at a distance of 2 cm from the floor.
3. Leave all the keys of the device in OFF (o) position.
4. Place the two plugs in the electrical outlet and make sure that the electrical outlet has an earthing wire and also that the two plugs are completely fixed in the electrical outlet to avoid voltage fluctuations during work.

Setting up the laminar hood

1. Put the key (MAIN SWITCH) in the ON (I) position.
2. Put the key (FLUORESCENT LIGHT) in the ON position (I) to illuminate the interior of the cabin.
3. (UV LIGHT) switch, if the environment of the cabin is polluted, turn the UV1 switch to ON, the UV lamp will be activated after 20 seconds, and after 20 minutes, it will automatically go out of the circuit, and note that people leave the room when the UV lamp is on. UV2 key is not used in this device).
   * UV HOUR COUNTER records the operating time of the UV lamp.
4. The key (FAN SWITCH) is to activate the air in the cabin. Always turn on this system 5 minutes before using the device so that all the particles inside the cabin are absorbed by the filter. After the above period has passed, the device is ready for use.
5. When using Lamin Airflow, keep the front door of the cabin up to the maximum limit, otherwise the device will give an alarm.
   Explanation 1- The smaller the distance between the machine door and the cabin table, the less likely it is to contaminate the work environment.
   Explanation 2- Install the device in a room with little traffic and note that when cleaning the room, the device should be turned off and the front door should be completely closed.
6. The device filter can be used for about 2000 to 2500 hours.
7. HOUR COUNTER is the working hours of the device to record the time of using the main filter.
8. The gas valve (butane) is installed inside the cabin with a yellow handle, which can be connected to city gas or a capsule through a rubber hose, and when using the gas valve, press the yellow handle a little and then turn it clockwise.
   **Description 1- Be sure to fix the connection hoses from city gas or capsule to the device and from the cabin valve to the consumer with a hose clamp.
   **Explanation 2- Never leave the gas light inside the cabin on when the device’s fan is off, because in this situation, the possibility of damage to the device’s main filter, which is built into the cabin ceiling, increases several times and shortens the life of the filter.
   **Explanation 3- After finishing the work, clean the cabin table and the side windows of the machine, please note: Do not use alcohol to clean the movable door in front of the machine, because it causes the front surface to become cloudy.
