Structure and operation specifications of ultra-clean workbench

Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle

Factory direct sales - solid capacitor - patch aluminum electrolysis, to ensure that the factory first-class goods!

The ultra-clean workbench is a kind of partial purification equipment, which uses air clean technology to make the space in a certain operation area reach a relatively dust-free and sterilized state, mainly composed of three parts: an air filter device, an ultraviolet sterilizer, and a console.

Characteristics

1. It can be used to switch between two airflow directions, horizontal flow and vertical flow under different process requirements.

2, using adjustable air volume fan system, light touch switch and stepless adjustment voltage. Ensure that the wind speed in the work area is always ideal.

working principle

The air is sucked into the pre-filter through the fan, and the high-efficiency filter is filtered through the static pressure box, and the filtered air is sent out in a vertical or horizontal airflow state, so that the operation area reaches 100-level cleanliness, and the requirements for environmental cleanliness are ensured. . The ultra-clean workbench is divided into a vertical flow ultra-clean workbench and a horizontal flow ultra-clean workbench according to the direction of the airflow. According to the operation structure, it is divided into two types: unilateral operation and bilateral operation. According to its application, it can be divided into ordinary super-clean work. Taiwan and biological (medicine) ultra-clean workbench.

Operating specifications:

Steps:

1

,

Check the operating environment of the clean bench, such as ambient temperature, air quality, power supply, etc., to register usage information;

2

,

Place the equipment required for the experiment on the surface of the ultra-clean workbench, place the material that has been sterilized, such as the culture medium, on the left side, and place the tool on the right side;

3

,

Pull down the glass baffle and turn on the UV lamp for 30 minutes for surface sterilization;

4

,

After 30 minutes, turn off the UV lamp, turn on the fan to adjust to the appropriate air volume, and turn on the light;

5

,

Open the glass baffle to a height of about 20cm. Both hands can be operated smoothly in the console, and wipe the hands and countertops with 75% alcohol;

6

,

Ignite the alcohol lamp, the operation process strictly follows the aseptic operation specification;

7

,

After the operation is completed, the laboratory equipment is cleaned out of the aseptic operating table, 75% alcohol is used to wipe the countertop, and the lighting, fan and baffle are turned off.

8

,

Turn off the UV lamp after turning on the UV lamp for 15 minutes.

Precautions:

1, it is strictly prohibited to store items for a long time in the ultra-clean workbench;

2, ultraviolet rays are very irritating to the skin and retina, avoiding direct ultraviolet rays, and single-layer glass can effectively block ultraviolet rays;

3, the operation process should strictly abide by the aseptic operation specifications;

4, to avoid frequent switching of UV lamps and lighting tubes, to extend the life of the lamps;

5, regularly check the air filter and other filter materials, aging should be replaced.
