Shanghai Haozhuang Instrument Co., Ltd. Haozhuang (LNB) brand ultra-clean workbench has become an indispensable laboratory equipment in the research fields of medicine, biological science, food science and electronic science. Scientists need ultra-clean workbenches to provide a clean, dust-free test environment to protect expensive samples from contamination and dangerous samples from leaking into the surrounding environment. The ultra-clean workbench independently developed by our company (Shanghai Haozhuang Instrument Co., Ltd.) has emerged to meet the requirements of users in this regard. The working principle of the ultra-clean workbench The ultra-clean workbench is designed to meet the needs of the cleanliness of the local work area in the fields of modern industry, optoelectronic industry, biopharmaceuticals, scientific research and testing. Its working principle is: the air is sucked through the fan, filtered through the static pressure box through the high-efficiency filter, and the filtered clean air is sent out in the state of vertical or horizontal air flow, so that the operation area continues to reach 100 grade cleanliness under the control of clean air Degree to ensure that the production requires environmental cleanliness.
Application of Shanghai Haozhuang Instrument Ultra-clean Workbench:
1. According to the direction of air flow, it is divided into vertical flow ultra-clean workbench and horizontal flow ultra-clean workbench. Vertical flow workbench is mostly used in medical engineering to ensure human health; horizontal flow workbench is mostly used in electronics industry.
2. According to the operation structure, it can be divided into unilateral operation and bilateral operation.
3. According to its purpose, it can be divided into ordinary ultra-clean workbench and biological (medicine) ultra-clean workbench.
4. According to the number of operators, it can be divided into single ultra-clean table and double ultra-clean table;
5. According to the structure, it can be divided into two types: downward suction and upward suction.
6. According to the air supply, it can be divided into horizontal air supply and vertical air supply.
Technical standard of biological (medical) ultra-clean workbench
1. Biological operation configuration: the bottom of the workbench is equipped with a sewage outlet, and the exhaust place is set> high efficiency filter.
2. Full-circulation airflow design, when a large amount of fresh air is added to the work area, part of the return air can be discharged from the top exhaust vent.
3. Spring type up and down sliding doors are equipped at the front and back of the working table, which is flexible and convenient even for positioning.
4. Air curtain isolation design to prevent cross contamination inside and outside.
5. Equipped with 2KW spare socket to provide convenience for the operator.
6. The use of low-noise and high-efficiency centrifugal fan has the advantages of low noise, low vibration and stepless speed regulation during operation.
7. The unique return air design of the biological clean bench can meet the strict cleaning requirements of the dust particles and colony counts in the pharmaceutical and pharmaceutical industries; it is equipped with a spring-type up and down moving door or a counterweight moving door, which is flexible and convenient for positioning.
8. The split design of the vertical table and the box body minimizes the impact of vibration.
9. The whole box body is made of high-quality cold rolled steel plate, the surface is electrostatically sprayed (stainless steel), and the work surface is made of sanded stainless steel plate. 10. The wind speed is controlled at about 0.42m / s.
11. Adopting two stages of initial high-efficiency filtration, the initial efficiency filtration efficiency is G4, high-efficiency filtration efficiency, purification level 100 (US Federal Standard 209E)
12. Airflow direction: vertical air supply from top to bottom.
13. All products are shipped out in accordance with the US Federal Standard 209E, and have high reliability. Features and advantages of ultra-clean workbench
Common ultra-clean workbench structure
1. The outer shell is made of high-quality cold-rolled steel plate by bending and welding, and the surface is treated with anti-rust treatment to be painted, which is beautiful and durable.
2. The primary effect filter is set at the top / rear of the workbench, and the filter material is made of high-quality non-woven fabric, which has excellent breathability and filtration performance.
3. The high-efficiency filter is composed of long-fiber filter paper and outer frame, which has the characteristics of low initial resistance, large dust holding capacity, high filtration efficiency (99.99%), long service life and easy replacement.
4. The speed of the fan can be adjusted by using the table controller to obtain different air volume. Illumination lamp and germicidal lamp can be controlled separately.
5. The workbench uses an ultraviolet lamp to realize the sterilization function. The ultraviolet lamp can emit strong ultraviolet rays with a wavelength of 2537A, which can not only kill living cells of microorganisms, but also have strong heat resistance to spores (such as Bacillus subtilis spores) and other bacteria Spores, mold spores, etc. can all kill. In addition, it also has a rapid destruction effect on phages and viruses.
