Advantages and precautions of ultra-clean workbench


Shanghai Haozhuang Instrument Co., Ltd. developed the LNB brand ultra-clean workbench, which is energy-saving and environmentally friendly, leading the country. The advantages of the ultra-clean workbench are that it is convenient and comfortable to operate, relatively comfortable, work efficiency, short preparation time, can be operated more than 10 minutes after booting, and can basically be used at any time. In factory production, the vaccination workload is very large, and when it is necessary to work for a long time, the ultra-clean table is an ideal equipment. The ultra-clean table is powered by a three-phase motor with a blow rate of about 145 to 260W, and the air is blown out through the "super filter" layered and assembled by special microcellular foam plastic sheets, which is continuous and dust-free. The ultra-clean laminar flow of bacteria, so-called "effective special air", removes dust, fungi, bacterial spores, etc. that are 0.3 μm large. The flow rate of ultra-clean air is 24 ~ 30m / min, which is enough to prevent the pollution caused by the possible disturbance of nearby air. Such a flow rate will not prevent the use of alcohol lamps or Bunsen burners to burn and disinfect instruments. The staff operates under such sterile conditions to keep the sterile materials free from contamination during the transfer inoculation. However, in the event of a power outage in the middle of the operation, materials exposed to unfiltered air will not be spared pollution. At this time, the work should be ended quickly, and a mark should be made on the bottle. If the material inside is in the multiplication stage, it will no longer be used for multiplication and transferred to rooting culture in the future. If it is a general production material, it can be discarded because it is extremely abundant. If it is rooted, it can be used for planting later. The ultra-clean workbench can be used as a filter to prevent bacteria from leaving the air unpolluted, and its easy operation allows us to save a lot of time and trouble.

The application of ultra-clean workbench The 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 appeared 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.

Classification of ultra-clean workbench 1. According to the direction of airflow, 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; . 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.

The products are made of PU sponge which is super soft. It simply makes dirt disappear and brings lots of conveniences to you. Good absorbing of water, no additional detergents needed while using. Macroporous structure can produce rich foam in a short time, make your clean more easily. Absorb water with sponge and squeeze out gently. Gently rub sponge on dirty surface to remove the dirts and smudges. Rinse the dirty sponge with water after use and dry it. Dispose of properly after multiple uses It can be used with different sizes by cutting with knife or scissors according to purpose. Widely used as a cleaning material in Household Cleaning, Car Washing. etc. Car Cleaning Sponge, bulk sponge, Car Sponge, car polish wax, heavy duty Cleaning Sponge, foam cleaning sponge.
