Clean bench purchase and design

In the 21st century, the development of science and technology is inseparable from the tools of research. It is inseparable from the cleverness of human beings. In many laboratory equipment, the clean workbench is now in biopharmaceutical, biological science, medical science, food safety, food manufacturing. It has become an indispensable experimental equipment in the fields of production and electronic science. Research staff need a clean bench to provide a clean and dust-free laboratory environment to protect expensive samples and dangerous samples from contamination, leakage, and damage to nearby environments. The clean bench can meet the research staff's test environment. Requirements.

Clean workbench purchase

At present, various brands and models of clean workbench on the market, consumers do not know how to choose when they are shopping, dazzling. How can I choose the clean bench that I need to meet the requirements of the experiment? How can we make the most of the clean workbench? Some purchase suggestions are for your reference.

2. Regardless of how good the sales staff is to clean the workbench, you must consult the fan of the clean and clean workbench (vertical air supply, horizontal air supply) and filter. These two products represent the technical level of the product in the industry. It is impossible to make a fake. The technical level of fans and high-efficiency air filters in the country is much worse than that of foreign products. Therefore, high-end products produced in the country generally use inlet filters and fans.

3. Because countries have different scales for filter definitions and test methods, so at the time of purchase, you can ask suppliers to provide filtration efficiency data similar to those of filters with higher filtration efficiency. The smaller the filter capture efficiency, the better the filter function. It should be noted that the internationally accepted test method is photon counting, and the commonly used test method in the country is the sodium flame method. In this regard, please choose the appropriate clean bench according to your needs.

4. Compare goods, service, quality, after-sales, brand, word of mouth, so that you can buy more reliable products.

Clean bench - optical design

Maybe you think it's very simple, it looks very bright, and it looks clear inside. If you are a purchasing staff, you can often watch it for a few seconds, and the operator may have to concentrate on the sample for hours in such a light. If the light source design is unfair, they will soon get tired. of. So you have to pay attention: the light in the cabinet is not too bright. If the experiment staff needs strong light, it is not enough to rely on a few fluorescent tubes. They will prepare the light source themselves. The fluorescent lamps should not directly illuminate the eyes of the operator. You can manipulate them like this. The staff sit in front of the clean workbench, how to see if you can see the fluorescent lamp clearly; many suppliers like to make the stainless steel work surface and the inner cavity bright as a mirror to advertise their products clean, but this may It is just that the light is directly reflected into the eyes of the operator, which is unfavorable for use, so you should not clearly see the shadow of the fluorescent lamp on the work surface when you are in the position of manipulating the staff.
