Make your experimental career longer guide to choosing laboratory safety protection equipment

No matter the teachers and students in the university laboratory or the researchers who stay in the laboratory all the year round, they all know the importance of experimental safety Even Fudan University and Tsinghua University have had serious laboratory safety accidents, which is a wake-up call to our laboratory safety Laboratory is different from other places There are not only various scientific phenomena, but also safety accidents caused by subjective or objective factors In order to make your experimental life longer, it is necessary to use qualified safety protective equipment to ensure basic personal health and safety Guide for purchasing laboratory protective equipment: when entering the laboratory, we will generally put on suitable shoes, white coats, masks, gloves and goggles, and sometimes use laboratory protective covers 1 In general, except for laboratories with special requirements, there are no rigid regulations for changing shoes in laboratories, which are ignored here If shoe cover is needed, it is recommended as follows: bright disposable polyethylene shoe cover 2 White coat is not only a symbol of occupation, but also has the function of isolation and protection A good white gown requires good texture of fabric, exquisite workmanship, elegant appearance, no pilling, sweat absorption and ventilation, comfortable wearing, and can also be added with conductive fiber and other auxiliary functions as required Note: the white gown should be changed and cleaned regularly, which is different from the disposable isolation suit in the hospital 3 If the laboratory is not well ventilated, it will smell a special smell In the experiment, irritating harmful substances are often produced, which will cause harm to our respiratory system Therefore, we need to wear the protective equipment of filtering gas mask, which is usually used once If the experiment time is long, it is recommended to replace it as appropriate to avoid failure or even reaction The masks must be comfortable and practical, and the masks required by different experimental environments are different Generally, non-woven or activated carbon masks can be worn in the laboratory; 3M dust masks with good sealing performance can be selected when odor or dust particles are involved in the experiment; of course, gas masks must be worn when odor or toxicity are involved in the laboratory Common masks are recommended as follows: Guangming disposable non-woven mask as one / asuiwang active carbon stereo mask MEDICOM active carbon disposable mask MEDICOM disposable male and female mask anti dust and anti fog MEDICOM N95 three-layer filter cup mask 4 The experiment can't be done without eyes and hands, and we can't ignore the safety protection of both because it's not painful During the experiment, we often encounter some emergencies, such as sample splashing, which may hurt our eyes Good protective glasses should not only protect the eyes and have a certain anti impact ability, but also ensure that the changes of experimental phenomena can be observed clearly In case of sudden heat and sudden cold, they will not atomize and are not easy to be corroded by organic solvents Five star recommends MEDICOM's imported high transmittance and anti fog glasses, which can be easily used even when wearing glasses In addition, eye washer should be installed in the laboratory If any chemical solvent splashes into the eyes, it should be rinsed thoroughly with eye washer immediately, and then treated with one eye Reminder: the price of eye wash recommended here needs to be asked! In addition, if there are obvious rebound debris and solvent splash in the experiment, it is recommended to use the experimental protective cover The laboratory protective cover is a curved shape, which provides a certain degree of protection The protective cover uses 6mm thick acrylic or polycarbonate as the protective material, and the lower end angle is customized with 304 stainless steel The finger hole on the top of the protective cover is more convenient to move, There is a handle on the lower end, which can effectively isolate the rebound debris and solvent splash This is a necessary safety protection equipment, and the protective cover does not provide radiation protection Five Especially be careful of the contact between the skin and chemicals in the experiment, especially the strong acid, strong alkali and strong corrosive reagents Pay special attention to the isolation Some severe reagents may even melt a thin layer of gloves How can you imagine the direct contact skin? Once you saw someone asking for help in the stick bar, for example, what to do if the eyes are accidentally splashed by the solvent, and the hands are corroded by the strong acid I believe that this person will not take the safety protection of the laboratory lightly in the future How to deal with this is not mentioned here, only a few good laboratory gloves are recommended Youligdingrui powder free latex gloves bright disposable non slip polyethylene (CPE) gloves thickened ammex IMAS Disposable Nitrile Gloves MEDICOM madicon Disposable Nitrile Rubber thickened gloves Sometimes it is more helpful to choose gloves flexibly for the safety protection of the experiment According to the reagents used in the experiment, gloves made of materials that are not easy to be corroded can be selected Even disposable transparent PVC gloves can be worn on the inner layer, and a pair of gloves can be worn on the outside The above is the guide to purchase laboratory protective equipment presented to you in this issue For more good laboratory equipment, please go to CBG online store to search by yourself, or send the demand to customer service Scientific research is not completed in a day, and the experiment career can not be ended without gloves Use the experimental safety protective equipment well and love yourself better.
