Talk about the necessary characteristics of laboratory gloves, do you know a few?

China's Laboratory Biosafety Management System clearly stipulates that laboratory personnel should wear gloves when operating samples and cultures that may be infectious. So what kind of gloves would be appropriate to ensure the health of lab workers?

1. Gloves should be used for isolation and protection

In each experiment, workers were often exposed to various living creatures or reagents, such as dissecting mice, to build biological models; Or culture all kinds of bacteria and organisms to express protein and extract plasmid; Or contact chemical reagents to prepare the required reagents, etc. During these operations, disposable gloves with excellent isolation are required to protect laboratory personnel from hand safety. Disposable nitrile gloves and medical latex gloves are good choices for laboratory supplies. In the laboratory, especially the chemical laboratory, many chemical reagents have a certain corrosive, will cause irritation and harm to the skin. Therefore, laboratory personnel's gloves must be able to have a certain chemical resistance, in order to ensure personal safety.

There are many types of disposable gloves on the market. It is not recommended to use PVC or PE gloves in chemical laboratories, but nitrile or medical latex gloves. Nitrile gloves have better chemical resistance than latex gloves. It is the regular consumables in the laboratory. Nitrile gloves are not only superior to latex gloves in chemical resistance, but also superior in hand flexibility.

2. Gloves have puncture resistance and tear resistance

There are many glassware in the laboratory. If the glassware is broken when assembling or disassembling the glassware, it is easy to cut the hand. Wearing a pair of piercing and tearing resistant protective gloves creates a protective barrier between fragile skin and hard glass. Even when dealing with broken glass, there is no need to worry about scratches on the hand, avoiding subsequent wound infection and other problems.

Experimenters often contact with all kinds of precise and fine instruments. If the sensitivity and flexibility of hands cannot be guaranteed by gloves, the efficiency of the experiment will be affected, and even the experimental results will have a large error. Hole-in-the-wall gloves are made with advanced technology to make the wearer feel like a second layer of skin. Moreover, nitrile gloves can remember hand movements and will not feel tired even if worn for a long time. The experimental efficiency and accuracy of experimental results are guaranteed.

3. Gloves should provide grip strength

Glassware and most experimental equipment have smooth surfaces and are not easy to grasp. Choose disposable gloves with full hemp, palm or fingertip hemp to solve the problem. Gloves with hemp can provide a good grip and prevent the instrument from slipping, causing unnecessary loss or injury.

Now, let's review the five essential characteristics of experimental gloves: isolation, flexibility and sensitivity of the hands, puncture resistance and tear resistance, and improved grip strength. Did you GET it?
