How to choose a suitable laboratory glove?
First, the damage caused by the opponents in the laboratory
● Chemical substances and stimulatory agents have an injury to handles when opening and use.
● High-temperature objects will cause burns when they are taken.
● When assembling or disassembling the glass instrument device, it is damaged to the handle.
Second, choose the six factors of laboratory gloves
● Chemical type
● Extreme temperature, low-temperature characteristics
● pH
● Physical hazard (sharp, puncture)
● Toxicity
● Potential infectious biological hazard
Selecting gloves can also refer to the safety technical manual (WSDS) involved in each chemical involved.
Third, the common gloves in the laboratory
Durable ★★★★
Torn clearance ★★★★★
Comfort and fit ★★★★
Summarize: High flexibility, fit your hands, comfortable feel. Can be used to operate organic reagents such as acetone, butanol, ethyl acetate, isopropyl alcohol, but is not recommended.
Durable ★★★★
Torn clearance ★★★★
Comfort and fit ★★★★
Summary: Dear is comfortable, easy to operate. Disposable but nitrile gloves are more common in the laboratory, suitable for most simple experiments, but some aromatic compounds and halogen-containing organic matter are not strong for many ketones.
Durable ★★★★
Torn clearance ★★★★
Comfortable and fit ★★★
Summary: gloves do not contain allergen, powder, low dust, low ion content, strong chemical corrosion capacity, almost protect all chemical dangerous goods, but organic solvents will wash off the plasticizer on gloves, in gloves "Black Caves" of different molecular sizes are generated.
Fourth, gloves use precautions
Before use
1. Before the experiment begins, you must first use a glove with sufficient protection.
2, check the gloves without small holes or damage, abrasive, especially the fingers.
3. If there is a wound, it is necessary to cure or cover the wound, prevent bacteria and chemicals from entering the blood.
Using
1. Do not drain the contaminated gloves in use, do not share gloves, share gloves can easily create cross infections.
2, don't ignore any skin of erythema or pain, dermatitis, etc.
After use
1. Extracting gloves must pay attention to the correct way to prevent contact with harmful substances contaminated on the gloves, causing secondary pollution.
2. After picking up your gloves, you should clean your hands, rub your hands, and protect your hands.
In the laboratory, the hand is an experimenter, with the highest injury rate. Experiments change a life, but pay attention in experiments, personal protective safety is the most important thing. Today, have you worn a glove?
