Maintenance

1. The correct way to keep chemicals in the lab is always one of the most important issues. The chemicals that are kept together in the wrong way may react with each other and produce dangerous products. Occasionally, improper containment of chemicals, in addition to contamination, causes waste of materials and decreases the properties and effects of chemicals.

2. The following points can eliminate the dangers of material incompatibility.
Avoid keeping acids in the vicinity of active bases or metals such as sodium-potassium and magnesium.
Avoid storing solids or oxidizing agents in the vicinity of organic acids and flammable materials.
Avoid storing substances that react with water around a washbasin sink or near aqueous solutions.
Avoid storing acids in the vicinity of substances that are in contact with toxic gases (such as sodium cyanide-sulfide).

3. The following table lists the names of a number of chemicals that are incompatible with each other and should not be adjacent to each other.

News

Significant retailers and consumers of laboratory chemicals

It is reported recently that some profitable people, by forging names, labels and containers of the chemical industry complex Dr. Majli, have been distributing widespread counterfeit products, which is being pursued by the relevant authorities.
Obviously any distribution and sale of these products is a violation and will be treated in accordance with the law.
Consumers and associates are requested to inform the law enforcement agencies or the company if they are aware.

Thanks
