Where to buy Sodium azide

Where to buy Sodium azide - Sodium azide, also known as sodium azide, is a chemical mainly used in laboratories and some industrial applications. This substance has several uses, such as in airbags, laboratory testing and as a preservative in products. However, it is important to know that sodium azide is highly toxic and can be dangerous if used incorrectly. In this article, we will discuss where to buy sodium azide, what its uses are, and what to look out for when buying it.

What is sodium azide?

Sodium azide is an inorganic compound often used as a preservative and biocide. It has the chemical formula NaN₃ and usually occurs in the form of a white powder. This substance is known for its ability to inhibit bacterial growth, which makes it useful in laboratories and in medical tests. Moreover, it is used in car airbags because of its explosive properties when heated.

Applications of Sodium azide

Sodium azide has a wide range of applications, including:

  1. Laboratories: It is often used to accelerate chemical reactions or as a biocide to kill bacteria.
  2. Medical tests: It is in the extraction fluid of corona self-tests to extend the shelf life of the tests.
  3. Automotive industry: Sodium azide is an important component of airbags because it reacts explosively when heated, which is essential for the rapid inflation of the airbag in a crash.
  4. Preservative: In low concentrations, it is used to extend the shelf life of products by inhibiting the growth of bacteria.

Where to buy sodium azide?

Buying sodium azide can be challenging because of the regulations and dangers associated with its use. Here are some tips and advice for buying this substance:

Laws and regulations

According to European legislation, specifically the REACH regulation (1907/2006/EC), sodium azide must comply with strict regulations on the use of chemicals. This means you may need a licence to buy and use this substance.

Reliable suppliers

It is crucial to buy sodium azide only from reliable suppliers who comply with regulatory requirements and can provide the appropriate safety data sheets (SDS). Some reputable suppliers are:

  • Sigma-Aldrich: This company supplies a wide range of chemicals, including sodium azide, and provides comprehensive safety information and customer support.
  • Fisher Scientific: Another major supplier of laboratory supplies offering sodium azide with detailed product information and safety guidelines.

Online marketplaces

While it may be tempting to buy sodium azide through online marketplaces such as eBay or Amazon, this is strongly discouraged. These platforms may not guarantee that the products meet safety and quality standards. Moreover, you are more likely to encounter illegal or unsafe products.

Safety measures

  1. Personal Protection: Always wear protective clothing, gloves and goggles when handling sodium azide to avoid skin and eye contact.
  2. Ventilation: Provide a well-ventilated working environment to prevent inhalation of dust or fumes.
  3. Storage: Store sodium azide in a well-sealed container away from heat sources and other chemicals that may pose a reactive hazard.

Alternative Options

If you need sodium azide for a specific project or research, consider alternative substances that are less dangerous. For example, in some laboratory applications, other biocides or preservatives may be a safer choice without compromising effectiveness.

Conclusion

Buying sodium azide requires careful consideration of laws and regulations, reliability of the supplier and adherence to strict safety measures. Make sure you are well informed about its uses and dangers before making a purchase. For further information and reliable sources, consult the websites of reputable suppliers and government agencies such as the central government.
