For decades, the chemical industry has relied on traditional marketing tactics to reach a wide range of consumers. روز مواد شیمیایی صنعتی irchem.ir Fortunately, online platforms have made it much easier to sell chemicals and their products to customers.
Purchasing laboratory-grade chemicals
When purchasing chemicals for a science fair project, you should look for lab-grade brands. These products are generally not sold locally, and you will need to buy them from a reputable chemical supply company. Some chemical suppliers are accredited by Science Buddies, and you can also purchase these products from an online distributor. For example, the chemicals Drano and 20 Mule Team are both approved by Science Buddies.
When selecting a chemical, you should also consider the purity level. Reagent-grade chemicals are more pure, and they are suitable for general laboratory use. Crude-grade chemicals, on the other hand, have a high purity, but don't meet the published standards for quality. For example, iodine labelled as "crude" has a purity level of 99.5%, but does not meet standards established by the American Chemical Society (ACS). Moreover, they are less expensive, but they are often used for less-critical analyses and for educational labs.
Purchasing industrial raw materials
There are many factors to consider when purchasing industrial raw materials. Whether you are making a new product or modifying an existing one, it is imperative to purchase the right raw materials. These materials can be obtained from many sources, and they can vary in grade, concentration, and form. Even minor variations in batch characteristics can lead to significant cost differences. This makes procurement difficult, especially for specialty chemicals. Fortunately, modern procurement tools such as SAP Ariba have come a long way to simplify the process.
The first step in implementing a good purchasing strategy is identifying strategic products and determining what types are needed. Depending on the complexity of the chemical, a company can spend anywhere from one to 20 percent of its total revenue on the product. In addition, it may be necessary to purchase various grades of a single chemical, as the slightest change can affect the processing cost dramatically. As a result, chemical purchasing must be backed by a robust management process.
Purchasing restricted materials
When purchasing chemicals, it is important to remember that there are strict regulations governing the sale of chemicals. Some chemicals have restrictions on their shelf life, expiration dates, and handling. Additionally, some chemicals must be stored in closed systems, making it necessary to know all the safety precautions and requirements before purchasing. If possible, you should also look for alternatives to restricted materials.
To learn more about substances on the restricted list, check the ECHA database. These substances can be dangerous for humans or the environment. Fortunately, you can usually find a substitute for these substances, such as a safer, non-restricted alternative.
