Calamine – 500 gram Packs

Calamine is an inorganic material commonly associated with zinc oxide and ferric oxide, with the iron oxide component contributing to its characteristic pink to reddish-brown colour. It is relevant to laboratory studies involving metal oxides, inorganic mixtures, and materials characterisation. Calamine is practically insoluble in water, while its oxide components can react with mineral acids under suitable experimental conditions. Its composition makes it useful for selected investigations of inorganic chemistry, metal oxide behaviour, and analytical identification methods. This 500 gram pack is intended for laboratory sourcing, subject to confirmation of the supplied material’s composition, grade, and specifications. Because the name Calamine can refer to materials with different compositions, laboratories should verify the exact product identity before selecting it for a particular procedure. Appropriate handling and storage practices should follow the applicable safety documentation.

Why Choose Lab Wale to Buy Calamine

Lab Wale offers a sourcing option for laboratory chemicals and scientific supplies used by schools, colleges, universities, research centres, and laboratory professionals. When purchasing Calamine in a 500 gram pack, buyers should verify the product identity, applicable grade, composition, and available technical and safety information. Since Calamine can refer to materials with differing compositions, checking the specifications is important when selecting a reagent for educational or analytical work. Appropriate product selection should also consider the intended application and laboratory safety requirements.

Frequently Asked Questions About Calamine

What is Calamine in chemistry?

Calamine is a name used for certain zinc-containing materials. In some laboratory and industrial contexts, it refers to a mixture containing zinc oxide and ferric oxide, while other contexts use the name for zinc-containing minerals. The exact identity should be confirmed before assigning chemical properties or selecting a laboratory procedure.

What is the chemical formula of Calamine?

Calamine does not have one universal molecular formula when it refers to a mixture of metal oxides. In a zinc oxide and ferric oxide preparation, the principal components may be represented as ZnO and Fe₂O₃. Their proportions depend on the specific material, so a single formula mass is not applicable to the mixture.

What is the CAS number of Calamine?

CAS 8011-96-9 is associated with certain Calamine preparations. Because the name can refer to different zinc-containing materials, the identifier should be checked against the exact supplied product. This is particularly important for laboratory purchasing, chemical inventory records, and selecting suitable handling procedures.

What are the laboratory uses of Calamine?

Depending on its confirmed composition, Calamine may be considered for selected inorganic chemistry experiments, studies of metal oxides, and materials characterisation. It may also support investigations of reactions involving its constituent oxides. Its suitability depends on the analytical method, product specifications, and applicable laboratory safety requirements.

How should Calamine be stored and handled safely?

Keep the material in a tightly closed, compatible, clearly labelled container in a dry area, protected from contamination and excessive moisture. Avoid generating or inhaling dust and use appropriate gloves, protective clothing, and eye protection. Consult the applicable Safety Data Sheet for ventilation, spill management, and disposal requirements.

Storage Conditions for Calamine

Store Calamine in a tightly closed, compatible container in a dry, secure area at an appropriate ambient temperature. Protect the material from contamination and excessive moisture, and keep it clearly labelled. Avoid conditions that may disperse powder into the air. Follow the product-specific Safety Data Sheet and institutional procedures for storage and segregation from incompatible materials.

Precautions for Handling Calamine

Review the applicable Safety Data Sheet before use. Avoid generating or inhaling airborne dust and prevent unnecessary eye and skin contact. Wear suitable laboratory gloves, protective clothing, and safety glasses, and use appropriate ventilation when handling powder. Manage spills using procedures that minimise dust dispersion, and collect waste in accordance with institutional requirements. Ensure appropriate supervision in educational laboratories and avoid releasing material into drains or the environment.
