EDTA solution 500ml | Biorays


EDTA (Ethylenediaminetetraacetic acid) solution is a versatile chemical solution commonly used in various laboratory applications and industries. It is a chelating agent that forms stable complexes with metal ions, making it valuable for a range of purposes, including sample preservation, metal ion removal, and as an anticoagulant in medical settings.

The key features and uses of EDTA solution include:

  1. Chelating Agent: EDTA is a powerful chelating agent that forms stable complexes with metal ions by binding to them. This property is particularly useful in various applications where the removal or sequestration of metal ions is required, such as water treatment, food preservation, and chemical analysis.

  2. Sample Preservation: In laboratories, EDTA solution is often used as a preservative for biological samples and specimens. It helps to inhibit the activity of enzymes that can degrade DNA, RNA, or proteins. By chelating metal ions that may catalyze enzymatic reactions, EDTA helps preserve the integrity of biological samples and maintain their quality for subsequent analysis.

  3. Metal Ion Removal: EDTA solution is widely employed in analytical chemistry for the removal of unwanted metal ions from solutions. It can selectively bind to and remove metal ions, such as calcium, magnesium, iron, and copper, which can interfere with analytical measurements or cause undesired reactions. This makes EDTA a crucial reagent for sample preparation in various analytical techniques.

  4. Anticoagulant in Medical Settings: In medical settings, EDTA solution is used as an anticoagulant for blood collection. It prevents the clotting of blood by chelating calcium ions, which are essential for the clotting process. EDTA is commonly employed as an anticoagulant in hematology laboratories for blood cell counting and analysis.

  5. Metal Ion Complexometric Titrations: EDTA solution is an integral part of complexometric titrations, a technique used to determine the concentration of metal ions in solution. In this process, EDTA is added to the solution containing the metal ion of interest, forming a complex with the metal. The endpoint of the titration is typically detected using a color change indicator.

  6. Cleaning and Disinfection: EDTA solution is utilized in cleaning and disinfection processes, especially for removing stubborn mineral deposits or scaling caused by hard water. Its ability to chelate metal ions helps dissolve and remove calcium, magnesium, and other mineral deposits from various surfaces and equipment.

EDTA solution is typically prepared as a stable aqueous solution with a specific concentration depending on the intended application.
