Sodium Citrate, Best Quality Laboratory Grade 

Sodium Citrate is a very useful, all-round chemical compound that can be found in scientific research, industrial processing, and even in clinical laboratories. Being recognized for its buffering capacity and anticoagulant properties, it is a necessity in labs of various disciplines. At Eng Scientific, we offer different grades of Sodium Citrate, also in various packing options, and we guarantee high purity to meet the needs of both research institutions and industrial clients. 

If you are conducting biochemical assays or are in the process of stabilizing blood samples, our Sodium Citrate will give you the same solubility, reliability, and lab-grade purity. 

What is Sodium Citrate? 

Sodium Citrate, also called trisodium citrate, is a salt of citric acid with sodium. It is a white, crystalline substance that is very soluble in water, and it gives a slightly basic solution. The compound is still at the center of the most important properties of the buffering agent, chelating agent, and anticoagulant that are the major features in medical and laboratory work. 

The compound with formula Na₃C₆H₅O₇ is a very good buffer of pH in biological and chemical systems. Depending on the need, Eng scientific offers Sodium Citrate in various grades, including analytical, laboratory, and reagent grade. 

Key properties and Benefits 

Sodium Citrate has some features and safety attributes that are perfect for the laboratory environment: 

  • Buffering Capacity to the Maximum: Holds pH unchanged in biological experiments and chemical reactions.  
  • Functionality of the Anticoagulant: Allows blood to flow without clotting in clinical and research sectors.  
  • Water Solubility: Can be smoothly combined with both water and reagent mixtures.  
  • Long Shelf Life: Holds the same quality when kept in the right storage.  
  • Variety of Grades: Lab-grade, food-grade, and industrial-grade are available (choose at checkout).  

Sodium Citrate samples are highly tested for quality and all documents like SDS and COA are provided for transparency. 

Applications of Sodium Citrate 

Sodium Citrate is the most famous additive for its adaptability and reliability in a wide range of applications: 

  • Clinical Laboratories: As an anticoagulant in blood collection tubes and for coagulation testing.  
  • Biochemistry Labs: As a buffer in enzyme reactions, DNA extractions, and PCR processes.  
  • Pharmaceuticals: It is the pH regulator and the solubility enhancer in drug formulations.  
  • Industrial Processing: It is used in cleaning agents and metal plating because of its chelating ability.  
  • Food Science: Although it is not the main point of this article, it is still worth mentioning that it is one of the most common food additives.  

If your lab requires a reliable buffering solution or a reliable anticoagulant, Sodium Citrate is a must-have item that you should always have in your stock.
