Product Overview
This 20% citric acid aqueous solution is an analytical reagent (AR) grade formulation designed for precision in laboratory applications. Citric acid, a weak organic acid, is widely recognized for its buffering capacity, chelating properties, and ability to maintain stable pH levels in solutions. The AR grade ensures minimal impurities, making it suitable for sensitive analytical procedures where consistency and accuracy are critical. The solution is pre-diluted to 20% concentration, eliminating the need for manual dilution and reducing the risk of errors in experimental setups. Its water-soluble nature allows for seamless integration into various aqueous systems, while its mild acidity makes it a safer alternative to stronger mineral acids for certain applications. The solution is stable under standard laboratory conditions, though it should be stored in a cool, dry place away from direct sunlight to prevent degradation. The 1000 ml pack size offers an optimal balance between sufficient quantity for repeated use and practical storage considerations.
FAQs
1. What is the shelf life of this 20% citric acid solution?
The solution remains stable for approximately 24 months from the date of manufacture when stored properly in its original sealed container at room temperature. Always check the label for the exact expiration date.
2. Can this solution be used for food or pharmaceutical applications?
While citric acid is generally recognized as safe for food use, this AR-grade solution is specifically formulated for laboratory applications and is not certified for food, pharmaceutical, or cosmetic use.
3. How should I handle spills of this solution?
For small spills, absorb with an inert material like sand or vermiculite, then neutralize with a weak base such as sodium bicarbonate before disposal. For larger spills, contain the area and follow standard laboratory spill protocols.
4. Is this solution compatible with glass containers for long-term storage?
Yes, this citric acid solution is compatible with borosilicate glass containers, which are recommended for long-term storage to prevent potential leaching or contamination from plastic containers.
5. What alternatives exist if I need a different concentration?
Citric acid is available in various concentrations and forms, including anhydrous powder and different aqueous solutions. You would need to prepare alternative concentrations manually or source pre-made solutions with the required specification.
