Product Overview
Hydrofluoric acid (HF), at 40% concentration and LR grade, is a highly corrosive and reactive mineral acid widely used in laboratory settings. Known for its ability to dissolve glass and metal oxides, it is a critical reagent in etching processes, surface cleaning, and chemical synthesis. The LR (Laboratory Reagent) grade ensures high purity and consistency, making it suitable for precise applications where impurities could compromise results. Due to its hazardous nature, proper handling, storage, and disposal are essential. This acid reacts with silica-based materials, making it indispensable in specialized chemical procedures. Always use with appropriate safety measures, including protective gear and ventilation, to prevent exposure. Its versatility extends to industrial and research applications, where controlled reactions are required. Store in tightly sealed containers away from incompatible substances to maintain stability and safety.
FAQs
1. What precautions should be taken while handling 40% hydrofluoric acid?
Always wear chemical-resistant gloves, goggles, and a lab coat. Work in a fume hood or well-ventilated area to avoid inhalation. Neutralize spills immediately with calcium gluconate gel and seek medical attention if exposed.
2. Is this hydrofluoric acid compatible with glass containers?
No, hydrofluoric acid reacts with silica-based materials like glass. Store and handle it in polyethylene or Teflon containers to prevent corrosion and leakage.
3. What is the shelf life of 40% hydrofluoric acid?
When stored properly in a cool, dry place and tightly sealed, hydrofluoric acid remains stable for up to 2 years. Avoid exposure to moisture or air to prevent degradation.
4. Can this acid be diluted for less concentrated applications?
Yes, but dilution must be done carefully by adding acid to water slowly to prevent violent reactions. Use appropriate protective equipment and follow standard lab protocols.
5. How should spills of hydrofluoric acid be managed?
Contain the spill with an inert absorbent like sand, then neutralize with calcium carbonate or lime. Avoid direct contact and dispose of waste according to local hazardous waste regulations.
