Product Overview
Potassium hydroxide (KOH) pellets from RECTAPUR® represent a high-purity GPR-grade chemical designed for demanding laboratory applications. With a minimum assay of 90%, these white, hygroscopic pellets ensure reliable performance in analytical procedures and synthesis reactions. The GPR grade designation guarantees consistent quality with low impurities, making it suitable for titration, saponification, and pH regulation. Each 1 kg pack provides sufficient quantity for repeated use while maintaining stability under proper storage conditions. The pellet form offers convenient handling and precise dosing compared to flake alternatives. As a strong base, these pellets dissolve rapidly in water with significant heat generation, requiring careful handling. The RECTAPUR® brand ensures traceable quality control, with each batch tested for heavy metals and other contaminants. This product meets international reagent standards while offering cost-effective performance for routine laboratory work.
FAQs
1. What is the difference between GPR and AR grade potassium hydroxide?
GPR grade potassium hydroxide meets general purpose requirements with slightly higher impurity tolerance compared to AR (Analytical Reagent) grade, which has stricter purity specifications for critical analytical applications.
2. Can these pellets be used for making potassium carbonate?
Yes, potassium hydroxide pellets can react with carbon dioxide to form potassium carbonate, though the process requires controlled conditions to achieve complete conversion.
3. What precautions should be taken when handling these pellets?
Always wear protective gloves, goggles, and work in a well-ventilated area as these pellets are highly corrosive and can cause severe skin burns upon contact.
4. How should these pellets be stored for long-term use?
Store in a tightly sealed container in a cool, dry place away from moisture and incompatible substances like acids to prevent degradation.
5. Are these pellets suitable for food-grade applications?
No, this GPR grade is not certified for food applications; food-grade potassium hydroxide requires specific purity certifications and manufacturing standards.
