Product Overview
Sodium tetraborate decahydrate, commonly known as borax, is a high-purity (99.5%) analytical reagent designed for laboratory applications requiring precision and consistency. This crystalline powder dissolves readily in water, forming a stable alkaline solution that serves as an effective pH buffer in biochemical and chemical processes. Its well-defined composition ensures reliable results in titration, flame retardancy testing, and synthesis reactions. The decahydrate form provides a consistent water content, eliminating variability in experimental outcomes. As an analysis-grade chemical, it meets stringent quality standards, making it ideal for quantitative analysis where accuracy is critical. The compound’s low toxicity and high stability further enhance its suitability for controlled laboratory environments. Whether used in volumetric analysis or as a flux in metallurgy, this sodium tetraborate variant delivers reproducible performance, reducing the risk of experimental errors. Its hygroscopic nature necessitates proper storage to maintain purity and efficacy over time.
FAQs
1. What is the shelf life of sodium tetraborate decahydrate when stored properly?
When kept in a tightly sealed container away from moisture and direct sunlight, sodium tetraborate decahydrate retains its stability and purity for up to 2–3 years. Exposure to humid conditions may cause clumping but does not significantly alter its chemical properties if the container remains unopened.
2. Can this grade of sodium tetraborate be used for preparing borate buffers in molecular biology?
Yes, the 99.5% purity and analytical grade make it suitable for preparing borate buffers used in gel electrophoresis and other molecular biology applications. Its consistent dissociation in solution ensures reliable buffer performance for DNA/RNA separation and protein assays.
3. Is this product compatible with common laboratory solvents like ethanol or acetone?
Sodium tetraborate decahydrate is primarily soluble in water and glycerol, with limited solubility in ethanol (approximately 1 g/100 mL at 25°C). It is practically insoluble in acetone, so alternative solvents should be considered if non-aqueous solutions are required.
4. How does the decahydrate form differ from anhydrous sodium tetraborate in applications?
The decahydrate form contains 10 molecules of water per borate unit, making it more soluble in water and easier to dissolve for aqueous solutions. Anhydrous sodium tetraborate, lacking water, is less soluble and typically used in high-temperature applications like glass manufacturing or as a flux.
5. What precautions should be taken when handling this chemical in powder form?
While sodium tetraborate is relatively low in toxicity, it is recommended to wear gloves, safety goggles, and a lab coat to avoid skin or eye irritation. Work in a well-ventilated area or under a fume hood if generating dust, and avoid inhaling fine particles to prevent respiratory discomfort.
