Product Overview
Paraformaldehyde LR Grade is a high-purity, polymerized formaldehyde derivative widely used in laboratory applications requiring stable and controlled formaldehyde release. This reagent-grade compound ensures minimal impurities, making it suitable for critical processes like tissue fixation, chemical synthesis, and long-term sample preservation. Its solid form (powder or flakes) allows for easy handling and precise dosing, while its LR grade guarantees reliability in analytical and preparative workflows. Paraformaldehyde decomposes slowly in aqueous solutions, releasing formaldehyde, which enhances its utility in crosslinking proteins and nucleic acids. The product is packaged to maintain stability and prevent moisture absorption, ensuring consistent performance across experiments. Whether used in histology, biochemistry, or materials science, this LR-grade Paraformaldehyde delivers reproducible results with minimal batch-to-batch variation. Store in a cool, dry place away from incompatible substances to preserve its integrity.
FAQs
1. What is the shelf life of Paraformaldehyde LR Grade?
When stored in a sealed container under recommended conditions, Paraformaldehyde LR Grade typically retains its stability for 2–3 years. Avoid exposure to humidity to prevent premature degradation.
2. Is this product compatible with aqueous solutions for fixation?
Yes, Paraformaldehyde LR Grade dissolves in water to release formaldehyde, making it ideal for preparing fixation buffers. Heat gently and adjust pH if needed for complete dissolution.
3. Are there safer alternatives to Paraformaldehyde for lab use?
Alternatives like glutaraldehyde or ethanol-based fixatives exist, but they may not offer the same crosslinking efficiency. Paraformaldehyde remains a standard due to its balance of effectiveness and cost.
4. How should I dispose of unused Paraformaldehyde?
Follow local hazardous waste guidelines. Neutralize with a suitable agent (e.g., sodium bisulfite) before disposal to minimize environmental impact and comply with lab safety protocols.
5. Can this grade be used for electron microscopy sample preparation?
Yes, Paraformaldehyde LR Grade is commonly employed in electron microscopy for its ability to preserve ultrastructure. Combine with glutaraldehyde for enhanced fixation in EM protocols.
