Product Description
Ammonium sulfate is a versatile inorganic salt widely used in laboratories, research institutions, and educational settings. The Emparta® A grade from Merck ensures high purity and consistency, making it ideal for applications like protein purification, precipitation reactions, and as a nitrogen source in microbiological media.
This 5 kg pack is perfect for bulk usage in academic labs, where reliability and batch-to-batch uniformity are critical. Whether you’re a student conducting experiments or a researcher needing precise results, this lab-grade ammonium sulfate delivers performance you can trust.
At eqipped, we source directly from Merck to guarantee authenticity. Our streamlined supply chain ensures you receive your order quickly, so you can focus on your work without delays.
Key Applications
Ammonium sulfate is commonly used in:
- Protein purification via salting out
- Precipitation of DNA/RNA
- Nitrogen source in microbial cultures
- Analytical chemistry standards
- Educational lab experiments
Why This Product Stands Out
The Emparta® A grade is Merck’s premium offering, designed for demanding applications. Unlike industrial-grade alternatives, this version undergoes rigorous quality checks to eliminate impurities that could interfere with sensitive assays. The crystalline form dissolves easily, ensuring homogeneous solutions for accurate results.
For researchers and educators, consistency is non-negotiable. This product’s lot-specific certification provides traceability, so you can replicate experiments with confidence.
Safety and Handling
Ammonium sulfate is generally safe but should be handled with standard lab precautions. Wear gloves and goggles when handling, and store in a cool, dry place away from moisture. Avoid inhalation of dust.
Risk Note: While not highly hazardous, prolonged exposure may cause skin or respiratory irritation. Follow lab safety protocols and refer to the SDS for detailed guidelines.
Buying Guide: How to Choose the Right Ammonium Sulfate
When selecting ammonium sulfate for your lab, consider:
- Grade: Lab grade (Emparta® A) is essential for research; avoid agricultural grades.
- Pack Size: 5 kg is ideal for frequent use; smaller packs suit occasional needs.
- Supplier Reputation: eqipped partners with Merck to ensure authenticity.
- Certification: Look for lot-specific COAs for traceability.
