Product Overview
This Puratronic™ grade magnesium turnings deliver exceptional 99.98% purity on a metals basis, making them the premium choice for demanding laboratory applications where trace impurities can compromise results. The uniform 1cm (0.4in) maximum particle size ensures consistent reactivity while minimizing dust formation during handling. Produced through advanced purification processes, these turnings maintain ultra-low levels of iron, copper, and other metallic contaminants that could interfere with sensitive reactions. The material’s high surface area-to-volume ratio facilitates rapid dissolution in acidic media while maintaining structural integrity during storage. Each batch undergoes rigorous ICP-OES analysis to verify composition, with certificates of analysis provided for traceability. The turnings come in hermetically sealed packaging with argon backfilling to prevent oxidative degradation, preserving the metal’s reactive properties until use. Their consistent particle distribution eliminates the need for additional grinding or sieving in most applications, saving valuable preparation time. The material’s purity level meets or exceeds requirements for semiconductor-grade processes and advanced materials research.
FAQs
1. What is the typical moisture content of these magnesium turnings?
The Puratronic™ grade magnesium turnings are packaged under argon with moisture content maintained below 50ppm, as verified by Karl Fischer titration in our quality control process.
2. Can these turnings be used directly in organometallic synthesis without further purification?
Yes, the 99.98% purity level and controlled particle size distribution make these turnings suitable for direct use in most organometallic reactions, including Grignard reagent preparation, without requiring additional purification steps.
3. How does the particle size distribution affect reaction kinetics compared to magnesium powder?
The 1cm maximum size provides a balance between surface area and handling safety, offering faster reaction initiation than larger chunks while being less pyrophoric than fine powders, resulting in more controllable reaction rates.
4. What is the recommended storage protocol to maintain the purity over extended periods?
Store unopened containers in a cool, dry environment below 25°C with relative humidity under 40%. Once opened, transfer unused portions to an airtight container with argon purging and consume within 6 months for optimal performance.
5. Are there any known compatibility issues with common laboratory solvents?
These turnings show excellent compatibility with ethers, hydrocarbons, and chlorinated solvents typically used in organometallic chemistry, though standard precautions for reactive metals should be followed when handling.
