Product Overview
This Puratronic™-grade cadmium shot delivers ultra-high purity at 99.9997% (metals basis), ensuring minimal trace impurities for critical laboratory applications. The 1-3mm shot form provides consistent particle size distribution, optimizing handling and dosage accuracy in sensitive procedures. Engineered for demanding environments, this cadmium maintains exceptional chemical stability and low reactivity, reducing contamination risks during storage or use. The Puratronic™ certification guarantees rigorous quality control, with each batch tested for metallic and non-metallic impurities to meet ASTM and SEM specifications. Its uniform spherical shape minimizes surface area exposure, preserving purity during long-term storage under inert conditions. Compatible with most standard lab equipment, this cadmium shot integrates seamlessly into existing workflows without requiring specialized handling protocols beyond standard heavy metal precautions. The material’s high density (8.65 g/cm³) and low melting point (321°C) make it particularly suitable for applications requiring precise thermal control or alloy preparation. Each pack size (50g, 250g, 1kg) is vacuum-sealed in high-barrier packaging to prevent oxidation and moisture absorption during transit and storage.
FAQs
1. What is the typical shelf life of this Puratronic™ cadmium shot when stored properly?
When stored in its original vacuum-sealed packaging at room temperature (15-25°C) away from direct sunlight and moisture, this cadmium shot maintains its specified purity for at least 24 months from the date of manufacture. Extended storage beyond this period may require re-certification of purity levels before use in critical applications.
2. How does the 1-3mm shot size compare to cadmium powder for laboratory applications?
The shot form offers several advantages over powder: reduced dust generation during handling, lower surface area exposure to atmospheric contaminants, and easier portion control for weighing procedures. However, applications requiring rapid dissolution or fine dispersion may still prefer powdered forms, though with increased risk of oxidation and inhalation hazards.
3. What compatibility issues should be considered when using this cadmium with other lab materials?
Cadmium reacts with strong acids (particularly nitric and sulfuric), halogens, and some organic compounds. Avoid contact with aluminum, zinc, or copper containers as galvanic reactions may occur. Use only with PTFE, glass, or high-density polyethylene labware for storage and handling to prevent contamination or container degradation.
4. Are there lower purity alternatives available for less critical applications?
For applications where 99.9997% purity isn’t essential, 99.99% or 99.9% purity cadmium shot is typically available at lower cost. These grades may contain higher levels of lead, zinc, or iron impurities but remain suitable for many industrial and educational applications where trace contaminants don’t significantly affect results.
5. What are the recommended storage conditions to maintain the shot’s purity?
Store in the original vacuum-sealed packaging until use. After opening, transfer to a secondary container with argon gas purging and keep in a desiccator cabinet maintained below 30% relative humidity. Avoid temperature fluctuations and store separately from reactive chemicals, particularly oxidizing agents or compounds containing sulfur.
