Description

Platinum Crucibles Molds and Boats are indispensable in scientific and industrial applications due to their exceptional thermal stability, chemical inertness, and durability. Made from pure platinum or platinum alloyed with metals like gold, iridium, and rhodium, they withstand extreme temperatures above 1,700 °C without melting or reacting with the sample, ensuring purity and accuracy in analyses. Their resilience against corrosion and ability to be reused make them a cost-effective solution for high-temperature processes, including gravimetric analysis, fusion reactions, and materials science research. Available in various sizes and designs, including those with reinforced rims or lids to prevent contamination, Platinum Crucibles Molds and Boats are tailored for different specific needs, underscoring their critical role in ensuring the reliability and precision of experimental and manufacturing processes.

Applications of Platinum Crucibles

High-Temperature Strength: Platinum crucibles offer high-temperature strength up to 2192°F (1200°C), making them ideal for applications requiring extreme heat resistance.
Corrosion and Oxidation Resistance: These crucibles are known for their excellent resistance to corrosion and oxidation, ensuring durability in challenging environments.
Chemical Attacks Resistance: Platinum crucibles exhibit exceptional resistance to chemical attacks by acids and fusion mixtures, making them suitable for various chemical processes and applications.
Laboratory Applications: Widely used in laboratories for fusions, wet chemistry, digestion, ash testing, and Loss on Ignition (LOI) applications due to their reliability and inertness.
XRF Sample Preparation: Platinum crucibles are commonly utilized for X-ray fluorescence (XRF) sample preparation, ensuring accurate and reliable results in analytical chemistry.
Precision Manufacturing: These crucibles are manufactured to exact dimensions and weights, ensuring high quality and reliability in analytical processes like XRF, ICP, and AA analysis.
Asset Tracking: Each platinum crucible is engraved with a serial number for easy asset tracking, enhancing traceability and quality control in laboratory settings.
Non-Wetting Properties: The combination of platinum and gold in some crucibles imparts a negative adhesion coefficient, preventing droplets from adhering to the surface during sample preparation for ICP, AA, and XRF analysis.

Packaging

Our Platinum Crucibles, Molds and Boats are clearly labeled externally to ensure efficient identification and quality control. To prevent any damage during storage or transportation, we take great care.
