Description of Standard Platinum Dish
Our Platinum Crucibles and Molds are manufactured using a 5% Au-Pt alloy, combining the strength and durability of platinum with the added benefits of gold. This 5% Au-Pt alloy is particularly well-suited for sample preparation prior to XRF analysis, as its “non-wetting” property significantly enhances the ease of bead sample removal after fusion, ensuring clean and accurate results. These crucibles and molds are engineered to withstand the rigors of repeated high-temperature use, making them an ideal choice for laboratories and industrial settings where precision and reliability are paramount.

Applications of Standard Platinum Dish
- High-Temperature Chemical Analysis: Ideal for ashing, fusing, and melting samples in laboratory settings.
- Thermal Gravimetric Analysis (TGA): Used to measure changes in the weight of a sample as it is heated, cooled, or held at a constant temperature.
- Crucible for Fusion Processes: Employed in the preparation of glass, ceramics, and other materials requiring high-temperature fusion.
- Sample Preparation for XRF Analysis: Used for preparing homogeneous samples for X-ray fluorescence (XRF) analysis.
- Catalyst Testing: Utilized in experiments involving high-temperature reactions and catalyst performance evaluations.
Packaging of Standard Platinum Dish
Our standard platinum dishes are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
FAQs
Q1 What temperatures can a Standard Platinum Dish withstand?
Platinum dishes can typically withstand temperatures of up to 1700°C, making them ideal for high-temperature applications such as sample melting or ash testing.
Q2. Is a Standard Platinum Dish resistant to chemical corrosion?
Yes, platinum is highly resistant to most acids, alkalis, and other chemicals, ensuring the dish remains intact in corrosive environments.
Q3. How should I clean and maintain a Standard Platinum Dish?
To clean a platinum dish, use mild detergents and avoid abrasive materials that could scratch the surface. For tough residues, cleaning with diluted acid solutions is often recommended.
