From sample prep to small-batch metal melting or thermal analysis, this mid‑size crucible is the ideal workhorse for labs and workshops. Rated to a blazing 1750 °C, the 500 mL LARK® Alumina Crucible offers reliable performance with excellent handling and recovery after heating.
🌟 Why Opt for the 500 mL Version?
- Optimized volume for routine tasks
At 500 mL, it balances convenience and capacity—perfect for moderate‑scale experiments, QA samples, alloy tests, or ash analyses mxrady.com+12kerroscale.com+12Amazon India+12Amazon IndiaAmazon India+2mxrady.com+2mxrady.com+2. - High-purity alumina (99.95 %)
Made of premium Al₂O₃, it resists corrosion, chemical attack, and extreme temperatures up to 1750 °C—even under reducing or oxidizing conditions mxrady.com+2Tradeindia+2Imimg+2. - Superior thermal cycle tolerance
With a recommended initial heat‑ramp of 150 °C/hour (often extended to 300 °C/hr) for the first 1–1.5 hours, it resists cracking and extends lifespan Amazon India+5graphitestore.com+5Flipkart+5graphitestore.com+4mxrady.com+4Flipkart+4.
🔧 Ideal Applications
- Ash content measurements in food, biomass, or environmental samples
- Metal melting tests before scaling up to 1 L batches
- Ceramic and material science experiments requiring controlled volumes
- Educational & industrial labs seeking dependable mid-size crucibles
✔️ Benefits That Boost Your Listing
- Middle-ground capacity appeals to a wider range of lab needs than a tiny or full-size crucible
- High temperature rating and chemical inertness provide strong selling points in technical specs
- Batch-friendly—great for labs running multiple samples without swinging to larger volumes
- Easy upsell opportunities: bundle with TGA sample pans, furnace gloves, tongs, or smaller 250 mL versions
🛡️ Care & Best Practices
- Initial slow ramp: Heat at 150–300 °C/hour for ~1–1.5 hrs to prevent early thermal shock Amazon India+10mxrady.com+10mxrady.com+10Imimg.
- Controlled cooldown: Cool at half-rate of heating—about 75–150 °C/hour graphitestore.com.
- Dry before use: Any moisture can cause cracking under high heat—fully dry if wet.
- Handle gently: Avoid collisions; inspect for micro-cracks before use.
- Use heat-safe tools: Employ ceramic tongs or high-temp supports for safe handling.
💡 Compare the 500 mL Advantage
| Crucible Size | Volume | Best For |
|---|---|---|
| 250 mL | Small | Tiny samples, precious metals in jewelry |
| 500 mL | Medium | Routine lab tests & moderate-scale melting |
| 1000 mL | Large | Bulk melting, large ash testing, industrial use |
The 500 mL hits the sweet spot—ideal for users who need more than a small crucible but don’t require the bulk of a 1 L version.
📈 Sales Strategy & Cross-Sells
- Highlight mid-range appeal: “Not too small, not too big—just right for everyday lab work”
- Bundle with: furnace gloves, crucible tongs, thermo‑couples, or smaller/larger Al₂O₃ crucibles
- SEO keywords: “500 mL alumina crucible,” “mid-size high-temp crucible,” “LARK 1750 °C crucible”
