High-temperature material processing and ash analysis require specialized vessels capable of withstanding extreme thermal stress. Professional laboratory crucibles and incinerating dishes are engineered from technical porcelain and quartz to provide exceptional heat resistance and chemical stability. As a core component of our vessels range within general laboratory consumables, these items are essential for gravimetric analysis and ignition processes.
Why Choose Professional Laboratory Crucibles?
Our curated collection of thermal processing vessels is designed for durability and precise analytical performance:
- Glazed Porcelain Crucibles: We stock LLG Porcelain Crucibles in tall form with capacities ranging from 15 mL to 72 mL, featuring glazed surfaces for easy cleaning and chemical resistance.
- Incinerating Dishes: Utilize LLG Incinerating Dishes (64 mL to 103 mL) designed for deep form applications without lids, ideal for high-temperature sample combustion.
- Standardized Dimensions: Explore crucibles manufactured to DIN standards (e.g., 3/35, 3/45, 3/50) to ensure compatibility with standard laboratory furnace equipment and tongs.
- Thermal Resilience: Find heat-resistant porcelain and quartz vessels designed to maintain structural integrity during rapid heating and cooling cycles.

Frequently Asked Questions
1. What is the benefit of a glazed porcelain crucible?
The glaze on LLG porcelain crucibles provides a smooth, non-porous surface that prevents sample absorption and makes the vessel easier to clean after high-temperature use.
2. Why use a tall form crucible design?
Tall form crucibles, such as the DIN 3/35 or 3/45 models, are designed to minimize sample loss during intense heating or chemical reactions while providing a stable base for furnace use.
3. Can these crucibles be used in a muffle furnace?
Yes, LLG porcelain crucibles and incinerating dishes are specifically designed for high-temperature applications in muffle furnaces and over Bunsen burners.
4. Do these crucibles come with lids?
Crucibles and lids are often sold separately to allow for customized setups; however, many incinerating dishes are intended for use without lids to allow for full sample oxidation.
