Crucible with Lid – Porcelain

The porcelain crucible with lid is a high-temperature laboratory vessel designed for heating, calcining, and incinerating samples. Made from high-quality glazed porcelain, it offers excellent thermal shock resistance, chemical durability, and mechanical strength, making it suitable for repeated heating cycles in furnaces, hot plates, or over direct flame. The tight-fitting porcelain lid helps minimize contamination and prevents sample loss during experiments.

Key Features

Material: Premium glazed porcelain, resistant to most acids and alkalis
Temperature Resistance: Withstands continuous heating at high temperatures (up to ~1050–1200 °C, depending on grade)
Design: Round form with a snug-fitting lid to contain and protect samples
Surface Finish: Smooth glazed interior and exterior for chemical resistance and easy cleaning
Sizes Available: Offered in multiple capacities for varied laboratory needs

Applications & Uses

Gravimetric Analysis: Weighing samples before and after ignition to determine composition
Ashing & Incineration: Burning organic matter to obtain inorganic residue or ash content
Sample Preparation: Pre-treatment of solid and powdered samples before analysis
Material Testing: Heat treatment of small metal, ceramic, or mineral samples
Chemical Reactions: Conducting high-temperature reactions under controlled conditions
Educational Labs: Commonly used in teaching labs for demonstrating calcination, melting, and thermal decomposition

The porcelain crucible with lid is an indispensable tool in both research and teaching laboratories, offering reliability and durability for high-temperature analytical and preparative work.
