The Wide Form Porcelain Crucibles from United Scientific are engineered for demanding thermal applications, including gravimetric analysis, ashing, and chemical ignitions. Manufactured from high-quality laboratory porcelain, these crucibles are designed to withstand extreme temperatures up to 1150°C. Each crucible features a wide-mouth design to maximize surface area for evaporation and is supplied with a matching porcelain lid to prevent sample loss and contamination during the heating process. The inner and outer surfaces are professionally glazed—excluding the bottom and rim—to ensure easy sample recovery and resistance to chemical attack.

Overview

Lead Times May Vary

Standardized sizes to accommodate micro-analytical work through bulk sample ashing.

Features:

Exceptional Thermal Range: Safe for use in muffle furnaces and over Bunsen burners, maintaining structural integrity up to 1150°C.
Chemical Durability: Highly resistant to most laboratory reagents; the glazed surface prevents sample absorption and facilitates thorough cleaning.
Optimized Wide Form: The lower height and wider diameter compared to "tall form" crucibles provide greater stability and a larger surface area for oxygen-rich ashing.
Total Containment: Each unit includes a fitted lid, essential for preventing "spitting" or the loss of volatile components during intense heating.

Critical Usage Guidelines:

CAUTION! Thermal Stress Prevention: To avoid cracking or shattering, do not exceed a heating or cooling rate of 200°C per hour. Always allow crucibles to cool in a desiccator or on a ceramic heat-resistant mat.
Chemical Limitations: Do not use with Hydrofluoric acid (HF), as it will dissolve the porcelain and glaze.
Handling: Always use stainless steel crucible tongs to handle hot porcelain to prevent thermal transfer and ensure operator safety.
