Crucible with lid

A standard crucible to be used in high temperature experiments. Constructed of glazed porcelain for strength, thermal performance, enhanced chemical resistance and which are non-reactive and can withstand heat from a Bunsen burner

A low form porcelain crucible is used in laboratories for high-temperature chemical applications, particularly those that require a large surface area for heating, evaporation, or drying. Its broad, shallow shape is designed to increase the rate of heating and promote uniform reactions.

 Key applications and features

• Gravimetric analysis: The low form is ideal for gravimetric analysis, a technique that requires precise measurement of mass changes after a sample has been heated to a constant weight. The shape facilitates complete combustion and ashing of organic materials.
• Rapid heating and evaporation: The wide, shallow design exposes a larger surface area to heat, which is particularly useful for processes that require controlled evaporation or drying of powders, precipitates, and liquids.
• Material calcination and fusion: Low form crucibles are used to heat substances to high temperatures to bring about thermal decomposition or other chemical changes, such as in calcination or fusion processes.
• High-temperature chemical reactions: Made from high-quality, heat-resistant porcelain, these crucibles can withstand temperatures of up to 1050°C (1900°F), making them suitable for intense heat applications.
• Minimized contamination: Porcelain is chemically inert and non-reactive with most substances, which is crucial for chemical analyses where high purity must be maintained.
• Glazed surface: The interior of the crucible is typically glazed to prevent materials from sticking, which makes cleanup easier and ensures all residue can be removed for accurate results. 

• Low form: The broad, shallow shape offers a high surface area-to-volume ratio, making it ideal for fast heating, drying, and evaporating.
• Tall form: The narrow, tall shape is more effective at limiting splattering and material loss from bubbling. This design helps contain reactions and control the atmosphere inside the crucible, which is particularly useful when working with volatile substances.
