Low-Wall (Low-Form) Crucibles with Lid, Glazed

This standard crucible is used in high-temperature experiments. It's made from glazed porcelain for strength, thermal performance and chemical resistance, is 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 needing a large surface area for heating, evaporation or drying. Its broad, shallow shape increases the rate of heating and promotes uniform reactions.

The low form is well suited to gravimetric analysis, a technique that requires precise measurement of mass changes after a sample has been heated to a constant weight, since the shape helps complete combustion and ashing of organic materials. The wide, shallow design also exposes a larger surface area to heat, useful for controlled evaporation or drying of powders, precipitates and liquids, and for calcination or fusion processes where substances are heated to bring about thermal decomposition or other chemical changes.

Made from high-quality, heat-resistant porcelain, these crucibles can withstand temperatures of up to 1050°C (1900°F). Porcelain is chemically inert and non-reactive with most substances, which matters for chemical analyses where high purity must be maintained, and the interior is typically glazed to stop materials sticking, making cleanup easier and helping ensure all residue can be removed for accurate results.

The main difference between a low form and a tall form crucible is shape, which dictates their best use. The low form's broad, shallow shape gives a high surface area-to-volume ratio, making it ideal for fast heating, drying and evaporating. The tall form's narrow, tall shape is more effective at limiting splattering and material loss from bubbling, helping contain reactions and control the atmosphere inside the crucible, particularly useful when working with volatile substances.
