Laboratory Crucibles｜What Are They? Why They Are Important for Accurate Results?

What is a laboratory crucible?

  A laboratory crucible is a heat-resistant container used in chemical laboratories for high-temperature heating and melting of substances.

  The most common type is made of ceramic material or graphite, with clay as the binding agent that helps the crucible withstand temperatures up to over 1600 °C. Crucibles are usually placed in furnaces to melt the substance and then poured into molds with either electric or induction furnaces.

  A laboratory crucible is a specialized container used in a range of scientific processes, from melting and smelting metal to evaporating liquids.

  Lab crucibles are typically made from materials such as ceramic, quartz or metal and come in a variety of shapes and sizes, including conical, bowl-shaped or flat-bottomed designs.

  Crucibles are usually used for high temperature experiments that require extreme heat and thermal shock resistance. A laboratory crucible is a cup-shaped container made of heat-resistant material such as porcelain or inert metal, usually platinum.

  This container is used for a variety of laboratory tasks, including heating samples to high temperatures and performing gravimetric analyses. Laboratory crucibles are most commonly small (10–15 mL) and have a loose-fitting lid to allow gases to escape during heating.

  Crucibles also come in various sizes and shapes, such as low form or high form, and can be sold in quantity at an affordable price at a professional crucible supplier’s end or individually at hobby shops with a large mark-up.

Find out why laboratory crucibles are essential pieces of equipment for obtaining precise data.

  A laboratory crucible is an essential piece of equipment for scientists conducting accurate and precise experiments. Designed to withstand high temperatures, crucibles are commonly used for weighing, mixing, heating, and melting materials in laboratories.

  Laboratory crucibles are used to conduct a range of chemical reactions. When heated, they efficiently transfer heat and provide consistent temperatures that are necessary for creating accurate results. 

  Crucibles also help protect samples from oxidation and other contaminants, thereby ensuring accurate data. Additionally, they offer protection from chemicals, as well as enhanced safety for the operator, by preventing splashing or spilling of dangerous materials. 

  Finally, crucibles are highly durable and easy to clean for repeated use over the course of an experiment.
