What is gooch crucibles?

Gooch crucibles are specialized porcelain crucibles designed for the filtration of precipitates in analytical chemistry. They are named after their inventor, F. Gooch. The crucibles have a perforated bottom, which allows the filtrate to pass through while retaining the solid precipitate. They are typically made of porcelain or high-temperature ceramics such as alumina or zirconia.

Gooch crucibles are used in analytical chemistry for the separation and purification of substances. They are commonly used for the filtration of heavy metals, organic matter, and other impurities from solutions. The crucibles are also used for ashing, where the sample is burned in the crucible to remove organic matter and leave behind the inorganic residue.

Gooch crucibles come in different sizes, and their suitability for different applications depends on their size and material of construction. They are often used in combination with vacuum filtration systems to increase filtration efficiency. Proper care must be taken when handling and using Gooch crucibles, as they are fragile and can easily break or crack.
