What is Gooch Crucible?

Gooch crucible is a type of filtration device we can use in laboratories. This musical instrument was named after Frank Austin Gooch. We tin name information technology a Gooch filter as well. Gooch crucible is useful for collecting a precipitate directly within the vessel in which we can let the precipitate dry, make its ash and measure the weight of the analyte sample through gravimetric assay.

Originally, this device was made as a standard platinum crucible in laboratories, and it contained a perforated base of operations. This perforated base of operations is important in placing the asbestos lurid from the filter mat. Thereafter, the crucible was heated in an oven in lodge to let the pulp dry out until it obtained a constant weight that we can measure. This crucible can be field of study to a high temperature for drying the filtrate, and we can also oxidize the content in the crucible or brand the filtrate become its ash which has minimum weight. Even so, the use of platinum is expensive; thus, the cloth of the Gooch crucible was replaced with porcelain in 1882.

In some crucibles, in that location are asbestos double layers that separate them from a perforated porcelain plate. Additionally, some Gooch crucibles contain inorganic fibres such as glass in the identify of asbestos. Gooch crucibles made of borosilicate glass and fritted glass bases are also common nowadays. Platinum Gooch crucibles as well help in important applications like treatment corrosive materials. In such applications, we cannot use porcelain. Nonetheless, a Gooch crucible made of porcelain is enough for ashing a fabric at high temperature, and the crucibles made of borosilicate are enough for drying a textile.

What is Sintered Glass Crucible

Sintered glass crucible is a type of filtration device made of Pyrex glass. Pyrex glass is an excellent resistant glass type. It is fitted with sintered ground glass, filter disc at a small altitude above the lower end. Generally, this device is useful in directly collecting a precipitate that requires drying.

Moreover, these glass crucibles contain diverse degrees of porosity in order to suit precipitates of dissimilar sizes. There are two major types every bit G3 and G4; G3 is useful for nearly precipitates, whereas G4 is of import in filtering few precipitate types. These crucible types cannot withstand temperatures above 400 Celsius degrees.

Furthermore, nosotros cannot apply a sintered glass crucible directly on a flame. Therefore, the precipitate in the sintered glass crucible is dried at temperatures ranging from 110 to 120 Celsius degrees inside an electric oven.

What is the Departure Between Gooch Crucible and Sintered Drinking glass Crucible?

Gooch crucible and sintered glass crucible are filtration devices that we can utilize in laboratories for analytical processes. Gooch crucible is made of porcelain, whereas sintered glass crucible is made of Pyrex glass. The key deviation between Gooch crucible and sintered glass crucible is that Gooch crucibles can withstand very loftier temperatures while sintered glass crucibles cannot withstand temperatures above 400 Celsius degrees.

The below infographic shows the differences between Gooch crucible and sintered drinking glass crucible in tabular form.

Summary – Gooch Crucible vs Sintered Glass Crucible

Gooch crucible is a type of filtration device that we tin can use in laboratories. Sintered glass crucible is a blazon of filtration device made of Pyrex glass. The key deviation between Gooch crucible and sintered glass crucible is that the Gooch crucibles can withstand very high temperatures while sintered drinking glass crucibles cannot withstand temperatures higher up 400 Celsius degrees.
