Pipeclay Triangle for holding a crucible heating

Short Description:

It is twisted with iron wire and covered with porcelain tubes, of different sizes. It can be used to support a burning crucible or a small evaporation pan for heating. When the crucible is placed, the bottom of the crucible should be placed on one of the three porcelain tubes horizontally and diagonally.

Product information

The Pipeclay Triangle is a crucible for burning.

A triangular support made of wound heat - resistant ceramic tubes and iron wire, used to support a crucible for heating and preventing cracking.

The Pipeclay Triangle can withstand high temperatures because it is encased in heat-resistant ceramic tubes, and it can withstand weight because the hollow tubes are threaded with iron wire. When an object needs intense heat from a Bunsen burner, a mud triangle is usually placed on an iron ring as support for the object. Or in experiments that require an alcohol lamp to heat a crucible.

Product Details

High Temperature Resistance

It has the characteristics of high melting and boiling point and can be used at high temperature without being affected.

Electrical Insulating

Insulator has high resistivity at room temperature. It can be used in equipment requiring insulation.

Function

Laboratory commonly used tripod support heating, and the laboratory common crucible is made of porcelain, tripod is made of iron. The expansion coefficient of porcelain and iron is different. If the porcelain crucible is heated directly on a tripod, it is easy to cause the porcelain crucible to burst.

The shape of the Pipeclay Triangle is simpler than the crucible, and the thickness is larger, so it is not easy to break. Therefore, the porcelain crucible should be placed on the Pipeclay Triangle, the Pipeclay Triangle on a tripod, and then reheated.

Note

(1) often used with a tripod.

(2) can not be slammed, so as not to damage the porcelain tube.

(3) After using the mud triangle, please do not directly touch the heating part to prevent scald, and wait for the mud triangle to cool down before taking it off.
