What is the use of a pipe clay triangle?
What is the use of a pipe clay triangle?
A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes.
What is a Pipestem triangle made of?
Pipe stem triangles are made of iron and covered with pipe clay.
Can a clay triangle be heated?
A clay triangle consists of three lengths of galvanized wire arranged in a triangle shape. Each side of the wire triangle is covered with a ceramic sleeve, which is capable of withstanding very high temperatures over direct flame from a Bunsen burner.
What is the function of Bunsen burner?
Bunsen burner, device for combining a flammable gas with controlled amounts of air before ignition; it produces a hotter flame than would be possible using the ambient air and gas alone.
What is the purpose of a ring stand?
In chemistry, a retort stand, also called a clamp stand, a ring stand, or a support stand, is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks.
What is a crucible and cover used for?
Crucible is used in the laboratory to contain chemical compounds when heated to extremely high temperatures. Crucibles are available in several sizes and typically come with a correspondingly-sized lid.
How do you use a pipe stem triangle?
The Pipestem triangle is used to support a crucible while it is being heated over a Bunsen burner. It is very heat resistant and can be used at high temperatures. Wire gauzes are used to support larger objects, such as beakers and evaporating dishes while they are being heated.
What is the function of rubber tubing in Bunsen burner?
Rubber tubing connects the Bunsen burner to the gas outlet nozzle on the work bench. Natural Gas connections may be made with rubber connections rated for hazardous/flammable gas. Inspect rubber tubing for defects or degradation that could lead to leakage of natural gas or improper seal around the gas outlet nozzle.
What is the purpose of the air holes needle valve and barrel?
The quantity of gas admitted to the burner is controlled by the needle valve, while the air needed for combustion is admitted at the small opening around the bottom of the barrel call air intake openings. The air is controlled by turning the collar so as to make the air holes larger or smaller.
What does a evaporating basin do?
Evaporating dishes are shallow open containers used for the evaporation of solutions and supernatant liquids to produce a concentrated solution or a solid precipitate of the dissolved substance.
What is the main purpose of crucible tongs?
Crucible tongs are scissor-like tools, but instead of having two blades, these tools are replaced with two pincers or pieces of metals that concave together, which allow the users to grasp a hot crucibles, flasks, evaporating dishes, or even small beakers.
How does a crucible work?
Crucibles have been used for thousands of years to make alloys and cast metals. To melt metal inside of a crucible, the materials are placed inside and heated until they reach their melting point. You can make a new alloy by melting a combination of materials with other elements inside of the crucible.
