What is the use of triangular file in laboratory?

What is the function of triangular file in laboratory? A triangular file is a specialized tool for trimming and sharpening edges.

What is the use of crucible?

Used from ancient times as a container for melting or testing metals, crucibles were probably so named from the Latin word crux, “cross” or “trial.” Modern crucibles may be small laboratory utensils for conducting high-temperature chemical reactions and analyses or large industrial vessels for melting and calcining …

What is a Pipestem triangle made of?

Pipe stem triangles are made of iron and covered with pipe clay.

What is the use of crucible and cover in laboratory?

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.

What is the use of water bath in laboratory?

A water bath is a laboratory equipment that is used to incubate samples at a constant temperature over a long period of time. Water bath is a preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition.

What are the safety precautions inside the laboratory?

Dress for work in the laboratory. Wear clothing and shoes that cover exposed skin and protect you from potential splashes. Tie back long hair, jewelry, or anything that may catch in equipment. Never eat food, drink beverages, chew gum, apply cosmetics (including lip balm), or handle contact lenses in the laboratory.

How do crucibles work?

A crucible is a pot that is used to keep metals for melting in a furnace. Furnace crucibles are designed to withstand the highest temperatures encountered in the metal casting works. The crucible should essentially be made of materials with a much higher melting point than that of the materials to be melted.

What exactly is a crucible?

crucible \KROO-suh-bul\ noun. 1 : a vessel in which metals or other substances are heated to a very high temperature or melted.

Why is a Pipestem triangle used?

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 purpose of a watch glass?

A watch glass is a round, concave glass dish used for evaporation in chemistry. It can also be employed for weighing solids and as a lid for flasks and beakers.

What is the use of dropper in laboratory?

An eye dropper, also known as a Pasteur pipette, or dropper, is a device used to transfer small quantities of liquids. They are used in the laboratory and also to dispense small amounts of liquid medicines.

What is the function of test tube?

Test tubes are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents.

What is the function of a clay triangle?

A clay triangle is a piece of laboratory equipment used in the process of heating substances. It is used in conjunction with other lab equipment to create a stable framework in which to place a substance — usually a solid chemical — while it is heated to a high temperature.

What is the purpose of a porcelain triangle?

A porcelain triangle is laboratory equipment used in the process of heating substances. It is used in conjunction with other laboratory equipment to create a stable frame in which to place a substance, usually a solid chemical, while heating to a high temperature.

What kind of wire makes a clay triangle?

Description. A clay triangle consists of three lengths of galvanized wire arranged in a triangle shape. The ends of the wires are twisted together, forming three straight wire stems projecting outward from each corner of the triangle. Each side of the wire triangle is covered with a ceramic sleeve, which is capable of withstanding very high…

What can a pipeclay triangle be used for?

A pipeclay triangle is constructed from wires with ceramic or catlinite tubing, allowing it to support heatproof crucible containers while providing direct heat. The alternative is wire gauze, which is better suited for work with beakers and other glassware containers that needs indirect exposure because they can be damaged by direct heat.
