Ceramic fiber squares are asbestos-free insulating squares that are ideal for protecting laboratory bench tops against heat. The squares can be cut to fit any lab application and are available in two thicknesses.
What are ceramic square used for?
Ceramic squares are commonly used to check machine alignments, level and machine square. Leveling mills and squaring up a machine is critical to both keeping your parts in tolerance and keeping a good finish on your part. Ceramic squares are much easier to handle then granite machine squares inside of a machine.
What is clay triangle in chemistry?
A clay triangle is a wire and ceramic triangle used to support a crucible while it is heated over a Bunsen burner. A crucible is a ceramic vessel with a lid that is used to heat solid chemical substances to high temperatures to dry them completely or to induce a reaction without solution.
What are the uses of laboratory equipment?
lab equipment and uses NAME USE beaker Used to hold and heat liquids. Multipurpose and essential in the lab. brushes Used to easily clean the inside of a test tubes and other glassware. Buchner funnel Used with vacuum flask for performing vacuum filtration. Bunsen burner Used for heating and exposing items to flame.
What is the purpose of a Scoopula?
Scoopula is a brand name of a spatula-like scoop utensil used primarily in chemistry lab settings to transfer solids: to a weigh paper for weighing, to a cover slip to measure melting point, or a graduated cylinder, or to a watch glass from a flask or beaker through scraping.
What is the function of a clay triangle?
Clay triangle A triangular device made of heat-resistent clay. Used to hold crucibles and porcelain dishes heated by a Bunsen burner. Distributes heat evenly over the surface of objects it holds.
What is a triangular file used for in chemistry?
Uses: To transfer solid chemicals in weighing. Triangular File: Description: Metal file with three cutting edges. Uses: To scratch glass or file.
Why use clay triangle over wire mesh?
Unlike wire gauze, which primarily supports glassware such as beakers, flasks, or evaporating dishes and provides indirect heat transfer to the glassware, the pipeclay triangle normally supports a crucible and allows the flame to heat the crucible directly.
What is a crucible used for in chemistry?
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 are the 20 laboratory apparatus and their uses?
More than 20 common laboratory apparatus their uses A microscope. Biologists, medical workers, and students love to use microscopes in their projects. Balance. What laboratory apparatus is used to measure mass? Volumetric flasks. Test tube. A bunsen burner. A voltmeter. Beakers. A magnifying glass.
Why is lab equipment important?
Science lab equipment allows students to actually perform experiments rather than just read about them. Instead of taking monotonous notes, they can observe and complete exciting experiments. Such hands-on learning often makes it easier to understand challenging theories and concepts.
What are laboratory equipments?
Science laboratory equipment refers to the various tools and equipment that are used by professionals or students working in a laboratory. The different laboratory equipment used are Bunsen burner, microscopes, calorimeters, reagent bottles, beakers and many more.
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 beaker used for?
Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat.
What does a watch glass do?
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 Pipestem 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 Florence flask?
The Florence flask is characterized by a long neck and rounded bottom with a flat base. It is useful as a reaction vessel as well as for heating solutions.
What is a Pipestem triangle made of?
Pipe stem triangles are made of iron and covered with pipe clay.
What is a file used for in chemistry?
items. File Used to grind down materials or sharpen items. with water or keep materials moist.
What is used to transfer liquids into small containers?
Pasteur pipettes (or pipets) are the most commonly used tool for transferring small volumes of liquids (< 5mL) from one container to another. To use a pipette, attach a dropper bulb and place the pipette tip into a liquid.
What is used to grind chemicals into powder?
Mortar and pestle – A mortar and pestle are used to crush and grind solids into a powder. Stirring rod – A skinny solid glass rod used in chemistry to mix chemicals and liquids.
Why do you need to heat the crucible plus cover on the clay triangle and heat with a burner flame for 5 minutes?
Heat a clean and dry porcelain crucible with lid (on a clay triangle supported on a ring stand) directly over a Bunsen burner flame for about 5 minutes. This will ensure that the crucible is clean and dry.
What is the purpose of wire gauze?
Wire gauze is an important piece of supporting equipment in a laboratory as glassware cannot be heated directly with the flame of a Bunsen burner, and requires the use of a wire gauze to diffuse the heat, helping to protect the glassware. Glassware has to be flat-bottomed to stay on the wire gauze.
Why use a crucible instead of a test tube?
The benefits of crucible lie in its ability to withstand very high temperatures, which makes it ideal for laboratory experiments involving extremely hot chemical reactions as well as corrosive and pigmentation processes. It is a common chemistry lab apparatus that is used for heat-related experiments.
What is a crucible when is a crucible used?
In chemistry, a crucible is a kind of laboratory equipment that is usually a small cup, about the size of a shot glass, made of porcelain or non-reactive metal. Crucibles are used to heat chemical compounds to very high temperatures using a gas burner.
