Lab+Equipment

__This Page will explain the Lab Equipment and how to use it.__ ** Clay triangle: ** A small triangle made of steel rods that are coated in ceramic to withstand heat. A clay triangle can be placed on a ring stand to hold a beaker, and heat can then be applied to the beaker from below using a bunsen burner. A clay triangle can also be used to holda separatory funnel in an upright position. Clay triangles are not used that much anymore, as chemists usually heat beakers directly on an electric hotplate instead of with a bunsen burner. []  [] ** Beaker tongs: ** An over sized pair of tweezers used for picking up a hot beaker so that one does not burn ones hands.

It is most often used in titration to hold the liquid that is being titrated. [|http://www.chem.ubc.ca/courseware/121_glossary/glossary.html#] ** Graduated cylinder: ** A thick-walled glass tube used for measuring out volumes of liquid. The tube has an internal diameter of 1 to 3 cm, is closed at one end, and has a millilitre volume scale painted on the side. Graduated cylinders are typically manufactured with maximum volumes of 10, 25, 50, or 100 mL.

Used mostly for covering beakers when boiling water or to prevent dust from falling into the beaker. [|http://www.chem.ubc.ca/courseware/121_glossary/glossary.html#] Test tube: A clear, cylindrical glass tube open at one end and rounded at the other; used in laboratory experimentation.

 * Beaker: ** A glass container used for holding liquids; comes in many volume sizes and glass thicknesses.

Test tube block: A piece of wood with 6 to 20 large holes drilled in it to hold test tubes. [|http://www.chem.ubc.ca/courseware/121_glossary/glossary.html#] Test tube clamp: Similar to beaker tongs, but much smaller and designed to hold a test tube. [|http://www.chem.ubc.ca/courseware/121_glossary/glossary.html#] The Evaporating Dish is used to heat and evaporate liquids. []

The Funnel is a piece of equipment that is used in the lab but is not confined to the lab. The funnel can be used to target liquids into any container so they will not be lost or spilled. []

Bunsen burners are used for heating and exposing items to flame. They have many more uses than a hot plate, but do not replace a hot plate. [] Crucible tongs are large pincers made of welded steel that are used to grasp and take a hot crucible out of a fire or furnace, or to move a crucible from one location to another. [] Electronic balance- a balance that generates a current proportional to the displacement of the pan [] Labrotory Scoop - Scoops up powder and other substances [] A striker is used to light a flame, for instance the Bunsen burner flame. The striker does this by using flint to strike a rugged surface. []
