Explain the Following Chemistry Lab Equipments Flashcards

A piece of glassware in which the opening diameter is approximately the same as the base diamater. Used to hold liquids and sometimes solids. Graduations on the sides are approximate.

A piece of glassware with the opening diameter significantly smaller than the base diameter. The diameter gradually narrows from the base up to near the top. It is used for holding liwuids. It is resistant to splashing when mixing liquids. Graduations on the sides are approximate.

A piece of glassware with the opening diameter significantly smaller than the base diameter. The bottom of the flask is generally rounded, with a long, narrow neck. It is used for holding and mixing liquids. The bottom is sometimes flat, and sometimes rounded. Often used in organix chemistry experiments. Not usually graduated.

A piece of glassware with the opening diameter significantly smaller than the base diameter. The bottom is usually rounded, and there is a line drawn on the neck approximately halfway up. It measures an exact amount of liquid to two decimal places. It is used for mixing specific concentrations of solutions.

A mechanical balance used to determine mass of an object, by moving sliders on three bars until the mass on the pan is balanced by the positions of the sliders.

A balance used to determine the mass of an object. If it is at zero when turned on, the mass can be determined simply by placing the object on the pan and reading it.

A balance used to determine the mass of an object to a high degree of precision. Readings made by this balance must be reported to 4 decimal places. Because of its high degree of precision, the pan is enclosed in a chamber to eliminate the effect of air currents in the room on the reading.

A piece of glassware that is used to determine the volume of a liquid. It is the only piece of glassware which can be used to accurately determine the volume of a liquid.

A glass tube, similar to a graduated cylinder in that it is graduated and designed to measure the volume of liquids. However, a burette requires something to hold it upright, such as a burette clamp, and also has a spigot on the bottom of it.

A piece of equipment used to determine the length of an object.

Used for collecting the filtrate during a filtration.

A tube which attaches to the faucet of the sing, and creates a vacuum in the attachment when water is running through it.

A black rubber disk used to create a seal between the filtering flask and the funnel.

A funnel with a flat bottom where filter paper is placed, and holes to allow the filtrate to pass through.

A heavy metal base with a pole sticking up, used to attach objects to during experiments. The weight attached to the pole MUST be over the base to avoid instability.
