Volumetric Measuring Equipment
Beakers
A beaker is a cylindrical glass or plastic vessel used for holding liquids. It is a multi-purpose piece of equipment used for containing a chemical reaction, measuring liquids, heating them over a Bunsen burner's flame or collecting them in a titration experiment.

Burette
A burette is a cylindrical, laboratory glass apparatus that is used to measure the volume of liquids. It is very accurate and is used for precision experiments, such as titration. For a burette to perform optimally, and give precise results, it must be properly cleaned.

Distilling Flask
A distilling flask is a round bottomed container that has two openings and some sometimes a long neck. It is made entirely from glass and is used for chemical distillation processes. It is also a key equipment in almost all laboratories.

Dropper
A dropper pipette or chemical dropper is a device with a piston-driven air displacement mechanism used to transport a given volume of liquid mostly in the laboratory. Dropper pipettes have a locking system that allows them to be very accurate in transporting and dispensing of exact volumes of liquids.

Erlenmeyer Flask
An erlenmeyer flask is a cone-shaped container with neck, so you can hold the flask or attach a clamp or use a stopper. Erlenmeyer flasks are used to measure, mix, and store liquids. The shape makes this flask very stable. They are one of the most common and useful pieces of chemistry lab glassware. Most Erlenmeyer flasks are made of borosilicate glass so that they can be heated over a flame or autoclaved. The most common sizes of erlenmeyer flasks are 250 ml and 500 ml. They can be found in 50, 125, 250, 500, 1000 ml.

Florence Flask
A Florence flask is a laboratory glassware that is used to hold chemical solutions. It has a long neck with a round or flat bottom. Most of the Florence flasks are made of borosilicate glass, which is hard to break even when exposed to high amounts of heat.

Graduated Cylinder
A graduated cylinder is a relatively slim glass or plastic cylinder used specifically for calibrating beakers or measuring a liquid's volume. Graduated cylinders come in a variety of sizes such as 10 ml, 25 ml, 50 ml,100 ml, 500 ml and 1,000 ml. Scientists take measurements by viewing, at eye-level, the lowest point of the convex dip that the liquid in the cylinder makes.

Pipette
A pipette transfers relatively small amounts of liquid. In the most commonly used pipettes, experimenters draw liquid into one end of a glass or plastic cylinder by the prior squeezing of the rubber or plastic ball at the opposite end. The amount of liquid able to be drawn into the pipette is usually fixed, to enable accuracy in measurement.

Types of Pipette
Micro Pipette
Micro pipettes are the standard laboratory equipment used to measure and transfer small volumes of liquids.

Mohr Pipet
A Mohr Pipet is a graduated pipet that is designd to deliver small portions of a liquid or solution. These portions are determined by recording the difference between the initial and final volume readings.

Serological Pipette
The serological pipette is frequently used in the laboratory for transferring milliliter volumes of liquid, from less than 1 ml to up to 50 ml. The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable. Both kinds of pipettes use a pipet-aid, for the aspiration and dispensation of liquids. Different sizes of pipettes can be used with the same pipet-aid for a variety of experimental assays. For example, serological pipettes are useful for mixing chemical solutions or cell suspensions, transferring liquids between receptacles, or carefully layering reagents of different densities. With careful attention to the level of liquid being aspirated and dispensed, serological pipettes can be useful tools for transferring accurate milliliter volumes of solutions in the lab.

Volumetric Pipet
The volumetric pipet has a single graduation that allows it to deliver one specific volume accurately. There are many different sizes of volumetric pipets (1-, 5-, 10-, 25-, 50-, and 100-mL volumetric pipets are common). A volumetric pipet is accurate at the temperature at which it has been calibrated. The temperature where the volume is accurate is usually printed on the neck of the pipet. If you are working at a different temperature, the volumetric pipet should be calibrated.

Volumetric Flask
A volumetric flask is characterized by having a bulb and a long neck. Most volumetric flasks have a flattened bottom so that they can be set onto the lab bench, though some volumetric flasks have rounded bottoms.
A volumetric flask is used to measure very precisely one specific volume of liquid (100 ml, 250 ml, etc., depending on which flask you use). This flask is used to prepare a solution of known concentration. A volumetric flask should not be used to heat substances or store solutions, and you should avoid pipetting directly from the volumetric flask.
