Measuring Instruments Volume II

Instruments for measuring volume II are widespread in all spheres of everyday life, in the market when ordering a liter of oil, in the sale of cosmetics when buying a shampoo. Similarly in the area of research sciences, medical, bioanalysis, chemistry, etc. Where by means of an experiment, various substances are combined with particular measures. For this reason, the study, knowledge of the name, use, function of the instruments becomes predominant.  Do not miss this list of volume measuring instruments.

What is a volume measuring instrument?

They are an object that is used to measure volume. Bliss measurement is executed by a unit or magnitude in Ml, Cc.  While other instruments are used to perform comparisons, apply predetermined formulas. They are containers or containers cataloged as containers. Because they are necessary to get values that references the states of matter. They serve to obtain the a volume measurement used in a chemical research study. They can be they are made of different materials and shapes.

List of volume measuring instruments

The instruments measuring volume II, can be made of glass material or plastic material. The names of these are: The test tube, the centrifuge tube, the graduated cylinder, the burette, the pipette, the graduated pipette, the serology pipette, the enlermeyer flask, the volumetric flask, the beaker, the kitasate flask, the micropipette, the dropper, the injector or syringe. The graduated jug, the Imhoff cone.

List of volume measuring instruments

The bureau

It is an elongated graduated container, shaped like a tube, has a uniform diameter. It consists of two ends, one open and the other closed with a glass or plastic key. The test tube is made of two types of plastic and glass, it has a small cylindrical shape. It has two ends, one closed and the other open, its bottom can be flat, round. Sometimes he uses plugs, there are some that have a graduated scale.

The centrifuge tube

They are made of glass and plastic, consist of a graduated scale, is small and cylindrical in shape. It has two ends one open and the other closed and cone-shaped. The graduated cylinder, is like a test tube but larger, is graduated because it has a scale on its walls, it has two ends one open, the other closed.

Where it has a square or hexagonal base, they are of varying size and capacity. In its mouth consists of a beak. The pipette is cylindrical in shape with two open ends, in one with a conical shape the other narrow. It is made of glass or crystal, it is a graduated instrument,

The volumetric pipette,

It is cylindrical widened in the middle with two ends one where the solution comes out, the other where it is introduced. The serological pipette consists in its form similar to the previous ones. It varies in that it has different graduations to take volume. The enlermeyer flask is made of glass with a simple scale indicated for large spaces, its mouth is wide with sloping walls. It is narrow at its mouth and wide at its base.

Volume measuring instruments function


The burette, serves to regulate the amount of liquid volume that falls from it. It measures volumes of different liquids and mass. The pipette extracts a certain amount of liquid volume to another container. The volumetric or serological pipette measures volumes of liquids with high accuracy.The enlermeyer flask is used to assemble assemblies, as a container for substances. Which will absorb prolonged energy.


The volumetric flask is used to measure exact volumes of liquids. The beaker is used in the analysis of solutions in the area of biology and chemistry. The kitasate flask, is used to do experiments such as distillation, gas collection. The micropipette is used to make concise and precise measurements.


The dropper gets a certain charge that it will subsequently empty. The syringe, the load is previously determined and then placed in a container, object or body quickly or slowly. The Imhoff cone, determine the efficiency of the decanter and the assessment of water quality.

Methodology of using the instruments to measure volume II

Measuring instruments volume II, we proceed as follows. To use it, you must verify that it is clean and dry. Note that the volume of the instrument is close to the volume to be used. If I am going to use 46 Ml I will choose a 50 ml cylinder. To take the measurement of the liquid, check the concave curvature, to have an adequate reading.

When choosing a pipette

Insert the end from under the pipette into the container with the liquid to be transferred. Start the suction with rubber knob or without it, so that if you do not have the knob. Place the index finger on the top end of the instrument and proceed to lift the finger. Letting the solution out without the tool making contact with the receiving liquid.

When you decide to work with a bureau

You have to wash it with soap and rinse it with running water three times and then wash it with distilled water. Then observe the inside of the tool to verify that bubbles are not forming on the walls, it is moistened with an even appearance or there is formation of water droplets on the walls, because if so it is dirty.

Assemble the appliance and place the material, measure that the tip does not touch the container below. Fill the burette with the ready-made standard solution, check that the key is closed, pour the titrant from above with a funnel. To go beyond the last divisions of the bureau. Open the key and let a little titrant flow to remove air.

Close the key and adjust the titrant if necessary. Write down the volume placed on the instrument. The key is manipulated with the left hand and with the right moves to the collecting beaker. Use a white paper to observe the color change.

Instruments for measuring volume, have their way of use, here's how to proceed with some so you're prepared before if you are attending the laboratory, check it everytime you can.
