What is burette and pipette?
Burette and pipette. Burette and pipette are lab equipment used in the volumetric analysis of an analyte. Burette is a glass tube having a tap at the bottom. Pipette is also a glass tube that has a bulge in the middle. They both have gradations to measure the quantity of chemical substances.

How do burettes work?
It consists of a long glass tube with a valve at one end to control the flow of liquid. Burettes serve essentially the same purpose as a pipette. Volumetric burettes are manual instruments with graduations inscribed on a glass tube. Gravity causes fluid to flow when the valve is opened.
What is the cost of burette?

Do you read a burette from bottom or top?
Refer to Figure 1 and note the correct way to read the liquid level in a buret (from the top down). Before use, a buret should always be cleaned and prerinsed with the solution to be delivered. Do NOT attempt to fill a buret precisely to the 0.00-mL mark at the top.
What does a buret measure in?
volume They measure the volume of liquid, in milliliters, the burette contains. Most burettes will hold 50 milliliters of liquid, and the scale used is generally 0.1 milliliters.
What is the shape of burette?
A burette is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet.
What is a beaker?
In chemical parlance, a beaker is a cylindrical vessel, usually of glass, with a flat bottom. This example is tall and narrow, and has a small beak (or pouring spout).
What is pipette used for?
To transport a measured volume of liquidPipette / Uses
How do you use a burette step by step?
Using a Buret
- Rinse the buret two or three times with the liquid you wish to use. …
- Clamp the buret in a buret clamp attached to a ringstand.
- Fill the buret with the liquid you wish to deliver and read the volume. …
- Slowly allow the liquid to drain into the receiving vessel.
How do you measure liquid in a buret?
Place a 100 mL graduated cylinder beneath the tip of the burette. Open the stopcock and slowly release about 40 mL of water from the burette into the graduated cylinder. Record the exact volume of water dispensed from the burette in the appropriate column of the results table.
How long is a burette?
30 in A buret (also spelled burette) is a long glass tube open at both ends, that is used to measure out precise volumes of liquids or gases. Most burets are about 0.04 in (1 mm) in diameter and 30 in (75 cm) long.
What is capacity of burette?
Laboratory Glass Burette, Capacity: 25 Ml.
Why it is necessary to rinse the burette after washing with water?
Explanation: It is important to rinse the burette after washing with water because if we use the burette without proper cleaning and rinsing then the result of the certain experiments using that burette will be inaccurate and the reading values may vary due to the droplets of water present in the burette.
How do you measure volume using a buret?

What is base burette?
Glass Buret, Base Burette (alkali burette) Burette (Volumetric burette, buret) is a volumetric measuring laboratory glassware which is used in analytical chemistry for accurate dispensing of variable, and for measuring the volume of a liquid, especially of one of the reagents in a titration.
How does a beaker look like?
Beaker – A beaker is a glass container with a flat bottom and a small spout for pouring. It is used in the chemistry lab for mixing, heating, and stirring liquids. Beakers come in various sizes and are shaped like a cylinder.
Why is a beaker shaped like that?
Beakers have a cylindrical shape, with flat bottoms so that that they can be set onto many different types of surfaces, and they usually have a thick top with a spout to make it easier to pour liquids. Beakers may be covered, perhaps by a watch glass, to prevent contamination or loss of the contents.
What is a volumetric beaker?
Volumetric glassware or volumetric flasks are containers that have been calibrated to a specific volume. These flasks, unlike Erlinmeyer flasks or beakers, are marked with lines that are calibrated to a specific volume of liquid.
What do we measure with a burette?
burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
What solution usually goes in the burette?
The titrant is the solution with known concentration and is placed in the buret. The analyte is the solution of unknown concentration that is being measured.
How do you clean a burette?
To clean the buret, use the following procedure:
- Rinse with distilled water. With the stopcock closed, add some distilled water to the buret. …
- Rinse with solution. …
- After you are finished with the buret in your experiment, rinse it by filling it with distilled water and allowing it to drain.
Why do you have to remove funnel from a burette?
Re: Taking off funnel from burette before titration? Why is it necessary to take the funnel off the burette before titration? So that any liquid present in the funnel (and there always will be) doesn't drop into the burette during the titration. This would make the initial reading false.
How does a buret work in chemistry?
In a gas burette, the stopcock is at the top; the tube of the burette is filled with a fluid, such as water, oil, or mercury, and the bottom of the tube is attached to a reservoir of the fluid. Gas is collected by displacing fluid from the burette, and the amount of gas is measured by the volume of fluid displaced.
What goes in the burette?
Use a small funnel to fill a burette with dilute hydrochloric acid. Make sure the tap at the bottom of the burette is closed before filling. Open the tap to let some acid into the part of the burette below the tap. Record the starting volume of acid in the burette.
What does a test tube look like?
A test tube is a clear glass or plastic container that is much longer than it is wide, commonly has a U-shaped bottom, and has an open top. It's essentially a cylinder-like piece of equipment with one open end.
