What is mean by burret?

Definition of burette : a graduated glass tube with a small aperture and stopcock for delivering measured quantities of liquid or for measuring the liquid or gas received or discharged.

Why are burettes used?

A burette is used to dispense small volumes of liquid called aliquots, or sometimes gas, with high accuracy. 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.

What is the use of stopcock in burette?

At the tip of burette, there are a stopcock and valve to control the flow of the chemical solution. The barrel of the stopcock can be made of glass or the plastic PTFE. Stopcocks with glass barrels need to be lubricated with vaseline or a specialized grease.

How do Americans say pipette?

Tips to improve your English pronunciation: Break ‘pipettes’ down into sounds: [PI] + [PETS] – say it out loud and exaggerate the sounds until you can consistently produce them.

How do burettes work?

What is the difference between a pipette and a buret?

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.

Why do you think you fill the burette above the zero mark?

The meniscus, the bottom of the water level in the burette, should be level with the zero mark. Filling the burette this way is also useful because it means the space under the tap is also filled with liquid. This is important, as the burette is calibrated to include this volume.

How do you remove air bubbles from the burette?

Check the tip of the buret for an air bubble. To remove an air bubble, whack the side of the buret tip while solution is flowing. If an air bubble is present during a titration, volume readings may be in error. Rinse the tip of the buret with water from a wash bottle and dry it carefully.
