What is burette calibration?

Calibration of a burette and pipette is carried out by measuring the mass of a known volume of water delivered by the burette or the pipette. By knowing the temperature and the density of water at that temperature, the true volume delivered by the burette or the pipette is calculated.

What is burette method?

A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined.

How do Burets work?

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 is pipette calibration?

The calibration of pipette is carried out by gravimetric method. When determining the volume of water, the accuracy of measurements is effected by ambient temperature, atmospheric pressure and relative humidity. These factors are usually combined to give the Z factor, used in calculation of volume of water.

How is the volume of a burette determined?

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. On a liquid burette, the stopcock is at the bottom, and the precise volume of the liquid dispensed can be determined by

How is the calibration of pipettes and burettes done?

Calibration of Pipettes and Burettes. This experiment sought to gather data regarding water volume gathered in glassware, then to statistically analyze the data, focusing on average and standard deviation, along with relative error gleaned from linear regression. This experiment was divided into two parts.

What is the purpose of volumetric glassware calibration?

1. Purpose. The purpose of this procedure is to provide a method for the calibration of volumetric glassware. 2. Scope. The scope includes volumetric glassware (i.e. designed to contain or deliver an accurate volume of solution), including pipettes, volumetric flasks and burettes.
