Cylinder, Pipette and Burette





A cylinder is the one of the most curvilinear geometric shapes,
the surface formed by the points of a fixed distance from a given straight line, the axis of a cylinder.



Pipette are devices that allow the users to extract or deliver small amount of liquid.
A pipette uses a bulb to dispense appropriate quantities of effluent.




A burette is a vertical piece of cylindrical piece of laboratory glassware with volumetric graduation on its full length and a presicion tap, or a stopcock, on the bottom . It is used to dispense known amouts of liquid regents in experiments which such precision is necessary.
The difference between the cylinder, pipette and the burette.
They measure volumes of liquids, however,
1)The burette has a tap to control the flow of liquid while the cylinder and the pipette do not have. a
2)The pipette uses a bulb to dispense appropriate quantities of liquid
3) The measuring cylinder is a graduated container with a spout unlike the pipette and burette.

  1. Pasteur Pipettes: These are made of glass so that one can get a clear view of the liquid being transferred. They are reusable with the pasteurization process that is affected for cleaning.
