Similarly for a burette reading ranging about 1.0 to 9.0 ml, a burette with 10 ml capacity should be used.

6.4.2 The burette should be rinsed with purified water 1-2 times and then with the volumetric

solution titrant. In case of non aqueous, burette does not rinsed with purified water,

it should only be rinsed 1-2 times with the volumetric solution titrant.

leaking from the tip.

6.5 Handling of Volumetric Pipette
6.5.1 The volumetric pipette contains the delivered volume as the specific volume of the capacity.

For transparent solutions, the lower meniscus should be considered. For colored solutions,

the upper meniscus should be considered.
6.5.4 During transfer of volume, the pipette should be held at a degree of about 30° touching

the tip of the pipette to the inner wall of the volumetric glassware.
6.5.5 Do not use volumetric pipette having scratches or any kind of stains or the marking is not

clearly visible or the tip is broken.
6.5.6 Volumetric pipettes are used for the transfer of Standard and sample solution and dilution, for

the analysis of Limit test, for the Volumetric solution preparation.

6.5 Handling of Measuring Cylinder
6.5.1 Suitable measuring cylinder should be used in different tests considering the volume. For volume

ranging from 10 to 20 ml, a cylinder with 10 ml or 25 ml capacity should be used as appropriate.
6.5.2 The lower or upper meniscus should be properly considered for different types of solutions. For

transparent solutions, the lower meniscus should be considered. For colored solutions, the upper

meniscus should be considered.
