Uncertainties for Volumetric Glassware
Volumetric glassware, such as pipettes, burettes, and flasks, is required when performing any analytical determinations. This page provides a table of typical uncertainty values for the calibrated volume of such glassware. Since these are based on the mean and standard deviation of the volumes delivered for a batch of glassware, they are treated as random errors.
Note that actual errors in volume can be much larger than suggested by these uncertainties if the glassware is dirty, or used incorrectly. This could be considered as a source of gross error in the resulting values.
|Item||Volume (mL)||Uncertainty (mL)|
|Mohr (graduated) pipette||10.00||±0.05|
