The specifications that point out: its utmost volume is printed on the neck with the pipette; the dimensions of their divisions, represented as one/10, one/one hundred; the calibration temperature; along with a legend determined as TD or TC, from the acronym in English of To Shipping and delivery (ex) or To Have (in), which suggests to pour or empty, respectively. On top of that, the technical specs point out the temperature at which the pipette was calibrated.
A vital laboratory Software, starting from volumetric used in chemistry for specific measurements to air displacement versions.
