Mahtpipetid omavad suurt pirnikujulist osa, mille ülalpool on pikk kitsas osa ja millel on üks gradueerimismärk, mis on kalibreeritud ühe ruumala väärtuse jaoks vastavalt (1, 2, 5, 10, 20, 25, 50 või 100) ml.
Volumetric pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume (like a volumetric flask). Typical volumes are 1, 2, 5, 10, 20, 25, 50 and 100 mL.
