Graduated pipettes, glass

Pipettes with capacity graduation are used to dispense liquids. They are calibrated ”Ex” (to deliver): the imprinted volume refers to the delivered amount of liquid. Graduated pipettes for complete delivery are called serological pipettes.

Amber graduation: the amber stain graduation penetrates into the glass surface and is, therefore, more resistant than a blue, fused-on enamel graduation.
