A pipette typically consists of a narrow, elongated tube with a tapered tip. The body of the pipette may be graduated (marked with measurement lines) to indicate various volumes of liquid. The top of the pipette usually features a mechanism for drawing liquid, such as a plunger, bulb, or motorized mechanism in the case of electronic pipettes. Pipettes are generally made of glass or durable plastic, and their appearance can vary depending on the type: manual pipettes may have a simple design with a handle and plunger, while electronic pipettes have a more complex design with buttons for volume adjustment and an electronic readout.
