Manual pipettes are laboratory instruments used for accurate transfer and measurement of liquid volumes by hand. They rely on a suction and displacement mechanism, such as a piston or bulb, to aspirate and dispense liquids. These pipettes are widely used in chemical, biological, and medical laboratories for tasks requiring precision and repeatability.
They are available in various types, including volumetric, graduated, and serological pipettes, allowing selection based on the required volume range and accuracy. Manual pipettes are valued for their simplicity, durability, and cost-effectiveness.
