Manual Pipettes are handheld liquid-handling instruments used to aspirate and dispense precise volumes of liquids in laboratory applications. Operated by a plunger mechanism, they allow accurate and repeatable transfer of small liquid volumes, typically ranging from microliters to milliliters. Available in fixed-volume or adjustable-volume designs, manual pipettes are widely used in biological, chemical, and clinical laboratories for sample preparation, titration, and analytical procedures. They are valued for their simplicity, reliability, and ease of use.
