AELAB | Laboratory Equipment | Pipette Manual
A Manual Pipette is an essential laboratory instrument for precise liquid handling. Used across biological, chemical, and diagnostic labs, manual pipettes offer exceptional accuracy, affordability, and control. Despite increasing automation, they remain a cornerstone of scientific precision and repeatable measurements.
A manual pipette is a hand-operated air displacement device used to aspirate and dispense measured liquid volumes. It typically includes a plunger button, volume adjustment knob, tip ejector, and shaft for attaching disposable tips. Available in various configurations, manual pipettes support routine and advanced applications in research, diagnostics, and industrial quality control.
