A volumetric pipette is a precision instrument used for accurately measuring and delivering specific volumes of liquids. It is typically made of high-quality borosilicate glass, known for its resistance to chemical attack and thermal expansion. The pipette has a long, narrow stem with a bulb in the middle, and a single calibration mark on the stem. This calibration mark indicates the exact volume that the pipette is designed to deliver.

Volumetric pipettes are used in a wide range of laboratory applications, including preparing solutions with precise concentrations, performing titrations, and conducting various analytical procedures. Their accuracy is critical in many scientific experiments and industrial processes. To use a volumetric pipette, the liquid is drawn up into the pipette using a pipette bulb or filler until the meniscus (the curved surface of the liquid) reaches the calibration mark. The liquid is then carefully dispensed into the receiving vessel, ensuring complete drainage.

Usage of Volumetric Pipette:

  • Precise Volume Measurements: Accurately measure and deliver specific volumes of liquids in various laboratory procedures.
  • Analytical Chemistry: Essential for preparing solutions with precise concentrations.
  • Titrations: Used to accurately deliver titrant solutions during titration experiments.

How to Use Volumetric Pipette:

  • Cleaning: Thoroughly clean the pipette before and after use to ensure accurate measurements.
  • Filling: Draw the liquid into the pipette using a pipette bulb or filler, ensuring the meniscus reaches the calibration mark.
  • Dispensing: Carefully dispense the liquid from the pipette, ensuring complete drainage.
  • Calibration: Regularly calibrate volumetric pipettes to maintain accuracy.

Volumetric pipettes require careful handling and proper cleaning to maintain their accuracy. Regular calibration is also essential to ensure that the delivered volume remains within the specified tolerance.
