Volumetric Pipette
Volumetric pipettes are precision glass instruments used to deliver a single, fixed volume of liquid with the highest accuracy. Calibrated to Class A or B standards, these pipettes feature a bulb-shaped center and are ideal for analytical chemistry, titrations, and solution preparation.
Made from borosilicate glass, they are available in capacities ranging from 1 mL to 100 mL, ensuring repeatable and accurate measurements in pharmaceutical, chemical, and research laboratories.
FAQs:
Q1. What is a Volumetric Pipette?
A volumetric pipette is a laboratory glassware instrument designed to measure and transfer a fixed, precise volume of liquid. Unlike graduated pipettes, it has a single calibration mark for accuracy, making it ideal for analytical chemistry and titration experiments.
Q2. What is the use of a Volumetric Pipette?
Volumetric pipettes are mainly used in:
-
Quantitative chemical analysis
-
Titration experiments
-
Preparation of standard solutions
-
Pharmaceutical, academic, and research laboratories
Q3. What is the difference between Class A and Class B Volumetric Pipettes?
-
Class A Volumetric Pipettes: High-precision, certified for analytical and research use, with tighter tolerance.
-
Class B Volumetric Pipettes: Lower accuracy, suitable for general laboratory and educational purposes.
Q4. How does a Volumetric Pipette differ from a Graduated Pipette?
-
Volumetric Pipette: Calibrated to deliver one fixed volume with high accuracy.
-
Graduated Pipette: Has multiple graduation marks, allowing measurement of different volumes but with slightly less precision.
Q5. What materials are used for Volumetric Pipettes?
Volumetric pipettes are usually made from borosilicate glass for chemical resistance and accuracy. Some modern versions are also made from plastic (polypropylene or polystyrene) for single-use applications.
Q6. How do you use a Volumetric Pipette correctly?
-
Use a pipette filler or bulb to draw liquid (never by mouth).
-
Fill the pipette slightly above the calibration mark.
-
Adjust until the meniscus touches the calibration mark.
-
Dispense the liquid smoothly into the receiving vessel.
Q7. How do you clean and maintain Volumetric Pipettes?
-
Rinse with distilled water after each use.
-
Use neutral detergents if needed.
-
Avoid scratches and sudden temperature changes.
-
Store in a vertical rack to prevent damage.
