Laboratory Pipette: A Precise Liquid Delivery Tool

A laboratory pipette is a scientific tool used to measure and transfer precise volumes of liquid. It’s an indispensable tool in various fields, including chemistry, biology, and medicine.

Types of Laboratory Pipettes

1. Volumetric Pipette:

   • Designed to deliver a single, fixed volume of liquid with high accuracy.
   • Often used for precise measurements in analytical chemistry.

2. Mohr Pipette:

   • Graduated pipette with markings along the side to measure various volumes.
   • Less precise than volumetric pipettes but more versatile.

3. Serological Pipette:

   • Graduated pipette with markings along the entire length, allowing for flexible volume measurements.
   • Commonly used in biological and clinical laboratories.

4. Micropipette:

   • A precision instrument used to measure and dispense microliter volumes of liquid.
   • Essential for molecular biology, biochemistry, and other fields requiring high precision.

Key Considerations When Using Pipettes:

• Calibration: Regular calibration is crucial to ensure accurate measurements.
• Proper Technique: Correct pipetting technique, including proper tip immersion and aspiration, is essential.
• Tip Selection: Choose pipette tips that are compatible with the pipette and the liquid being transferred.
• Maintenance: Clean pipettes regularly to prevent contamination and ensure optimal performance.

By understanding the different types of pipettes and their proper use, scientists can perform precise liquid handling tasks, leading to accurate and reliable experimental results.
