A micropipette is one of the most essential tools in modern laboratories, designed for precise liquid handling and accurate volume measurement. At AHN Biotechnologie, we specialize in creating high-performance micropipettes that support research, diagnostics, and industrial applications with unmatched reliability and accuracy.

In this detailed guide, we will explore everything about micropipettes: their types, working principles, applications, maintenance tips, and why AHN Biotechnologie is a trusted name for laboratory equipment worldwide.

What is a Micropipette?

A micropipette (Mikropipette) is a precision instrument used to measure and transfer small liquid volumes, usually in the microliter (µL) range. Unlike traditional pipettes, micropipettes are engineered with advanced calibration and ergonomic designs to ensure high accuracy and reproducibility in experimental results.

These instruments are vital in molecular biology, microbiology, biochemistry, pharmaceuticals, and medical diagnostics, where even the smallest deviation can affect outcomes.

Types of Micropipettes

Micropipettes come in various forms depending on laboratory needs. At AHN Biotechnologie, we provide micropipettes tailored for accuracy, durability, and comfort.

1. Fixed Volume Micropipettes

  • Delivers a single, pre-set volume with maximum precision.

  • Ideal for routine applications where the same volume is repeatedly required.

  • Reduces error rates in PCR, ELISA, and clinical testing.

2. Variable Volume Micropipettes

  • Adjustable range for different liquid volumes.

  • Suitable for diverse applications requiring flexibility.

  • Ensures ease of use and efficiency in multi-step laboratory protocols.

3. Single-Channel Micropipettes

  • Designed for handling one sample at a time.

  • Perfect for DNA analysis, protein quantification, and cell culture experiments.

4. Multi-Channel Micropipettes

  • Available in 8-channel and 12-channel versions.

  • Speeds up work in microplate assays, 96-well plates, and high-throughput testing.

  • Maintains precision even with rapid sample processing.

5. Electronic Micropipettes

  • Digital control ensures greater precision and reduced hand strain.

  • Equipped with multiple dispensing modes.

  • Highly recommended for long working hours and repetitive pipetting tasks.

Working Principle of a Micropipette

The micropipette operates using an air displacement mechanism. When the plunger is pressed, air inside the barrel is displaced, creating a vacuum that draws liquid into the disposable pipette tip. Upon releasing the plunger, the liquid is dispensed with exact precision.

At AHN Biotechnologie, our micropipettes are designed with high-quality piston systems that minimize leaks, provide smooth operation, and ensure long-lasting calibration stability.

Applications of Micropipettes

Micropipettes are indispensable across multiple industries. Some common applications include:

  • Molecular Biology: DNA extraction, PCR amplification, electrophoresis sample preparation.

  • Clinical Diagnostics: ELISA testing, blood analysis, serum and plasma handling.

  • Pharmaceuticals: Drug formulation, quality control, and analytical testing.

  • Biochemistry: Protein quantification, enzyme assays, and metabolic studies.

  • Microbiology: Sample inoculation, bacterial culture preparation, and media transfer.

  • Food & Beverage Industry: Quality assurance, contamination testing, and additive measurement.

How to Use a Micropipette Correctly

Correct usage ensures accuracy and prevents contamination. Follow these steps:

  1. Set the desired volume (for variable micropipettes).

  2. Attach a sterile pipette tip firmly.

  3. Press the plunger to the first stop before immersing the tip in liquid.

  4. Slowly release the plunger to aspirate liquid.

  5. Dispense the liquid by pressing the plunger to the second stop.

  6. Eject the tip using the tip ejector button.

Maintenance and Care of Micropipettes

Proper maintenance extends the life and performance of micropipettes.

  • Regular Calibration: Essential for ensuring accuracy in research.

  • Clean After Use: Prevents contamination and clogging.

  • Use Compatible Tips: Always choose high-quality, recommended tips.

  • Store Upright: Prevents liquid from entering the internal mechanism.

  • Check Seals & O-Rings: Replace if worn out to avoid leakage.
