Pasteur Pipette Product Introduction

Pasteur pipettes are disposable plastic liquid transfer tools widely used in laboratories. Made of safe, transparent polyethylene, they feature clear scales for easy volume observation and precise liquid handling.


They are designed for safe transfer, extraction, and dropping of small volumes of liquids, effectively preventing cross-contamination. Flexible and easy to use, they are widely applied in clinical testing, molecular biology, teaching experiments and daily lab work.


Sterile and non-sterile types are available, providing stable and reliable performance for various scientific and testing operations.


Pasteur Pipette – Product Features & Advantages

1. High-Quality Medical-Grade Material

Our pasteur pipettes are made of non-toxic, transparent polyethylene (PE) material, ensuring excellent chemical resistance and stability. They are safe for human body fluids, reagents, and biological samples, with no harmful substances released during use. Each pipette is strictly tested to meet international laboratory safety standards.

2. Clear Scale & Precise Liquid Control

The pasteur pipette has clear, printed graduation lines for easy and accurate volume reading. The optimized dropper design enables smooth liquid absorption and stable dropping, effectively reducing liquid residue. It supports precise transfer of small volumes, greatly improving the accuracy of experiments and sample handling.

3. Flexible & Easy Operation

With a soft, elastic bulb and smooth stem, our pasteur pipettes offer comfortable one-handed operation. Users can easily control liquid flow without additional equipment. The lightweight and simple structure improves work efficiency, making them ideal for rapid sample transfer in clinical, teaching, and daily laboratory environments.

4. Disposable & Anti‑Contamination Design

These are disposable pasteur pipettes that effectively avoid cross-contamination between samples. They are individually inspected to ensure cleanliness. Sterile versions are also available, free of DNase, RNase, and pyrogens, providing reliable protection for sensitive experiments such as cell culture and diagnostics.

5. Wide Compatibility & Versatile Applications

Suitable for use in laboratories, hospitals, schools, and research centers. Our pasteur pipettes are widely used for sample transfer, reagent addition, liquid separation, and specimen preparation. Available in multiple capacities to meet different experimental needs, they are essential and practical consumables for daily use.


Application Scenarios of Pasteur Pipette

1. Clinical and Medical Testing

Pasteur pipettes are widely used in hospitals and clinics for transferring blood, urine, saliva and other biological samples. They help with safe sample handling and reagent preparation, ensuring accurate and contamination‑free diagnostic procedures.

2. Molecular Biology and Cell Culture

In biological laboratories, they are ideal for transferring liquids in cell culture, media preparation, and sample separation. Their soft design ensures gentle handling to protect cells and biomolecules without damage.

3. Educational Laboratory Teaching

Widely used in schools and training centers for chemistry and biology experiments. Easy to operate and safe for students, pasteur pipettes support basic liquid transfer, observation, and demonstration experiments.

4. Food and Cosmetic Testing

Applied in sample pretreatment for food safety, cosmetics, and environmental monitoring. They allow safe and precise transfer of small‑volume samples, improving the reliability of testing and analysis.

5. Daily Laboratory Routine Work

Suitable for routine liquid transfer, sampling, mixing, and dispensing in labs. Disposable and lightweight, pasteur pipettes improve efficiency and reduce cross‑contamination in daily operations.


How to Use Pasteur Pipette

Hold the pipette vertically and gently squeeze the rubber bulb to release air. Immerse the tip into the liquid, then slowly loosen the bulb to draw liquid. Control the flow by gently pressing the bulb for accurate dropping. After use, dispose of the pipette properly to avoid contamination. Simple operation ensures safe and efficient liquid handling every time.
