FAQ

What is a disposable glass Pasteur pipette used for?

A disposable glass Pasteur pipette is designed for non-volumetric liquid transfer in laboratory workflows. This 2 mL borosilicate glass Pasteur pipette is commonly used for cell culture media handling, PBS transfer, reagent dispensing, sample preparation, microbiology procedures, and general laboratory liquid handling applications.

What are the advantages of using a borosilicate glass Pasteur pipette?

Made from high-purity 3.3 borosilicate glass, this disposable Pasteur pipette provides excellent chemical resistance, thermal stability, and low extractables. The glass material helps minimize potential interference from released ions and is suitable for sensitive laboratory applications, including cell culture and analytical workflows.

Is this 2 mL glass Pasteur pipette sterile?

This product is a non-sterile disposable glass Pasteur pipette. For applications requiring sterile handling, such as cell culture workflows, the pipettes can be sterilized before use according to established laboratory procedures.

What is the difference between a Pasteur pipette and a volumetric pipette?

A Pasteur pipette is designed for transferring liquids rather than accurately measuring a specific volume. This 2 mL Pasteur pipette is ideal for controlled liquid transfer, reagent addition, and sample handling, while volumetric pipettes are intended for precise volume measurement applications.

Can this 9 inch glass Pasteur pipette be used for cell culture applications?

Yes. The 9 inch disposable glass Pasteur pipette is commonly used in cell culture laboratories for media transfer, buffer washing, trypsinization procedures, and small-volume reagent handling. Its borosilicate glass construction provides reliable performance in biological research workflows.

What features improve the usability of this disposable Pasteur pipette?

This pipette features a fire-polished opening for smooth bulb attachment and a straight-cut tip for consistent liquid dispensing. The design supports safe handling, stable transfer performance, and convenient use in routine laboratory procedures.

What applications are suitable for non-sterile glass Pasteur pipettes?

Non-sterile glass Pasteur pipettes are widely used in microbiology, bacteriology, immunology, hematology, serology, clinical chemistry, and molecular biology research. They are suitable for general-purpose liquid transfer where precise volumetric measurement is not required.

How are disposable borosilicate glass Pasteur pipettes packaged?

These disposable Pasteur pipettes are supplied in bulk packaging with 1000 pipettes per case (4 packs of 250 pipettes). The bulk format is suitable for laboratories requiring a reliable supply of single-use glass transfer pipettes.
