Disposable PE Pasteur Pipette for Liquid Transfer

Pasteur pipette is a laboratory consumable designed for the aspiration, transfer, and dispensing of small liquid volumes, commonly used in cell culture, microbiology, clinical diagnostics, sample processing, and routine liquid transfer operations. The product is typically a plastic Pasteur pipette made from PE material, featuring softness, light weight, and breakage resistance, suitable for single use to minimize cleaning requirements and reduce the risk of cross-contamination.

Structure

The Pasteur pipette mainly consists of the pipette body, pipette tip, bulb, and graduated area.

Body: Slim and flexible, facilitating insertion into centrifuge tubes, test tubes, culture vessels, and other small-diameter containers.
Pipette Tip: The front end is finer, allowing controlled uptake and dispensing of liquids, suitable for small-volume liquid transfer.
Bulb: Integrated with the pipette body, enabling liquid uptake and discharge by squeezing and releasing, without the need for an additional suction bulb.
Graduated Area: Some specifications feature clear graduations to facilitate approximate judgment of the transferred liquid volume.

Features

Smooth aspiration and dispensing. The tube body rebounds steadily, enabling liquid uptake and dispensing with light pressure, suitable for high-frequency liquid transfer operations.
Controllable dropwise dispensing. The fine pipette tip provides more focused liquid delivery, facilitating small reagent additions and dropwise operations.
Flexible liquid handling. The soft tube body can be gently bent, making it easy to operate in narrow-necked or deep containers.
Less residue. The smooth inner wall helps reduce liquid clinging, improving sample transfer efficiency.
Multiple packaging types. Available in bulk, single units in paper-plastic packaging, and single units in plastic-plastic packaging.
Cleanliness control. Provides irradiated sterilization and non-sterilized options; irradiated sterilization meets SAL 10⁻⁶ standards and is free of DNase, RNase, and endotoxins.

Applications

Pasteur pipettes are suitable for aspirating, transferring, dispensing, and aliquoting small volumes of liquid in laboratories and are commonly used in the following situations:

Liquid transfer: Used to transfer small amounts of liquid between containers such as test tubes, centrifuge tubes, and petri dishes.
Dropwise addition: Suitable for adding small amounts of reagents, buffers, or samples dropwise.
Sample handling: Can be used for supernatant aspiration, sample dilution, mixing, and aliquoting.
Cell experiments: Can be used for transferring culture media, aliquoting cell suspensions, and handling liquids in petri dishes.
Routine experimental operations: Suitable for liquid handling in microbiology, molecular biology, clinical testing, and basic chemistry experiments.
