5 mL LDPE Pasteur Pipette

5 mL Pasteur Pipettes for Laboratory Liquid Transfer

Puretest 5 mL LDPE Pasteur pipettes combine a 210 mm overall length with a built-in squeeze bulb for routine manual liquid transfer. This long-format option is useful when a shorter pipette does not provide enough reach into the intended vessel. A one-piece body keeps the bulb and stem together, with no separate controller required for operation.

Product Highlights

• LDPE construction: flexible low-density polyethylene provides a squeezable bulb and a translucent body for observing liquid during handling.
• Integrated bulb and stem: a self-contained, one-piece design operated by gently squeezing and releasing the bulb.
• Clearly identified format: 210 mm overall length; long-format design.
• Disposable format: use a fresh pipette when changing samples or reagents to help limit carryover.
• Clear order quantities: 100 pipettes per bag and 50 bags per carton simplify purchasing and stock planning.

Technical Specifications

Nominal capacity is the product size designation, not a guaranteed delivered volume or total bulb volume. These transfer pipettes are not specified as calibrated volumetric instruments.

Configurations and Packaging

Choose this 210 mm configuration when overall reach and a 5 mL nominal format match your workflow. Check the opening of the container, the required insertion depth and available handling space. The nominal capacity does not define total bulb volume, and the overall length alone does not establish how deeply the pipette can safely enter a vessel.

Pipette Structure and Functional Design

Applications and Selection Guidance

Routine reagent movement, transfer into or out of taller sample vessels, laboratory preparation and teaching demonstrations. Select this format for accessible manual transfer rather than a stated volumetric tolerance. Use calibrated pipetting equipment whenever a method requires traceable volume measurement.

Check chemical compatibility, temperature and any assay-specific cleanliness requirements before use. This page does not claim universal solvent compatibility, nuclease-free certification or suitability for every assay.

Handling and Ordering Notes

1. Select the capacity, overall length and design from the table.
2. Inspect before use. Draw liquid slowly and dispense carefully to reduce splashing; do not use mouth pipetting.
3. Use a new pipette for a new sample where carryover would affect the work. Dispose of used items under the laboratory’s applicable procedures.
4. Specify packaging and sterility requirements on the inquiry. Bulk bag packing alone does not establish sterility; any individually wrapped or sterilized supply must be confirmed for the selected configuration.

Frequently Asked Questions

How do I identify the correct 5 mL configuration?

Specify 5 mL and the exact length and design listed in the table. Include your intended container and liquid if you would like help checking the format.

Does the marked volume guarantee measurement accuracy?

No. Molded graduations are visual guides, not a stated accuracy specification. Use calibrated equipment when your protocol requires a defined measurement tolerance.

Are these pipettes individually packed or sterile?

The listed standard pack is 100 pipettes per bag. Individual wrapping, sterilization method and supporting documentation require configuration-specific confirmation; do not assume these from the photograph or bulk packing count.

What should I send for a bulk quotation?

Send capacity and length, expected order quantity, packaging or sterility requirements and destination country. For recurring supply, add estimated annual usage and any label requirements.
