3 mL LDPE Pasteur Pipettes

3 mL Pasteur Pipettes for Laboratory Liquid Transfer

Puretest 3 mL LDPE Pasteur pipettes are available in four configurations: 155 mm slim, 155 mm standard, 160 mm and 182 mm. The integrated bulb and stem support manual liquid transfer without a separate bulb or pipette controller. Compare all four options on this page, then select the length and profile that suit your vessels and handling routine.

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: 155 mm slim; 155 mm standard; 160 mm standard; 182 mm extended length.
• Disposable format: use a fresh pipette when changing samples or reagents to help limit carryover.
• Clear order quantities: 100 pipettes per bag and 100 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

The two 155 mm versions are distinct designs, not duplicate listings. Identify the slim or standard profile explicitly on an inquiry. Compare these samples if access is restricted; consider 160 mm or 182 mm when overall reach is the key constraint. The 182 mm version also has a visibly different shaft and outlet profile. Verify the actual tip and shaft dimensions against your container before a bulk order.

Pipette Structure and Functional Design

Applications and Selection Guidance

General laboratory reagent transfer, aliquoting for preparation work, liquid addition to sample containers and teaching demonstrations. These disposable transfer pipettes are not interchangeable replacements for calibrated micropipettes in volume-critical assays.

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. Distinguish the two 155 mm versions on your order.
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 3 mL configuration?

Specify 3 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.
