PRODUCT DETAILS

2 mL Pasteur Pipettes for Laboratory Liquid Transfer

The Puretest 2 mL LDPE Pasteur pipette combines a 140 mm overall length with an integral squeeze bulb for everyday liquid-transfer tasks. This intermediate-capacity format is a useful option when a 1 mL pipette is too small for the intended transfer, but the reach and size of a larger model are unnecessary.

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: 140 mm standard.
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.

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

Capacity	Overall length	Design	Pipettes / bag	Bags / carton	Pipettes / carton
2 mL	140 mm	Standard	100	100	10,000

This page covers the 2 mL, 140 mm configuration only. Use the overall length to assess reach into your container, and check the opening against the tapered shaft. Nominal capacity alone does not establish fit. Evaluate the actual liquid and required transfer volume before choosing a dispensing technique.

Pipette Structure and Functional Design

Component	Practical function
Integral squeeze bulb	Gently compress before aspiration, release to draw liquid, then squeeze to dispense. No separate bulb is needed.
Translucent LDPE body	Allows the liquid level and visible bubbles to be observed during routine handling.
Molded stem and tapered outlet	Guide liquid into the receiving vessel. Select the shaft profile and overall length for the container geometry.
Reference graduations	Assist visual estimation. Drop size and delivered volume depend on the liquid, angle, squeeze pressure and selected design.

Applications and Selection Guidance

Routine reagent dispensing, moving liquid between laboratory vessels, sample preparation and educational laboratory work. The integrated bulb supports straightforward manual handling without a separate controller.

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

Select the capacity, overall length and design from the table.
Inspect before use. Draw liquid slowly and dispense carefully to reduce splashing; do not use mouth pipetting.
Use a new pipette for a new sample where carryover would affect the work. Dispose of used items under the laboratory’s applicable procedures.
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 2 mL configuration?

Specify 2 mL and 140 mm overall length. 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.
