PRODUCT DETAILS

1 mL Pasteur Pipettes for Laboratory Liquid Transfer

Puretest 1 mL LDPE Pasteur pipettes provide a simple, self-contained way to pick up and dispense small liquid quantities. Choose a compact 90 mm format for short-reach work or a 145 mm or 160 mm version when access into a deeper vessel matters. All three lengths are grouped here so buyers can compare geometry without moving between separate listings.

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: 90 mm compact; 145 mm standard length; 160 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

Capacity	Overall length	Design	Pipettes / bag	Bags / carton	Pipettes / carton
1 mL	90 mm	Compact	100	100	10,000
1 mL	145 mm	Standard length	100	100	10,000
1 mL	160 mm	Extended length	100	100	10,000

Match the pipette to the container, not just the nominal volume. The 90 mm version offers a compact working length; the 145 mm and 160 mm versions provide progressively longer reach. Bulb and shaft geometry also differ, so a sample comparison is useful before standardizing one format.

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

Small-volume reagent addition, transfer between sample vessels, teaching laboratory demonstrations and routine preparation work where the purpose is liquid transfer rather than a certified volumetric 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

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 1 mL configuration?

Specify 1 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.
