Pasteur Pipette

Pasteur pipettes are single-use disposable pipettes made from LDPE for reliable liquid transfer in analytical and routine laboratory workflows. Available in 1 ml, 3 ml, 5 ml and 10 ml volumes, they are designed for low-cost, low-extractable handling of aqueous and mild organic solutions. The tapered tip allows for precise dispensing without the need for calibration, and the flexible body enables easy aspiration by mouth or with a bulb. They are supplied in bulk packaging to support high-throughput operations.

How It Is Made

Manufacturing And Quality Control

Manufacturing Process

LDPE extrusion into tubing
Cutting to specified lengths for each volume
Tapering the tip using heat or mechanical shaping
Bulk packing into cases of 3000 or 5000 pieces
Labeling with part number and volume on the case

Quality Control

Visual inspection of each pipette for defects or irregularities
Volume consistency verified by sample testing across batches
Material integrity checked to ensure LDPE is free from contaminants
Packing quantity verified per case before dispatch

Comparison

Compared With The Alternatives

Versus Glass Pasteur pipettes

LDPE pipettes are disposable and eliminate cleaning and sterilisation steps, reducing contamination risk and labour cost

Versus Reusable plastic pipettes

Disposable LDPE pipettes avoid carry-over and the need for cleaning, which is critical in sensitive analytical workflows

Versus Calibrated serological pipettes

Pasteur pipettes are not calibrated, which reduces cost and is sufficient for non-quantitative transfers where precision is not required

Versus Glass Pasteur pipettes with rubber bulbs

LDPE pipettes are safer for mouth aspiration as they are less prone to breakage and do not pose glass shard risk

Use Guide

How To Use It

Select the volume size based on the transfer requirement: 1 ml for small volumes, 10 ml for larger transfers
Attach a bulb or use mouth aspiration to draw liquid into the pipette
Dispense by gently squeezing the bulb or releasing pressure from the mouth
Discard after one use to prevent cross-contamination
Do not use with highly aggressive solvents beyond LDPE compatibility
Store in a dry, clean environment to prevent dust or debris contamination

FAQ

Questions Buyers Ask

What volumes are available for Pasteur pipettes?

Available in 1 ml, 3 ml, 5 ml, and 10 ml volumes.

How are they packed?

Packed in cases of 5000 pieces (1 ml, 3 ml, 10 ml) or 3000 pieces (5 ml).

Are these pipettes calibrated?

No, Pasteur pipettes are not calibrated. They are intended for non-quantitative transfer.

Can I use these for organic solvents?

They are suitable for aqueous and mild organic solvents. Avoid highly aggressive solvents that may degrade LDPE.

Do you offer private-label packaging?

Yes. The OEM division supports private-label printing on packaging cases and custom volume orders.
