Pasteur Pipettes Singapore: Glass & Plastic Transfer Pipettes Guide
The Pasteur pipette is one of the most fundamental and versatile tools in any laboratory — a simple glass or plastic tube used to transfer small volumes of liquid drop by drop. From cell culture media handling to reagent dispensing in wet chemistry, Pasteur pipettes are a daily staple in Singapore laboratories across research, clinical, and teaching settings.
At JW RESEARCH SUPPLY, we supply Singapore laboratories with glass and plastic Pasteur pipettes in bulk. This guide covers the material choices, capacity options, sterility, and safe-handling practices that help you choose the right pipette for every task.
Glass vs Plastic Pasteur Pipettes
The choice between glass and plastic comes down to chemical compatibility, reusability, and sterility requirements:
- Glass Pasteur Pipettes — Made from borosilicate or soda-lime glass, they are reusable, heat-resistant, and compatible with most organic solvents. They can be autoclaved and are the traditional choice for solvent transfer and flame-sealing applications.
- Plastic Transfer Pipettes — Made from low-density polyethylene (LDPE), they are disposable, flexible, and unbreakable. They are available pre-sterilised and are ideal for cell culture, microbiology, and single-use workflows.
Pasteur Pipette Specifications
| Material | Capacity | Sterility | Reusable | Chemical Resistance | Typical Application |
|---|---|---|---|---|---|
| Borosilicate Glass | 1 – 5 mL | Non-sterile | Yes | Excellent | Solvent transfer, autoclaved use |
| Soda-Lime Glass | 1 – 5 mL | Non-sterile | Yes (limited) | Good | General chemistry, teaching |
| LDPE Plastic | 1 – 5 mL | Sterile / Non-sterile | No | Moderate | Cell culture, microbiology, single-use |
Selection Criteria
- Chemical compatibility — Choose glass for aggressive solvents; plastic for aqueous and biological samples.
- Sterility requirement — Use gamma-sterilised plastic pipettes for sterile cell culture work.
- Capacity — Match the pipette volume (1–5 mL) to your transfer volume.
- Tip style — Fine tips for precise drop control; wider or graduated tips for faster dispensing.
- Budget and throughput — Disposable plastic is economical at scale; glass is cost-effective when reused.
Safe Handling Best Practices
- Use a pipette bulb or pump — Never mouth-pipette, even for non-hazardous liquids.
- Inspect glass pipettes — Discard any with chips or cracks to avoid breakage and injury.
- Handle glass carefully — Dispose of broken glass in designated sharps containers.
- Avoid cross-contamination — Use single-use plastic pipettes for sensitive or hazardous samples.
- Sterilise before reuse — Autoclave glass pipettes thoroughly between uses.

Frequently Asked Questions
Q: What is the difference between glass and plastic Pasteur pipettes?
Glass Pasteur pipettes are reusable, heat-resistant, and chemically compatible with most solvents, making them ideal for solvent transfer and applications requiring autoclaving. Plastic (polyethylene) transfer pipettes are disposable, flexible, and unbreakable, and are available pre-sterilised for cell culture and microbiology work. Choose glass for chemical compatibility and reusability, plastic for convenience and sterility.
Q: Are Pasteur pipettes sterile and DNase/RNase-free?
Sterile plastic Pasteur pipettes are available gamma-sterilised, individually wrapped, and certified DNase/RNase-free, pyrogen-free, and endotoxin-free for molecular biology and cell culture. Glass Pasteur pipettes are typically supplied non-sterile and should be autoclaved before use in sterile applications. Always verify the certification for your specific batch.
Q: How do I choose the right Pasteur pipette volume?
Pasteur pipettes commonly come in 1 mL, 2 mL, 3 mL, and 5 mL capacities. Short-form and long-form options are available. For precise small-volume transfers, 1–2 mL pipettes offer the best control; for larger transfers or when a longer reach is needed, choose 3–5 mL pipettes. Match the tip diameter to your application — fine tips for controlled drops, wider tips for faster transfer.
Q: Can glass Pasteur pipettes be reused?
Yes, glass Pasteur pipettes can be washed and reused, but they must be thoroughly cleaned and autoclaved between uses to prevent cross-contamination. Inspect tips for chips or cracks before each reuse, as damaged pipettes can break during handling. For single-use convenience and guaranteed sterility, disposable plastic transfer pipettes are often more cost-effective in high-throughput settings.
