When it comes to transferring small volumes of liquid with accuracy and ease, the Pasteur pipette is a staple in laboratories worldwide. But what happens when you need a little more precision? Enter the graduated Pasteur pipette - a simple yet highly effective tool that combines the flexibility of a traditional Pasteur pipette with the added benefit of volume markings along its length. Unlike standard Pasteur pipettes, which are unmarked and used for qualitative transfers, graduated versions allow users to estimate and dispense specific volumes of liquid, making them ideal for semi-quantitative work.
The volume graduations on a graduated Pasteur pipette enable users to measure and transfer approximate volumes with greater confidence. This is especially useful for protocols that require consistent aliquoting or serial dilutions, where reproducibility is key.
Graduated Pasteur pipettes are suitable for a wide range of laboratory tasks, including:
Available in both glass and plastic, graduated Pasteur pipettes can be single-use (to prevent cross-contamination) or reusable, depending on your application and budget. Their affordability makes them a practical choice for busy labs.
The slim, tapered design enables precise control, while the graduations provide a visual guide for accurate volume estimation.
Disposable plastic graduated Pasteur pipettes are ideal for applications where sterility is essential, such as cell culture or clinical diagnostics. Use once and discard to minimise contamination risks.
When selecting a graduated Pasteur pipette, consider:
Graduated Pasteur pipettes are a versatile and cost-effective solution for laboratories that need a balance between precision and convenience. Whether you’re performing routine transfers, preparing samples, or working in a sterile environment, these pipettes offer the flexibility and reliability you need.
