Reference 2 Single-Channel Variable Volume Pipette

The Reference® 2 variable volume single-channel pipette from Eppendorf enables precise and reproducible dosing, tailored to the demanding requirements of laboratories. Thanks to its multifunctional push button, it offers intuitive volume adjustment, smooth aspiration and reliable tip ejection. Designed for optimal user comfort and durability, it is compatible with epT.I.P.S. tips and covers volumes from 0.1 µL to 10 mL. Autoclavable and UV-sterilisable, it is available in several colour-coded models to meet the varied needs of everyday scientific protocols.



Description

Reference® 2 Single-Channel Variable Volume Pipettes – Flexible Precision for the Laboratory

The Eppendorf Reference® 2 single-channel variable volume pipette has been designed to meet the precision, flexibility and reliability requirements of the most demanding laboratory environments. Operating on an air cushion principle, it allows dosing without contact between the liquid and the internal components, ensuring better hygiene and simplified maintenance. Its adjustable volume range, depending on the model, offers great versatility in everyday liquid handling tasks. It is suitable for both routine tasks and more specific protocols requiring a wide range of volumes.

Equipped with an intuitive and secure volume locking system, it prevents handling errors and guarantees reproducible results. Its multifunction push button allows the volume to be adjusted, the liquid to be aspirated, dispensed and the tip ejected, while reducing user effort. This ergonomic design allows for a natural grip, suitable for long pipetting sessions, without causing strain on the wrist or fingers.

The components of the Reference 2 are made of robust, chemical-resistant materials: refined polypropylene, PVDF, PEI, stainless steel , etc. This choice not only ensures the device's long service life, but also protects it from aggressive agents commonly used in laboratories. Each pipette is also equipped with an integrated RFID chip, enabling traceability and integration into equipment management systems.

The Reference® 2 is fully autoclavable (at 121°C for 20 minutes) without the need for prior disassembly. It is also UV sterilisable, making it ideal for environments requiring a high level of hygiene, such as microbiology, molecular biology and quality control laboratories.

Its design is also optimised for thorough cleaning. The lower body can be dismantled, allowing direct access to critical components for maintenance or decontamination operations. Compatible with epT.I.P.S. tips, it ensures a perfect fit to limit volume loss and enhance dosing accuracy.

Whether for one-off applications or long series, the Reference® 2 pipette is a reliable, robust and comfortable tool that helps improve experimental rigour and laboratory efficiency.
