Eppendorf Combitips Plus 0.5 ml 6 Packs with 10 Tips Each - 60 Combitips

Eppendorf 2226720-5 (0030069225) Combitips Plus 0.5 ml Dispenser Tips

The Eppendorf 2226720-5 is a 0.5 ml precision dispenser tip engineered for use with the Eppendorf Multipette® (Repeater®) series. Utilizing a positive-displacement principle, these tips feature an integrated piston that makes direct contact with the liquid, ensuring a complete and accurate dispense regardless of the fluid's physical properties. This design eliminates the air cushion found in standard pipettes, making the Combitips Plus the industry standard for handling volatile solvents, viscous oils, and radioactive or infectious samples. Manufactured from high-purity virgin polypropylene, these tips provide high-precision serial dispensing (up to 48 steps per filling) for increased laboratory throughput and reproducible results.

Technical Performance and Design

• Positive Displacement Technology: The internal piston wipes the cylinder walls clean during every dispense, ensuring 100% liquid recovery and preventing aerosol contamination of the pipette body.

• Multipette® Compatibility: Specifically designed for a perfect fit with the Eppendorf Multipette® 4780, Repeater® Plus, and Repeater® M4. These tips also fit most other industry-standard repeating pipettes.

• Precision Graduations: Features clear, easy-to-read volume markings that allow for rapid visual confirmation of the remaining liquid volume during long dispensing series.

• High Chemical Resistance: Constructed from medical-grade polypropylene, offering broad compatibility with common laboratory reagents, acids, and organic solvents.
