Due to special polymers and an extremely smooth inside surface, the ExpellPlus™ tips virtually eliminate sample retention, and reduce the binding of DNA, RNA and Proteins to a very minimum. Especially useful when working with fluorescent dyes and conjugates, the ExpellPlus tips limit non-specific binding and quenching. Tests show that the ExpellPlus tips deliver volumes within 0.1 % of the set volume, versus 0.5-0.7% for standard tips.
Perfectly matched with the full line of Capp and Evolution pipettes, they provide a superior pipetting performance which means saving valuable samples and improved pipetting accuracy and precision. Expell and ExpellPlus tips can also be used with all other major pipettes on the market.
