The Eppendorf Repeater Pipette makes repetitive pipetting faster and more accurate than ever. You can pipet up to 48 times at one second intervals without refilling. Just set the selection dial and your choice of volume is locked in place. It is ideal for use with aggressive or viscous liquid, since liquids contact only the tip, never the instrument itself. The disposable combitip eliminates cleaning, contamination, and carryover, but can be refilled and reused as long as the same liquid is being pipetted.
