The Repeater M4 pipette by Eppendorf North America, Hauppauge, NY, minimizes the time and effort required to maintain precision during repeat dispensing tasks. It uses the positive displacement principle to dispense liquids precisely and accurately.

Because air cushions are not used, the correct volume is dispensed regardless of the density, viscosity, or volatility of the liquid. Using the company’s Combitips, the pipette dispenses aspirated liquid from 1 µL to 10 mL up to 100 times without refill. It features a step counter, which eliminates errors even during an interruption or distraction at the time of the dispensing procedure. In addition, the central Combitip ejector supports one-handed operation for contact-free tip ejection that avoids any risk of contamination.

The Repeater M4 recently received an award as best new general lab product of 2014 in the SelectScience scientists’ choice award program.
