The Eppendorf Repeater® M4 and Combitips advanced® System uses the positive displacement principal to precisely and accurately dispense virtually any liquid. The liquid is directly dispensed without an air cushion, ensuring the correct volume is dispensed regardless of the density, viscosity and volatility of the liquid. The Repeater M4 has a unique volume range of 1 µL - 10 mL, and is the only mechanical dispenser that dispenses up to 100 times without refilling the tip. The new and innovative step counter supports error-free working even after an interruption or distraction during the dispensing procedure. Fully emptied Combitips® can be easily ejected with one hand using the operation lever without directly touching the tip.
