On the Multipette M4/Combitip System, volumes are dispensed using the positive displacement principle. The liquid is directly dispensed without an air cushion, ensuring the correct volume is always dispensed regardless of the densitiy, viscosity and volatility of the liquid. The Multipette M4 offer a unique volume range of 1 µL 10 mL, and its the only mechanical dispenser that dispenses the aspirated liquid up to 100 times without refilling the tip. The innovative step counter supports error-free working even after an interruption or distraction during the dispensing procedure. A fully emptied Combitip can be easily ejected with one hand using the operation lever without directly touching the tip. Features Repetitive dispensing modes decrease the number of movements by allowing the user to fill the tip once and dispense up to 100 times without a refill Automatic Combitip recognition eliminates timeconsuming volume calculations Wide dispensing range: 1 µL to 10 µL
