The Multipette M4 mechanical multi-dispenser pipette allows you to aspirate liquid once and dispense up to 100 times, making it the ideal precision instrument for long, repetitive pipetting tasks, such as tube or plate filling, and aliquoting reagents. Liquid is aspirated and dispensed by positive displacement, which means there is no air cushion that may be affected by liquid sample properties. This ensures that the correct volume is always dispensed - regardless of the density, viscosity and volatility of the liquid.

The Combitips^® advanced positive displacement dispenser tips are automatically recognized - eliminating time consuming volume calculations - and are hermetically sealed to provide a high level of user, instrument and sample safety. Ideal for handling infectious, toxic or radioactive liquids.

Eppendorf pioneered the Multipette/Combitips multi-dispenser system in 1978 and improved it several times since. It was the very first pipetting system allowing users to fill the tip once and dispense multiple times. The concept remains a driver for efficient liquid handling and a staple in many labs working with plates or series of tubes.
