Aspirate liquid once and dispense up to 100 times without tip refill
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.

Advanced interface and sensor control for easy operation

Step counter
• Displays the number of executed dispensing steps

Volume selection dial
• 20 different volume settings for every size of Combitips advanced

Motion sensor
Even if a Combitips advanced dispenser tip is left attached, the Multipette M4 switches off when not in use to save power. When moved again, it switches back on automatically, while still “remembering” the number of executed dispensing steps for increased efficiency.

Combitips advanced attachment sensor
• Automatic Combitips advanced tip recognition and volume display
• Ensures a secure connection between Combitips advanced and Multipette M4

Make long, repetitive pipetting tasks more comfortable

With its easy-to-reach and easily adjustable volume selection dial, the Multipette M4 makes repetitive pipetting tasks manageable. A hand rest supports a relaxed, ergonomic hand position and ease-of-use, ensuring the Multipette M4 provides a greater level of comfort over the day.

The ergonomically shaped operating lever both fills and dispenses the liquid, and also ejects the Combitips advanced dispenser tips, with one-handed operation.

Convenient storage options for your multi-dispenser & pipettes

Our Multipette M4 pipette holders for wall mounting or the Eppendorf Pipette Holder System can be affixed to virtually any surface or integrated with either our charging or non-charging manual pipette carousel stands. Alternatively, one Multipette M4 multi-dispenser can be stored in the Pipette Stand 2 by Eppendorf.

Applications:

• Repetitive dispensing of volumes in long series such as tube or plate filling, aliquoting reagents and kit usage
• Safe dispensing of toxic, radioactive and other hazardous liquids
• Precise and accurate dispensing of viscous solutions (e.g. glycerol) or liquids with high vapor pressure (e.g. ethanol)
