Quick Start Guide
Midi Plus Electronic Pipetting Controller
Getting Started
1. Midi Plus is delivered with the battery inserted. The battery poles are covered by a
plastic protective film. Before first use, remove the plastic film by pulling it gently from
below the battery cover.
2. Charge Midi Plus for at least 4 hours before first use.
- To charge with AC-adaptor: connect Midi Plus to the charger cable and plug the
charger into the mains power outlet.
3. The battery status is indicated by a LED. When the battery is fully charged the LED
emits a green light, and the Midi Plus is ready for use.
Midi Plus is equipped with an adapter set (nose-cone and silicone adapter) that fits all
commonly used serological or volumetric pipettes.

4. Aspiration:
- Immerse the pipette into the liquid
- Press the aspirating button until the pipette is filled just above the desired volume
- Lift the pipette from the liquid
- Press the dispensing button to slowly dispense the liquid until the level is exactly at the
desired volume
5. Dispensing:
- Place the pipette against the receiving vessel wall
- Press the dispensing button until the pipette is empty
- To activate the blow-out, press the dispensing button completely
NOTE! Press the dispensing button gently to let the liquid flow out by the force of gravity. Fine-tune the
speed by adjusting finger pressure while dispensing.
NOTE! To ease the aspiration of certain liquids, such as volatile or viscous ones, increase the speed, especially
when using a large volumetric pipette.

Fold-out stand
Other Recommendations
1. When not in use, Midi Plus should always be placed
on a table to rest on the fold-out stand.
2. The LED indicator starts to blink when the battery
charge level is low: connect the Midi Plus to the
power supply.
- Pipetting is possible while connected to the
AC-adaptor.
3. Midi Plus can be used with Sartorius Optifit 5 ml and
10 ml tips. Adapters for the 5 ml and 10 ml Optifit
