Midi Plus Pipette Controller
Easy and Ergonomic Pipetting ofLarge Volumes From Bottles or Tubes
Introduction
Midi Plus is a light-weight electronic
pipette controller, which allows easy liquid
aspiration from bottles and large tubes. Its
ergonomic design helps to minimize armand hand raises that are often required
while using serological or volumetricpipettes. This eases the workload in long
periods of pipetting and protects the userfrom Repetitive Strain Injury (RSI). Midi Pluscan be used with commonly used glass orplastic pipettes in the 1 to 100 mL volume
range, and also with 5 mL and 10 mL
Sartorius Optifit Tips, adapters available
separately.

Description
Midi Plus is developed for easy and safe large-volume
dispensing. It provides an ergonomic alternative to thesimple pipette filler with squeezable bulb, which requires
extensive finger force when aspirating and dispensing
liquids. The electronic operation of Midi Plus reduces thefinger force needed, and the stepless speed control
improves the control of the liquid flow for better accuracy.
Dispensing by the force of gravity is possible by applyinggentle finger pressure on the operating button. Pipetting
accuracy depends on the user’s ability to set the menis­cus of the liquid at the graduation marks on a serologicalpipette. The improved battery enables quick charging
and long battery lifetime. When the battery is low, it canbe charged while working. When fully charged, the cord
can be unplugged from the device, allowing safe andconvenient cordless pipetting.

Features Ergonomic handle design with electronic operating
buttons for reduced finger force
 Stepless speed control for accurate dispensing Possibility of dispensing with the force of gravity for slow,
drop-by-drop dispensing (e.g., into culture media dish so
as not to break the fine surface of the medium) Fold-out stand saves bench space when Midi Plus is not
in use and keeps the pipette detached from the tablesurface to avoid contamination
 Wide compatibility with glass or plastic pipettes, also
compatible with Sartorius 5 mL Optifit Tips and 10 mL
extra-long Optifit Tips (adapter sets for 5 mL and 10 mL
tips available separately) Hydrophobic 0.45 μm and pre-sterilized 0.2 μm filters
prevent over-aspiration and contaminationof the device
 Direct charging cable enables operation while charging
 Low battery indicator

Applications
 Cell culture Liquid preparation in large volumes

Intended Use For large volume pipetting from bottles or large tubes
