The Eppendorf InjectMan
for use in microinjection.
Its optimum functionality and user-friendliness make the InjectMan® NI 2 the ideal solution for
easy injection. This is illustrated particularly by the large number of injected cells.
The Eppendorf InjectMan® NI 2 micromanipulator combines the classic benefits of a
mechanical system (direct feeling for tool movements) with the advantages of a precise
motorised system.
The direct and sturdy adapter between the module unit and the microscope tripod (optionally
positioned at the left or right) and the separate control board prevent oscillation and vibration.
Connection to the FemtoJet®, FemtoJet® express or Transjector 5246 also permits
semi-automated injections. The injection motion and pressure are activated simultaneously at
the press of a button.
The highly resource-conserving way in which the microcapillaries are injected axially at any
desired angle into the cell, and also extracted axially, considerably increases the effectiveness
and broadens the range of application of microinjection.
No manual wobble of the capillary can damage the cell. The microelectronics and the software
help to conserve the cells to the maximum extent.
The clearly laid out keypad with the additional display also help to avoid operator errors and so
protect the preparation and the tool.
The unit can be attached to any commonly used inverted microscopes by way of an appropriate
adapter. The capillary can be aligned at any angle and in any direction.
Defined working planes and limits largely eliminate the possibility of damage to the capillaries.
An integral CLEAN/HOME function greatly eases the handling and changing of capillaries.
Simple, self-explanatory user control also permits inexperienced users to begin performing
injections into adherent cells quickly and successfully. Additional functions are available for the
more experienced user.

2 Intended use and safety precautions
The InjectMan NI 2 enables an electronically controlled axial injection movement. It is designed
for controlled, gentle, semi-automatic microinjection in (adherent) cells and small organisms. By
coupling with an external pressure source/external pressure sensor (e.g., FemtoJet (express) or
Transjector 5246), the injection movement and injection pressure are monitored, and simultaneously activated at the push of a button. Microelectronics and software control the cell-preserving execution of the microinjection process. The cell wall is minimally perforated, thus
avoiding cell lysis (via the potential introduction of excess volumes of liquid). In the optimal scenario, inspecting the work area and injection limits reduces damage to the capillaries.
The InjectMan NI 2 is only intended for use in research labs. It may only be operated by qualified
lab personnel.
It is essential to observe the following safety precautions!
•
The device must be commissioned and subsequently used in compliance with the instructions set out in this Manual, in order to protect the user and prevent damage to the device!
•
The device may only be used for the purpose for which it is intended!
•
The device is to be used solely for micromanipulation in accordance with the appropriate
legislative requirements!
•
Do not operate the device if there is visible damage to the device itself and/or to its
packaging.
•
Before starting up the device, please compare your power supply with the voltage
requirements on the identification plate!
•
Take care when transporting the control board!
Do
not
transport the device by carry the joystick!
•
When installing and dismantling, make sure the weight of the motor module (1.4 kg) can be
safely carried! Otherwise injury may be caused, or the device may be damaged!
•
A weight of max. 100 g may be applied to the motor module.
•
The motor modules must not be moved against a mechanical obstacle, as this may damage
the drive units.
•
Before transporting the micromanipulator, dismantle the module unit and, if possible,
transport it in its original box. The delivered transport guards are to be mounted according
to the red supplement sheet.
•
•
•
Important!
The mains plug must not be plugged into the socket outlet until all connections
between the control console, power supply unit and motor module have been
made.
Caution – risk of trapping/crushing!
Do not reach into areas of the motor modules in which your hand may become
trapped (the gap between the guide and the module or between the module
and any obstacles), and do not insert any other objects into such gaps!
Caution when mounting tools!
Mounting must not be performed with pressure. Glass capillaries can be
damaged during mounting if they are not handled carefully. Wear eye
protection to prevent the risk of injury from glass splinters!

Disposal
In case the product is to be disposed of, the relevant legal regulations are to be observed.
Information on the disposal of electrical and electronic devices in the European
•
Community
The disposal of electrical devices is regulated within the European Community by national
regulations based on EU Directive 2002/96/EC on waste electrical and electronic equipment
(WEEE).
According to these regulations, any devices supplied after 13.08.05 in the business-tobusiness sphere, to which this product is assigned, may no longer be disposed of in
municipal or domestic waste. They are marked with the following symbol to indicate this.
Caution when mounting tools!
When the tool is mounted, the motors are swung out forwards and the
capillaries face the front. Handle with care!
Caution!
If the work is not carried out properly, for example if glass capillaries contact
a surface, they may smash and flying splinters may endanger eyes. You should
therefore always protect your eyes, such as by wearing goggles!
Never point capillaries at persons!
Capillaries can suddenly be loosened from their capillary grips under high
pressure and become a missile.
As disposal regulations within the EU may vary from country to country, please
contact your supplier if necessary.

The module unit can be mounted at the left or right on any commonly used microscopes by way
of an adapter.
The module unit comprises the motor unit for horizontal movement (X, Y axis,
X/Y module) and the axial motor unit (A axis). The injection angle is adjusted manually using the
angle guide. By means of the angle setting and appropriate mounting, injection angles between
60° and 30° are possible.
Vertical movements (Z movements) are executed by the interaction between the A and X axes.

The A module is attached by bolting on the angle guide.
Depending on the mounting point of the angle guide, injection angles between 60° and 30° can
be set.
For the sake of clarity, the A module is not shown.

Example:
The angle guide is attached to the X/Y module in the
centre hole, corresponding to 45°. The A module can
be adjusted to between 55° and 35° (45°±10°) by

changes each time to 50° to 30°.
By moving the mounting point downwards, angles of
up to 60° can be set. This requires sufficient space to
be available on the microscope.
The angle guide is already bolted to the A module.
The spindle may need to be turned until the desired
mounting point (arrow, e.g. here centre hole) is
accessible.
Note
face of the A module must be slackened prior to
adjusting the angle and must then be re-tightened in
order to ensure reliable operation.

Mounting the angle guide at the centre hole and
adjusting the A module to 0° corresponds to an angle
of 45°.
To perform the adjustment, the lines on the angle
guide are moved to match the outer edge of the A
module.
Example – 35°: The angle guide is attached by the
centre hole, the bottom edge of the A module is set to
the lower 10° marking.
Note
: The mechanically set angle must be entered
subsequently in the Install menu! Otherwise Z axis
movements cannot be executed correctly! See
section 5.4.2.6.
Note

the A module must be slackened prior to adjusting the
angle and must then be re-tightened in order to
ensure reliable operation.

Installation
To open the hinged bracket beyond its normal
opening angle between 0° and 45° for mounting
purposes, push the pin on the hinge side up. The
slider is purposely hard to move. The unit is usually
only mounted once. The pin can be moved with the 4
mm Allen key.
