3 PIPETTE OPERATIONS
The Finnpipette BioControl has four different operating modes: RESET, PIPETTE,
OFF.
RESET MODE
The pipette automatically switches to reset mode (on-screen text
CALIBRATE) whenever the snaplock attaching the tip cone
module has been released or the pipette has been recharged from
empty. To activate the pipette, close the snaplock, choose the
appropriate module (on the display) and press the set key. Press
the dual-stop trigger to the second stop. Release the trigger, and
the pipette is ready for use (Fig.6).
PIPETTE MODE
Pipette is the normal operating mode. Forward and reverse pipetting are possible without programming.
STEPPER MODE
In stepper mode, the volume selected is dispensed repeatedly until the maximum capacity of the tip cone
module has been delivered.
POWER OFF MODE
The pipette switches to
POWER OFF
movement reactivates the pipette, switching it back on. Volume and mode settings remain as before.
CHANGING THE TIP CONE MODULE
To change the tip cone module, first open the snaplock (about 45 degrees), and then pull out the module.
To attach the module to the pipette, insert the module in the pipette and close the snaplock. This activates
the
RESET
mode. (To activate the pipette, close the snaplock) Next, choose the appropriate module
(channel number and max. volume will be blinking on screen). Accept the previous module by pressing
the
SET
key or choose another module by pressing the + or - keys. Confirm your selection with the
key. Then press the dual stop trigger to the second stop, so the piston mechanism inside the handle
descends to its lowest position. Release the trigger, and the pipette is ready for use (Fig.6).
TIP EJECTION
To eliminate the risk of cross-contamination, the Finnpipette BioControl has a specially designed tip
ejector lever. Eject tips by pressing down the lever (Fig. 3). If you are left-handed, just rotate the tip ejector
lever to the opposite side of the handle (Fig. 4) and press the lever with your left thumb.
SELECTING PIPETTING MODES

the normal aspirate and dispense technique, can be used with or without blow-out. In stepper mode, the
pipette repeatedly aspirates and dispenses the selected volume.
To change modes, press the
screen. To confirm your choice, press SET. If you do not press
return to the previous setting. You cannot change modes when the trigger is pressed.
