Power socket for 24V DC 1A
6. Preparing the pump for use
Plug the supplied PSU into your power socket and the low voltage plug into the socket on the
left side of the unit, switch it on by pressing the ‘ON’ button. The green LED on the side and
the display will illuminate indicating that the unit is operational.
The display will temporarily read ‘BOXER 9100’ and then the display will show the value it
has in it’s memory.
Note the direction of flow. The pump can be reversed in flow direction using the slide switch,
so that you can aspirate any unused reagent back into the reservoir.

IMPORTANT: CHOOSE THE RANGE THAT MATCHES THE ONE YOU ARE MOST
LIKELY TO USE IN YOUR APPLICATION.
7. Choosing the correct working range
There are 4 working ranges to choose from. These working ranges correspond to tube
diameters. The decimal point is shifted corresponding with the working range.
R1
ID Ø0.5mm for < 9ml
max display 9.000ml
R2
ID Ø1mm for < 25ml
max display 25.000ml*
R3
ID Ø2mm for < 90ml
max display 90.000ml
R4
ID Ø3mm for <190ml
max display 190.0ml
* The single µl digit can not be entered in R2 & R3
Working with low volume dispenses with large diameter tube will
reduce both precision and accuracy of dispenses.
Using the U/D keys scroll to the screen displaying “Range Enter?”
Press Enter.
Using the U/D keys choose the range corresponding to your tube
diameter and press Enter.
The display will show the last volume you worked with at that
particular range.
8. Gravimetric pump calibration procedure
Pump flow performance is subject of many factors among them the condition of the
peristaltic tube and the viscosity of the reagent. It is therefore important that you calibrate the
pump before it is commissioned using your reagent and at periodic intervals.
Carry out the calibration procedure using a volume nearest to the volume yiou are most likely
to dispense. You can choose any volume.
1.
Carry out 5 identical dispenses into a vessel and establish the
gravimetric volume dispensed in each operation.
2.
Calculate the mean dispensed volume.
3.
Using the U/D keys scroll to display saying “Calibrate Enter?”
4.
Press Enter
5.
The display shows “C” to indicate that you are in the
calibration mode and next to it the range which you calibrate
i.e. 1 to 4.
6.
Using the U/D keys correct the volume to your calculated
mean volume *
7.
Press Enter and the display shows the volume you intended to dispense. The unit is
now calibrated with a particular tube within your chosen working range.
* Volumes in R2 & R3 will increment by steps of 10µl
The unit will store the calibration you carried out for each individual range.
