Scilogex Unoverse Peristaltic Pump Dispense 9100 - Manual (Page 4)

1. The peristaltic tube
The peristaltic tube is made from
Santoprene and the connectors are
Nylon (PA). Please make sure the
reagents you intend to use are
compatible with these materials
(See Chart).
1. A. Clamping the peristaltic tube
The pump controller is delivered with
a IDØ2mm Santoprene tube. In
order to reduce deformation caused
by clamping the pressure lever
(1) is
supplied in the open position .
Before use ensure you turn the lever
down to the fully clamped position
1.B. Releasing the peristaltic tube
when you have finished
Whenever the pump is not in use for
long periods of time it is important to
release the pressure off the tube.
This will reduce the possibility of the
tube’s permanent deformation and
ensure that accuracy/precision is
maximised.
Release the pressure by lifting the
pressure lever
1.C. Replacing the tube
For work in small volumes use the
IDØ1.0mm tube which is available
as an accessory.
Lift the lever and remove the pump’s
cover. Pull out both tube holders
and remove from the cover. Replace
with a new tube.

(1) The pressure lever moves the pump cover towards the
rollers and thus clamps the tube between the cover and
the rollers.

5. Adjusting the dispense volume
Press keys ‘VOLUME+UP’ or ‘VOLUME+DOWN’ to enter the volume nearest to your desired
volume.
Make sure the tubes terminate in a receiving vessel and press ‘START’ to begin dispensing.
For priming or to dispense more than the set volume , hold down the START key.
6. Interval Dispense
You can set the unit to dispense the desired volume for a number of times in predefined
intervals. This feature is useful in repeatable operations either in manual mode or when the
dispense head is held by a robotic arm.
To set repeat dispensing:
1. Interval time setting: Select between intervals of 1-99 sec or 10
to 990 seconds. Press and hold down the ’INTERVAL’ key and
press ’DOWN’ key to select 1 to 99 seconds or ’UP’ key for 10
to 990 seconds. If you are not sure in which mode the
instrument is, enter the desired mode prior to any further
programming.
2. Press ‘INTERVALS’ - the display flashes the first two digits to
the left. These digits denote the time in seconds between the
dispense operations.
3. Using the ‘UP’ & ‘DOWN’ keys enter the number of seconds or
10Xsec you wish to have between the dispenses— from 1
second to 99 seconds.
4. Press ‘INTERVALS’ and the second set of digits will flash. This
digits denote the number of dispenses you wish to have—from 1
to 98 dispenses.
5. Using the ‘UP’ & ‘DOWN’ keys enter the number of dispense
events—between 1 and 98.
6. Press ‘INTERVALS’ and the display will show the volume. The
colon between the two sets of digits flashes to indicate that an
interval dispense mode has been entered into the unit. You can
now adjust the volume as indicated in the previous paragraph.
7. Press ‘START’ and the controller will dispense the set volume in
the interval mode which you have entered into the unit.
8. Press ‘STOP’ + ’INTERVALS’ button to stop the intervals mode.
The flashing colon will disappear from the display.
9. To change any of the interval parameters simply press the
‘INTERVALS’ key again and enter new parameters
10. Panic stop: You can press the ‘STOP’ button at any point
throughout the dispense mode to terminate the automated
dispense operation.
11. Note that in the dispense process the display shows the
seconds left before next dispense and the running event
number.
12. Continuous dispense: To dispense your chosen volume
continuously at the interval time you selected, enter ‘99’ as the
number of repeats. This will prompt the unit to dispense
continuously until the STOP button is pressed. Remember to
check the tubing condition from time to time.
