Installation & Start Up
Installation of the LabTec™ System must be carried out only by trained personnel in accordance with
the relevant regulations and this operations manual.
Make sure that the technical specifications and input ratings of the LabTec™ are observed.
See “LabTec™ Specifications”.
The protection provided by this equipment may be impaired if the LabTec™ is used in a manner
inconsistent with this manual or for purposes not specified by the manufacturer.
Maintenance & Cleaning
The LabTec™ is practically maintenance free. The SciPres
®
sensors used with the system come
pre-calibrated from the factory and require no maintenance. The ™ peristaltic pump head should
periodically have tubing debris cleaned from it, but requires no lubrication.
Parker recommends a factory cleaning, testing and recalibration be done to your LabTec™ at least
once a year, to maintain the accuracy of the unit and reduce your downtime.
Contact Customer Service for an RGA or contact your Territory Manager. We can design a
preventative maintenance program specifically for your company.
To remove dust, dirt and stains, the outer surfaces of the LabTec™ may be wiped using a soft,
non-fluffing cloth moistened with water. If required, you may also use a mild detergent or 2-propanol.
The SciPres® sensors may be sanitized with 0.1 Molar NaOH, or 2-propanol. They may be autoclaved
up to twice, and may be gamma-irradiated.

3. At this point, you need to consider the parameters of the dispensing that you are going to do.
The following is a list of the various parameters available, and their defaults. We strongly suggest
that you use #24 Silicone tubing and these defaults initially, and then optimize your system after a
review of your results during the first few days of operation.
WGT FACTOR: Defines the weight ratio (multiplier) that is applied to the actual sample weight, as
determined by the scale, to arrive at the required diluent weight. WGT FACTOR = 9.00 is the default,
and will yield a 10-fold dilution. You may increase or decrease this to any ratio desired. Select a
WGT FACTOR = 99.00 if you want a 100-fold dilution.
SNIFFLE: The sniffle function consists of a brief pump reversal at the end of the dispensing cycle to
suck in the droplet that typically hangs at the end of the dispensing tip. When a filter is in use it will
relieve the pressure so it does not drip. Select SNIFFLE = 0.3. (The default is 0.0.)
SLOW FACTOR: Defines the diluent weight that is dispensed slowly at the end of the dispensing
cycle.The default SLOW FACTOR = 25.0 grams. This may be adjusted if necessary.
DIRECTION: Defines the rotation of the pump head. This parameter can be changed from clockwise
(CW) to counter clock-wise (CCW). (Default = CW)
PUMP RATE: Defines the relative pup speed (0% to 100%) with which the diluent is being
dispensed. The default PUMP RATE = 80%. This may be adjusted as needed. Higher speeds are
not recommended.
TIME DELAY: Not used in Weight Ratio Dispensing mode. Defines the time interval, in seconds,
between dispensing cycles. (Default = 00.01)
COUNT: Not used in Weight Ratio Dispensing mode. Defines how often the dispensing cycle will
be repeated. For example, when COUNT = 10, then the selected DISP. WEIGHT will be dispensed 10
times. (Default = 1)

Note: If you have more than one WGT FACTOR, store one WGT FACTOR in “ Edit 1”, e. g.
“9.00”, while a second WGT FACTOR is stored in “Edit 2”, e.g. “99.00”. Up to ten different
sets of parameters can be stored in “Edit 1” through “Edit 10”.
Note: The following may affect your accuracy, and should be considered:
1. Parker suggests you use #24 tubing, and move the portion inside the pump 3-4 inches toward
the discharge side of the pump periodically to avoid wearing it out. As the
tubing becomes
worn, your dilutions may take longer, and you may get debris in the diluent.
#35 tubing can cause target weight overruns, and is generally considered to be too large for
this application.
2. Sniffle Factor. This is a parameter that can be adjusted to minimize the drips that occur after
the dilution, thereby eliminating overruns. These procedures suggest an initial factor
of 0.3. If you are using a filter, this may need to be increased as the filter becomes plugged.
3. Slow Factor and Pump Rate. These parameters can be optimized further depending upon
your specific application. Increasing the Slow Factor will help if your scale response time
is long, and decreasing the Pump Rate will help if the default of 80% is causing too much
backsplash that can’t be eliminated in some other manner. The settings cited work best
with a Mettler Toledo model scale.

Hardware Setup:
1. Unpack all the components, visually identify and inspect for damage.
2. At the dispensing station, place the solution reservoir to the far left, and the LabTec™ to its
right. Position the
dispensing tip over the appropriately sized container.
3. Plug in and power up the LabTec™.
4. Cut approximately 10 feet of the #24 tubing and install the dispensing tip or filter on one end.
Mount that end of the tubing in the tubing clamp and position it so that it is just above
the container.
5. Route the tubing to the LabTec™, open the head by rotating the lever 180 degrees counter
clockwise, and place the tubing over the upper set of rollers. Confirm that the tubing is under
the centering springs and close the head by rotating the lever back to its original position.
6. Route the remaining tubing to the solution reservoir and attach it as appropriate.
Note: If you purchased the LabTec™ with your aliquot sizes preprogrammed by Parker the
calibrations have been done for you. If this is not the case, or you have performed a
Factory
Reset, you will need to edit the individual aliquots (Edit 1-10) as shown below.

17


Calibration:
1. The LabTec™ will come configured for the installed motor and pump head. This example will
assume a 600 rpm motor and a ™ 1082 head is installed. If you have a different head,
please refer to the manual or contact Parker for assistance. Each EDIT
(1 – 10) allows
a choice of tubing, and then accesses built-in master calibration curves.
In addition to adjustments to the motor speed and slow factor, fine tuning of the calibration
is accomplished by using the Re-Cal feature accessible directly from the “RE-CAL” button on
the front of the LabTec™.
2. The RE-CAL feature is accessible from the keypad of the LabTec™ using the “RE-CAL” button
located in the lower right-hand corner. To do this accurately, it is important that you have a
scale available to dispense the aliquot onto that has a readability of 0.1 gm or better.
A graduated cylinder may also be used. This feature is active when the following type of
display is shown:
3. After checking to be sure that the system is primed, Press the RUN key and dispense 10.00 mL
into the container on the scale. Record the weight, and do this for a minimum of 3 times, and
determine the average (AV) aliquot weight. For example, assume you obtained the following
values:
Trial 1 10.25 gm
Trial 2 10.30 gm
Trial 3 10.20 gm
AV = Average Value 10.25 gm
4. Press the “RE-CAL” key on the front panel of the LabTec™, and the following display
will appear:
DV = 10:00
Incr.
Decr.
AV = 10:00
Select
A B C
5. Only the AV parameter can be changed in this display, use the “A” and “B” keys to adjust the
value. In the above example, you would increase the AV value to 10.25. Press the “C” key to
Select and the stored calibration curve will be updated. You may wish to repeat the RE-CAL as
necessary for improved dispensing accuracy.
6. This procedure is performed after all of the EDIT parameters explained below have been
entered into the LabTec™ for that particular aliquot.
VOLUME SET: 10:00 mL
Press RUN when Ready

18


Program Editing and Execution
At this point, you need to consider the parameters of the dispensing that you are going to do. The
following is a list of the various parameters available, and their defaults. Adjust these parameters
based on the volume that you are dispensing.
DISPENSEVOLUME:Defines the volume to be dispensed in milliliters. (The default volume is 10.0
mL).
PUMPTUBING: This choice exists if a peristaltic head has been installed. Choices are 13, 14, 16,
25, 17, 18, (thin-walled, 1081 Head) 15, 24, 35 (thick-walled, 1082 Head). The built in master
calibration for that tubing is then utilized. (Default = 13)
SNIFFLE: The sniffle function consists of a brief pump reversal at the end of the dispensing cycle
to suck in the droplet that typically hangs at the end of the dispensing tip. It also will relieve the
pressure on a filter if you are using one so that it does not drip. (The default Sniffle = 0.3, please
start at 0.0 if not using a filter.)
SLOWFACTOR:Defines the solution volume that is dispensed slowly at the end of the dispensing
cycle. This should be set between 1-10 mL depending the volume being dispensed and the tubing
size to avoid overshooting the target volume. For example, if you’re using #15 tubing, and the target
volume is 100 mL, a slow factor of 1 or 2 mL will work fine. The default Slow Factor = 1.00 mL. This
may be adjusted as necessary.
DIRECTION:Defines the rotation of the pump head, this parameter can be changed from clockwise
(CW) to counter clock-wise (CCW). (Default = CW).
PUMPRATE:Defines the relative pump speed (0% to 100%) with which the solution is being
dispensed. The default Pump Rate = 100%. This may be adjusted as needed, slower pump rates
may be desirable to increase precision and minimize back splashing.
TIMEDELAY:Defines the time interval, in seconds, between dispensing cycles. (Default = 1.0).
COUNT:Defines how often the dispensing cycle will be repeated. For example, when COUNT = 10,
then the selected Dispense Volume will be dispensed 10 times. (Default = 1).
1. For this example, the tubing will be #24, and a dispense volume of 100.00 mL. From the Mode
Select screen, use “A” or “B” to go up or down to the “Volume” mode, and Press “C” to select it.
The Volume mode will give you the following display.

6. All other parameters will be left at their defaults. Press the exit key to return to the “Volume”
screen and Press the “Exec” key, this will show the Exec program that matches the Edit
program you were just in. Continuing with this example, press “C” to select, and the LabTec™
will show the following display:
7. Press the “RUN” key, and the LabTec™ will dispense 100.00 mL, and show the following screen:
DV=100.00 mL P1=0.0
CV= 100 mL SC=001
Where DV=Dispensed Volume, CV=Cumulative Volume, SC=Sample Count # for the volume
dispensed, will increment by one for each occurrence, and P1=Back Pressure (will be 0.0 if
no pressure sensor is in use). The display will then alternate between this screen and the one
before it.
8. At this time it is appropriate to use the RE-CAL procedure mentioned in the earlier Calibration
section to fine tune the process. Once satisfied with the results, you can continue pressing the
run key until you have finished the needed number of aliquots.

Note: The following may affect your accuracy, and should be considered:
1. Parker suggests you use #15 or 24 tubing, and move the portion inside the pump 3-4
inches toward the discharge side of the pump periodically to avoid excessive
wear. As the
tubing becomes worn, you will want to run the RE-CAL feature again.
#35 tubing will allow you to pump at higher flow rates, but a larger slow factor should
be implemented.
2. Sniffle Factor. This is a parameter that can be adjusted to minimize the drips that occur
after dispensing, thereby eliminating overruns. These procedures suggest an initial factor
of 0.0. If you are using a filter, this may need to be increased as the filter becomes plugged.
3. Slow Factor and Pump Rate. These parameters can be optimized further depending upon
your specific application. The Slow Factor should be set to 1 or 2 mL for most tubing, and
up to as much as 5 mL if you are using large diameter tubing. Decreasing the Pump Rate
will help if the default of 100% is causing too much backsplash that can’t be eliminated in
some other manner, or if the dispense volume is small.
