This manual is subject to a permanent quality control. The current version of the
manual can always be acquired from the download section of our homepage
www.kruss.de.
SPAC SPAC S PAC SPA C
The system is characterized by its high degree of flexibility. All the components
– movement axes, video system, dosing unit, environmental chambers – can be
easily exchanged or extended. All intermediate stages are possible from fully
manual operation up to PC-control of all the components.
Possible uses of the DSA100
The DSA100 measuring system – depending on the hardware and software
supplied – opens up the following possibilities:
Contact angle measurements on drops of liquid in a gaseous or liquid phase
Measurement of the surface tension of a pendant drop in a liquid or gaseous
phase
Measuring of advancing and receding drops
Evaluation of a digitized drop image by various methods
Calculation of the surface energy of a solid by various methods
Automatic control of the instrument and data recording by user-defined test
methods
Measurements at low and high temperatures
Page 11
Introduction page 9
Integrated and extendable databases with substance data on liquids that can be
directly linked to the measuring data
Comfortable data management and documentation
Extendable at any time with components such as environmental chambers,
automatic axes, software-controlled optics or multiple dosing units with up to 8
syringes
Page 12
page 10 DSA100 overview
3 DSA100 overview
In order to measure the contact angle with the DSA100 a drop is placed on a
sample located on a moveable sample table. The drop is illuminated from one side
and a camera at the opposite side records an image of the drop.
The drop image is transferred to a computer equipped with a video-digitizer board
(frame grabber) and shown on the monitor. The DSA software contains timeproven tools for analysing the drop image with whose help it is possible to
calculate the contact angle, surface energies and surface tensions.
In principle the DSA100 consists of three components:
The sample table with up to three mobile axes or a rotating wafer table
The video system with camera, optical system, prism, light source and aperture
A manual or software-controlled dosing unit, single or multiple
Dosing unit

6.2 Assembling and adjusting the prism
The prism is a sensitive component and must therefore be built in after delivery.
Do not touch the prism glass with your fingers or sharp or pointed objects.
Remove the protective cap from the objective.
Insert the prism in the opening and push it upward until it clicks into position.
The prism can be tilted in order to change the viewing angle of the drop. The
advantage of this arrangement is that the position of the drop image does not
alter and the image itself is not distorted.
The tilting angle is regulated by using the rotary knob beside the prism. When
the instrument is switched on the scale on the left-hand side of the housing
shows the set tilt angle.
The default settings are 0° for pendant drops and +2° for sessile drops (contact
angle measurements).

7.2 Mounting a spacer
When the DSA100 is delivered the required spacers are usually already
mounted.
7.2.1 Threads for mounting spacers and axes
Each of the spacers has three threaded holes for screwing onto a different spacer
(S) and four threaded holes at the corners for screwing an axis (A) onto the spacer:
Mount the spacer on top of the already mounted spacer using the three
hexagon socket screws provided.
In rare cases the spacer must be mounted on the base plate of the DSA100.
7.2.2 Replacing an axis with a spacer
If an axis must be removed or replaced by a spacer, proceed as follows:
1. Move the installed x or y axis out of the center to that the fixing screws are
released.
With software-controlled axes: please consult the software manual to see
how the axes are moved.
2. Remove all available cable connections from the axes.

7.3 Mounting axes
Safety note
The axes are fixed at four edges with one screw each. Tighten up the screws in
rotating order to achieve uniform stress and avoid tilting.
Fixing strips
Each axis is either screwed onto a spacer or onto another axis. To mount an axis,
fixing strips are required as follows:
Two strips without threads for attaching an axis to a spacer
Two strips with threads for attaching a z-axis to an x-axis or y-axis
Page 36
page 34 Mounting axes
!
Four strips, two with and two without threads, for attaching a y-axis to an x-axis

If only the z-axis is present then no fixing strip is required; the axis is screwed
directly onto the spacer.
Not always are all strips used which were delivered. Keep the unneeded strips
save. They may be required for the occasion of conversions.
7.3.1 Mounting an x- or y-axis on a spacer
1. Place the axis on the built-in spacer and hold it firmly. The axis should be
positioned so that the spacer is located below the centre of the range of
movement of the axis.
2. Place the non-threaded fixing strips on the spacer so that the cramping edges
fit inside the ridges of the axis.

7.5 Mounting a rotating table
A rotating sample table cannot be used together with the x-axis, but only as an
alternative to it. If an x-axis is already attached then it must be removed before
mounting the rotating sample table.
It is recommended to carry out the mounting steps with two persons.
7.5.1 Removing the x-axis (if present)
For safety reasons first remove the prism and keep it in a safe place when
carrying out the assembly work.
1. If software-controlled axes are installed then switch on the computer and start
the DSA software.

10.1 Initialising the syringe drives
CAUTION
Risk from escaping liquids (toxic, highly flammable or corrosive)
If syringes are already inserted and filled, liquid which escapes during the
initialization can lead to a risk depending on the hazard class of the liquid
Empty the syringes and lead the liquid into a waste container before starting
the initialization.
For DSA1 only: In order that all available syringes can be controlled with the
DSA1 software, an initialisation file matching the dosing unit must be copied
into the installation folder of the DSA1 software ( Appendix

3. Put a PTFE gasket onto the tip of the first syringe.
Screw the syringe with the gasket a few turns into the syringe socket of the first
valve in order to insert the gasket.
Remove the syringe.
4. Loosen the knurled screw at the piston fixture.
The screw must be loosened far enough to fit the knob of the piston into
the clamp of the piston fixture.
5. Fill a storage vessel with the test liquid intended for the first liquid.
The amber glass bottle is intended for diiodomethane or other light-
sensitive liquids.
6. Fill the syringe with the test liquid without allowing any air to enter the syringe.

7. Lead the tube coming from underneath the syringe drive from the top though
the opening in the silicon seal of one of the red caps.
SPAC SPAC S PAC SPA C
Use clean gloves to carry out this step. When the tube end gets
contaminated from the outside it can in turn contaminate the test liquid.
Page 67
Multi-dosing unit DS3226-3228 page 65
8. Slowly press the syringe piston upward manually in order to press the test liquid
through the refill tube. Absorb escaping liquid.
KRÜSS recommends: Press the piston upward to a point just below the
piston holder. Thus, only a small amount of liquid will be pressed into the
storage vessel when inserting the piston.
As an alternative, the piston holder can be put into position with the help of
the dosing function of the software ( DSA1/DSA3/DSA4 manual).
9. Screw the cap onto the filled storage vessel. Let the tube dip into the liquid so
that no air can be enclosed. Push the tube far enough through the opening for
it to reach the bottom of the bottle.
10. Lead the knob of the piston into the piston holder. In order to do that, correct
the piston position until the knob fits into the fixture.
Fasten the knurled screw.
11. Puncture the silicone seal with one of the needles supplied. Leave the needle in
the hole.

2. Unscrew the two hexagonal socket screws underneath the sample table support
using an Allen wrench.
Sample table adapter
Remove the sample table adapter.
3. Place the chamber on the sample table. Screw the chamber securely to the
sample table using the screws which were removed in Step 2.
11.5 Connectors and connections
11.5.1 Connecting the thermostat
Both environmental chambers are connected to a thermostat. In most cases,
water is used as the thermostat liquid.
Do not use silicone oil because it attacks the seals and tubes. Vegetable oils
and ethylene glycol on the other hand are suitable liquids.
Page 73
Environmental chambers TC30 and TC40 page 71
Connect the Quick-Lock connections at the ends of the hoses to a flow-through
thermostat.
11.5.2 Condensation protection
At a high relative humidity condensation could form on the viewing and measuring
window with measurements below room temperature. In order to prevent this, the
divided tube connectors are used to direct a stream of air through the chamber
and past the windows.
Measurements without heat conducting hood
Connect the tube attached to the top connectors to a compressed gas supply
(approx. 500 mbar).
Measurements with heat conducting hood:
Connect the tube attached to the top and bottom connectors to a compressed
gas supply (approx. 500 mbar).
Page 74
page 72 Environmental chambers TC30 and TC40
!
11.5.3 External temperature sensor
The temperature above the sample can be measured with the help of an external
temperature sensor.
If the heat conducting hood is used then this must be placed in position before
the temperature sensor is inserted.
With the sample drawer closed, slide the sensor into the guide on the top of the
chamber.
Make sure that the inserted samples do not come into contact with the
sensor; if necessary pull the sensor out slightly.
Connect the temperature sensor to the connector on the DSA100 provided for
the purpose ( Chapter 5.8).
11.5.4 Inert gas connector

11.7 Additional components
A heat conducting hood and a base plate attachment for flat samples are included
as additional components.
The heat conducting hood and the base plate attachment cannot be used at the
same time.
11.7.1 Base plate attachment for flat samples
In order to capture flat samples in the video image, a base plate attachment can be
placed on the base plate.
11.7.2 Heat conducting hood
Using the optional heat conducting hood ensures a better transportation of
heat in the interior of the chamber and thus reduces temperature variations.
When the heat conducting hood is used, the target temperature will be
achieved more slowly.
1. Pull out the sample drawer. Remove the two holding clamps if necessary.
Withdraw the temperature sensor if fitted.
2. Position the sample on the plate.
3. Fit the hood so that the slot is at the rear.
4. Push the drawer back into the chamber.
5. Fit the temperature sensor if necessary ( Chapter 11.5.3).

11.8 TC40 only: Setting and reading off the measuring temperature
11.8.1 Safety instructions
WARNING
Risk of burns from chamber heating up unexpectedly
If too high a temperature has previously been set then burns could occur after
switching on the control unit.
After use reset the temperature at the control unit to room temperature.
Observe which set temperature appears on the display after switch-on and, if
necessary, set a lower value.
The Peltier element could be damaged if it is heated up without countercooling.
Always switch the thermostat on before the control unit and set a suitable
temperature.
Make sure that the flow is not impeded by kinks in the tube.
11.8.2 The temperature controller
The required temperature is set by using the CONTROLLER element on the control
unit of the TC40.
Immediately after the mains switch is switched on, the control unit initializes itself
and is ready for use after about 3 seconds.
Temperature display
The top line indicates the current temperature of the heating elements.
The set temperature is shown in the lower line of the display.
The temperature measured by the external temperature sensor is not displayed.
To display this, please refer to the DSA software manual.
Page 81
Environmental chambers TC30 and TC40 page 79
!
Setting the desired temperature
The desired temperature is set by using the two arrow keys ( = temperature
increase;
Pressing the key briefly changes the temperature in one-tenth of a degree
steps.
Fast adjustment is carried out by pressing the key longer.
No functions are assigned to the two keys and .
= temperature decrease).
11.8.3 Setting the thermostat
With the TC40 the thermostat is used to mediate between room temperature and
target temperature.
The given temperature limits of 160°C or -30°C can only be achieved when the
Peltier element is supported by the thermostat.
As a rule of thumb the temperature difference between the measuring
temperature and the thermostat liquid should not exceed 30°C when cooling
down and 70°C when heating up. However, greater temperature differences can
be used in the temperature range between –10 and 120°C.
The following table assumes that water is used as the thermostat liquid:
Measuring temperature range Recommended thermostat setting
-30°C to 10°C 2°C
-10°C to 120°C 20°C
50°C to 160°C 85°C

!
12 Humidity chamber HC10
The HC10 Humidity Chamber is used together with a TC30 or TC40 environmental
chamber.
12.1 Temperature range and method of temperature control
The humidity chamber HC10 can be used in a temperature range between 5 and
90°C.
It is possible to operate the TC40 environmental chamber alone with the
Humidity Chamber HC10 connected.
The maximum permissible temperature is reduced to 120°C when an HC10
chamber is connected.
If a TC40 is used then the Peltier element is not used for temperature control.
Instead the temperature of both environmental chambers is controlled by an
external thermostat.
12.2 Notes for use
In order to prevent condensation at the windows the humidity should be set
after the required measuring temperature has been reached.
After using, the environmental chamber should stay open and be continuously
heated where appropriate in order to dry it internally.
SPAC SPAC S PAC SPA C
12.3 Assembling the interface board
If Humidity Chamber HC10 is not acquired together with the DSA100, but is
delivered subsequently, then an interface board and the connection socket for the
HC10 must additionally be built into the DSA100.
Page 83
Humidity chamber HC10 page 81
This is done as described in Chapter III for the axes, but with two differences:
The connection socket for the chamber is built into the left-hand side of the
rear panel of the DSA100.
The connection plate is also built in on the left. The right-hand side is reserved
for the axes.

Thermostat connection
The TC30/40 and the HC10 are connected in series. The thermostat liquid flows
from the male quick-release connector to the female quick-release connector.
Male Female
1. Connect the output of the through-flow thermostat to the input of the
environmental chamber.
2. Connect the output of the environmental chamber to the input of the HC10.
3. Connect the output of the HC10 to the input of the through-flow thermostat.
Gas connector for humidity control
Dry gas must be used for all connections when the humidity of the air used for
measurement is low. If the flow of gas is produced by a compressor then the air
must be dried if the humidity of the air used for the measurement is to be lower
than the atmospheric humidity.
Connect the connector on the throttle valve to a compressed gas connection
(1 bar).
Please maintain the specified input pressure of 1 bar.
The throttle valve reduces the pressure of the gas to 350 mbar. This is
permanently set and locked at this value. Do not try to adjust the valve.
Page 87
Humidity chamber HC10 page 85
!
!
!
Gas connector for condensation protection
Connect compressed gas for condensation protection if required
( Chapter 11.5.2).
The gas connection on the TC30/40 chamber should only be used when the
observation window is actually affected by condensation. The additional flow of
air reduces the atmospheric humidity that can be achieved and reduces the
accuracy of the humidity control.
12.5.2 Power supply / Communication
Connect the connector on the rear of the HC10 to the corresponding connector
on the rear of the DSA100 (left-hand connector plate when viewed from the
rear).
12.6 Filling / Filling level
The required liquid volume is 40 mL.
Remove the screw marked in the illustration.
Fill the chamber to the top with demineralised water.
Use only demineralised water to prevent calcification.
When the chamber is less than one-third full with water its performance falls off
rapidly. During operation you should check the filling level about once every
three hours and top up with water as necessary
Page 88
page 86 Humidity chamber HC10
12.7 Fitting the temperature sensor
Feed the temperature sensor into the opening in the environmental chamber.
Connect the temperature sensor to the connector on the DSA100 provided for
the purpose ( Chapter 5.8).
12.8 Covering the needle inlet
The needle inlet of the environmental chamber is covered in order to guarantee a
good regulation of the humidity. Silicone covers are supplied for this purpose:
three covers with small opening for sessile drop measurements
three covers with large opening for pendant drop measurements
Procedure
1. Feed the silicone cover over the dosing needle as far as it will go.
2. Set the required dosing height.
3. Slide the silicone cover down so that the cover rests on the dosing needle inlet.
