I. General Description

This section has general information about the instrument and operating principles.

I.1 Use of the Rheometer

The R/S+ Rheometer will measure viscosity of Newtonian and Non-Newtonian materials in
controlled shear rate (CSR) or controlled shear stress (CSS) modes. The instrument can measure
simple viscosity at a given speed or shear rate, or measure fl ow properties with a fl ow curve at
shear rates up to ~1,200 sec-1.

In controlled stress mode, the instrument can do a direct yield test (stress ramp) and indicate
elasticity with creep/recovery tests.

I.2 Measuring Principle

The R/S+ Rheometer is a rotational, controlled shear stress instrument which can be operated in
controlled shear rate mode.

Concentric cylinders, measuring cones and plates are available as a measuring system. The
measuring sample is positioned in a measuring gap between the stationary measuring cup and
the rotating measuring bob (Searle-principle), respectively between the rotating cone or plate and
the stationary lower plate (cone/plate, cone/cone measuring system).

The measuring drive developed for this instrument operates with a high precision, dynamic drive
system with optical encoder for absolute position measurement of spindle geometry.

The R/S+ measuring drive can operate at a pre-set of speed (shear rate) or pre-set of torque (shear
stress). Measurements may be made in manual mode (without PC) or under PC control with Rheo
3000 software. Note that the creep measurements require a computer system with Rheo 3000
software.

Both CSR and CSS measurements can be carried out manually (without PC support) or with a
computer system and Rheo 3000 software.

Brookfi eld Engineering Labs., Inc. Page 12 Manual No. M08-219-B1211

Insert the plug for the Pt100 connector in the back of the rheometer head.

Since viscosity is a function of temperature, the temperature should be preferably measured in the
test fl uid. For this purpose, the standard measuring systems 8 mm to 40 mm DIN can be equipped
with a Pt100 in the measuring cup bottom when the water jacket is used. If you use a measuring
system with built-in Pt100, this is where you will insert the cable VK-Pt/RC.

III.2.2 AC Adapter

Do not use a power supply other than the AC adapter delivered by Brookfi eld for the R/S+
Rheometer.

Connect the AC adapter using a grounded plug to avoid electric
shock or damage to the system components!

Connecting the AC adapter:

Turn the R/S+ Rheometer off with the “POWER” switch at the back side of the

­instrument.
Connect the RS+ power cord into the AC adapter.

­Insert the socket of the DC cable into the “DC” connector port at the back side of the

­instrument.
Plug the power cable into a grounded AC power socket.

­Turn the R/S+ Rheometer on.

-

Do not leave the power supply plugged into the AC power socket when the cable to the
rheometer is un-plugged!

Before disconnecting the rheometer from the AC supply, be sure that the instrument is

IV. Environment, Handling, Cleaning and Maintenance

IV.1 Operating Environment and Storage

Find a convenient work place for the installation of the R/S+ Rheometer. There should be enough
room to place the rheometer, the measuring systems, the measuring substances and the peripheral
devices (e.g. printer, computer and bath/circulator). You need a grounded AC plug to operate
the R/S+ Rheometer and additional plugs for the connection of each peripheral device (i.e. Bath,
Peltier). Your operating environment and the place where you store the R/S+ Rheometer should
not be extremely hot, extremely cold or extremely moist. Places with large temperature and air
humidity variations should be avoided. Be sure that the R/S+ Rheometer is not exposed to the
following:

heavy dirt or dust

•

direct sun

•

•

objects that emit heat (e.g. heating radiators)

•

objects with a strong electromagnetic fi eld (e.g. loudspeakers, motors etc.)

•

liquids or corrosive chemicals

IV.2 Handling

The R/S+ Rheometer is designed to endure light bumps or vibration. Avoid dropping it or exposing
it to heavy shock!

Never lift your RS+ Rheometer at the measuring bob coupling or with
the measuring bob attached to the instrument.

Always disconnect the bob at the bob coupling before removing the
sample cup!!!!

The rheometer motor will automatically turn off if the maximum torque (50 mNm) is exceeded.

IV.3 Cleaning

The paint coat of the R/S+ Rheometer resists most usual solvents and weak acids. Use a dry, clean,
soft and nap-free piece of cloth to clean the housing. Use neutral detergent liquids, if necessary.

Do not use chemical products such as strong solvents or strong acids to
clean the housing, especially the keyboard.

Brookfi eld Engineering Labs., Inc. Page 19 Manual No. M08-219-B1211

IV.4 Maintenance

The R/S+ Rheometer system is designed for long-term operation. Should the instrument require
repair, contact Brookfi eld or your Brookfi eld dealer.

Only authorized service personnel may work on the control
electronics, all accessories, the measuring drive, as well as the AC
Adapter and all electric circuits and connections!

Measurement accuracy can be checked by the user at any time. We recommend that the
measurements be done with Brookfi eld viscosity standard fl uids (mineral oils) as recommended
for each individual spindle geometry.

You must:

Use temperature control (i.e. water jacket and circulating bath)

•
Select the appropriate measuring system

•
Carry out measurements at the following pre-set M (‰ torque): 250‰, 500‰ and 750‰

•
Read viscosities from the display

•

In case of instrument failure (or severe deviation from the preset value), contact Brookfi eld or
your Brookfi eld Dealer.

Brookfi eld Engineering Labs., Inc. Page 20 Manual No. M08-219-B1211

V. Measuring Systems

V.1 Measuring Directly in the Sample Container

You may immerse the measurement system directly into a container of sample by removing the
cap on the bottom of the immersion cups.

When using the double gap bob measuring system, do not damage the “O” ring which forms the
seal between the inner and outer parts of the sample cup. To clean, the inner section is removed
by unscrewing the (stainless steel) ring at the bottom and then GENTLY push the inner section
out through the bottom of the outer section. Take care not to damage or stretch the O-ring seal
during removal! Insert the inner part again and screw the ring back on.

General steps for direct immersion of the measuring system into the bath:

Lift the coupling sleeve of the measuring bob coupling (the ring is visible).

•
Insert the measuring bob into the measuring bob coupling.

•
Lower the coupling sleeve (the ring is covered).

•
Fasten the measuring cup at the measuring cup mounting fl ange with the measuring cup

•
ring.
Immerse the measuring cup into the substance up to the ring mark or up to the point where

•
the diameter of the measuring cup increases.

Fig. V-1: Depth of immersion

Do not get sample in or onto the measuring bob coupling.

After making your viscosity measurement, unscrew the measuring cup ring and remove the
measuring cup. Open the measuring bob coupling, and remove the measuring bob.

Clean the measuring cup and measuring bob carefully. Do not use abrasive cleaning tools, and
always prevent scratches! Store measuring bobs on a soft pad.

Brookfi eld Engineering Labs., Inc. Page 21 Manual No. M08-219-B1211

V.2 Measurement by Filling the Sample Cup

Fill the measuring cup with your material (see Appendix A.1 for sample volume). Avoid air
bubbles when fi lling the sample as they can affect the repeatability of the test!

Place the measuring bob into the measuring cup. Lift the coupling sleeve (the ring is visible).
Insert the complete measuring system into the measuring cup mounting fl ange from below and
screw on using the measuring cup ring. Now, insert the measuring bob shaft completely into the
measuring bob coupling and lower the coupling sleeve (the ring is covered).

If you want to measure with temperature control, the bath/circulator must be pre-set at the desired
temperature and you should wait until bath liquid and sample are at test temperature.

To remove the measuring system after the viscosity measurement has been completed, fi rst open
the measuring bob coupling and then unscrew the measuring cup thread.

When unscrewing the measuring cup, you must hold the measuring
system tightly with one hand to avoid dropping the cup and bob!

Clean the measuring cup and measuring bob carefully with a soft cloth to avoid scratches!

V.3 Measurement with Water Jacket Assembly

Install the FTKY3 jacket by removing the measuring cup ring on the rheometer (see Figure III.5).
Attach the jacket to the rheometer using the ring built onto the top of the jacket.

Connect the tubing from the bath (the bath outlet to the bottom tubing connection of the jacket;
the bath inlet to the top of the connection on the water bath) to the jacket , and connect the Pt100
on the jacket to the Pt100 socket on the back of the rheometer.

When using disposable measuring systems, insert the disposable measuring cup into the receptacle.
Fill the measuring cup with the sample. (See Appendix A.1 for sample volumes).

Avoid air bubbles when fi lling the sample as they can affect the repeatability of the test!

Place the measuring bob in the measuring cup. Lift the coupling sleeve (ring is visible). Insert the
cup and bob into the jacket from below and screw on using the measuring cup ring. Insert the bob
shaft into the measuring bob coupling and lower the coupling sleeve (ring is covered).

Set the water bath to test temperature. After the bath is at the test temperature, wait 15 minutes
to ensure that the sample, cup and bob are at test temperature.

Brookfi eld Engineering Labs., Inc. Page 22 Manual No. M08-219-B1211

To remove the measuring system after the measurement, fi rst open the coupling sleeve for the
bob, then unscrew the measuring cup ring.

When unscrewing the measuring cup, you must hold the measuring
system tightly with one hand to avoid dropping the cup and bob!

When using disposable measuring cups, eject the disposable measuring cup with the pusher.

V.4 Measurement with Cone/Plate or Plate/Plate Measuring Systems

Installing and adjusting the measuring cone or measuring plate

When installing a cone or plate, the lower plate must be in the down position (move the locking
lever to the left and gently pull the lower plate down).

When releasing the bayonet lock, the measuring device has to be held
tightly from below.

Loosen the set screw on the cone or plate and push the cone or plate bottom up, setting the shaft
length to the minimum.

Lift the coupling sleeve (red ring mark should be visible). Insert the cone or plate from below into
the measuring coupling. Lower the coupling sleeve (ring is covered) to attach the spindle.

Turn the adjusting screw on the plate down to the lowest position. Raise the plate to the top
position and secure it with the bayonet lock (position “closed”).

The actual distance between spindle and plate has to be adjusted to approximately 1 mm by
turning the adjusting screw up. Set the screw mark to “0” with approximately 1 mm between
cone and plate.

The dial indicator should also be set to mark “0” for distance control. Unlock the spindle shaft
to bring the spindle onto the plate, and tighten the cone set screw to fi x the shaft.

The plate is now adjusted to 50 μm. The adjustment ring lowers the plate down when turned
clockwise (looking down onto the adapter), and raises it up by turning the ring counter-clockwise.
Lower the plate to 0.5 mm by turning the adjustment ring clockwise for one complete revolution.
Now raise the plate, but not all the way back to the zero position; stop at the “5” mark in the ring
which sets the gap to 50 μm.

Measurement

Open the bayonet lock and lower the plane-table. Apply the sample to be tested. Lift up the plane­table and fi x the bayonet lock. Now, the measurement can start.

Remove excess sample from around the cone or plate before starting the
measurement.

If temperature control is required, a bath/circulator must be connected. The bath must be set at
the desired temperature, and you should wait until the bath and cone/plate accessory have reached
test temperature.

VI.4 Input of Numerical Values and Alphanumeric Texts

Most user defi ned entries are numbers. User defi ned values such as the Start and End values
of a ramp, number of measuring points, factors, time, date, etc. are entered as numbers with or
without decimal digits.

If the display shows the decimal point in a number to be entered, input of a fl oating-point number
is requested. However, the number of digits after the decimal point is limited to the number of
displayed decimal digits; i.e. the decimal point cannot be moved during input. The digit to be
changed is indicated by a bar under the digit.

The following examples indicate the input of numerical values. We will change the value of shear
rate (Val.[1/s]) from 0100.00 to 290.00.

In the example below, the cursor bar is located under the “1” in the entered shear rate (currently

100.00 s

This example shows that the measurement data will be written into the instrument memory. Output
devices are either a printer or the RS232 serial interface of the rheometer. Pre-selection of these
devices is described in Section VI.7.1: Confi guration → Output Mode.

If the memory is full and you want to keep the data, you should stop the “Single Measurement”
function and print out the data from the memory or send the data to a PC (see Section VI.6.5:

Utilities → Print Memory). Then you may clear the data from the memory (see Section VI.6.1:
Utilities → Clear Memory) and run your test.

Tests may still be run if the memory is full, but the results will not be saved. They will be shown
on the LCD as they come from the instrument.

When a measurement is started, the instrument shows:

VI.6.2 Utilities → Edit Program

This function allows the input of new programs and the modifi cation of existing programs. These
programs may be run after a successful creation via the menu level “Program Measurement” in
the main menu.

The following values are user-defi nable in a program:

• measuring system to be used

• number of steps

• start and end value of each step

• number of measurement points for each step

• duration of each step

Steps are always linear, measurement points are also defi ned as linear; i.e. logarithmic steps are
not possible. For logarithmic measurements, you will need the Rheo 3000 software.

Preset value sub-steps in a defi ned step according to the following equation:

Preset Value = End Value - Start Value/(Number of Measuring points - 1)

The fi rst user defi ned value (= the fi rst measuring point) is always the start value of the ramp.
The last measuring point is determined as the end value of the user defi ned value range. As in
our example, to reach the values D = 10, 20, 30, ... , 100 [s

VI.8 Serial Data Transfer via the RS-232 Interface

Serial data transfer should only be done when the user of the rheometer has basic knowledge
of data processing and is capable of changing the data transfer parameters on the sending and
receiving sides.

Data can only be transferred successfully when the transmitter (R/S+ Rheometer) and receiver
(e.g. a PC) fulfi ll the following requirements:

The instruments are properly connected by the interface cable which is delivered with the

1.
instrument. Caution: Both instruments must be switched off while the connection is
made! (see Appendix A.3: Pin Assignment of the Serial Data Cable).
The transmitter (R/S+ Rheometer) and the receiver are set to identical data transfer parameters

2.
(for R/S+ Rheometer, see Section VI.7.5: Set RS-232 Parameters).
The receiver has enough computing and memory capacity to receive or store the data.

3.

The following example demonstrates reception by means of the terminal program under
Microsoft™ Windows.

Switch the rheometer and the PC off.

Appendix B Calibration Check Procedure Appendix B Calibration Check Procedure

B.1 Using Rheo 3000 B.1 Using Rheo 3000

Calibration is checked using a mineral oil viscosity standard with a three step test in CSS (controlled
shear stress) mode at torque values of 250‰, 500‰ and 750‰ (12.5 mNm, 25.0 mNm and 37.5
mNm respectively). The viscosity over all three steps is averaged and the average should be ±3%
of the viscosity standard value.

Example: A viscosity standard of 1.059 Pa*s should give an average viscosity between 1.02723
Pa•s and 1.09077 Pa•s.

The test program, shown in Figure B-1, shows the three blocks of the program. Block 4 is the
basic analysis that calculates the average viscosity and Block 5 is the fi nal calibration report
which may be printed.

Figure B-1: Test Program for Calibration Check Procedure

Note that, in all cases, the shear rate for each stop of the test must be under 500 sec-1 to avoid
sample heating.

Appendix C: RS4SSTB Rheometers for Measuring in Brabender Units (BU)

R/S-SST instruments equipped with BU software (rheometer part numbers RS4SSTB115LS and
RS4SSTB230LS) are used with spindle geometry RSS-90Y (used with instrument serial numbers
beginning 304 or 702) or RSS-89Y (used with instrument serial numbers beginning 302 or 303)
for testing according to ASTM C474.

The RSS-90Y/RSS-89Y have three parts (see Figure C-1): the Spindle Adapter (which connects
to the rheometer), the BU Spindle Type A and the Thumb Screw (which secures the Spindle in
the Spindle Adapter).

manual and the onboard Help fi le.

D.1.2 Soft Solids Analysis Functions

Clicking on Soft Solids Analysis opens the analysis functions for soft solids testing.

The soft solids analysis functions enable the quantifi cation of properties of tested materials using
regression analyses and peak-value identifi cations:

Yield / Modulus

The peak value within the data range is reported as yield point values for stress and torque. The strain
and angular displacement at the yield point are also reported.

A regression is performed on the range defi ned in confi guration and the gradient of the stress vs. strain
curve is reported as Modulus. The regression coeffi cient, B, and the standard deviation, S, is also
reported.

Creep

Two regressions are performed on the creep data to obtain:

Instantaneous Response: A regression is performed on the range defi ned in Confi guration to obtain
values for instantaneous compliance, strain and angular displacement.

Viscous Response: A regression is performed on the range defi ned in confi guration to obtain creep
viscosity. The intercept on the y axis (strain, displacement or compliance) is then divided by the maximum
value (last data point) of the creep curve to obtain Elastic Index.

Brookfi eld Engineering Labs., Inc. Page 66 Manual No. M08-219-B1211

Confi guration

Modulus: The upper and lower limits of the range for the modulus regression is defi ned here as percentages
of the peak value. A typical range is 20% to 70%, but these should be altered to accommodate longer
or shorter linear regions.

Creep: The number of points for the regressions for Instantaneous Response and Viscous Response are
entered here. Typical values are 5 points and 20 points respectively.

D.1.4 Editing and Running Programs

As detailed in the R/S Rheometer operation manual, stand-alone programs can be written
under the Section VI.6.2: Utilities

→ Edit Programs menu for the R/S-SST+ to facilitate fast

test turnaround.

D.2 Getting Started in Soft Solids Testing

The two test methods that are most often used to evaluate soft solids with the R/S-SST+ are the
Constant Rate Test and the Creep Test.

D.2.1 The Constant Rate Test

For products like: Stiff pastes, slurries, set gels, waxes.

Properties measured: Yield stress or torque, equilibrium stress strain at yield, rigidity
modulus.

Description: In the constant rate test, the vane is rotated at a constant low rotational rate (typically

0.1 to 0.5 rpm) and the torque or stress is measured against time, rotational angle or strain.

Example method: Constant rotation at 0.2 rpm, linear data collection, 60 data points over 60
seconds. A V30-15 vane (30 mm high by 15 mm across) is used in an open confi guration (see
Section D.3.3: Setting Up Vanes).

Figure D-3

Brookfi eld Engineering Labs., Inc. Page 68 Manual No. M08-219-B1211

Typical results plots:

CR Test on mayonnaise with stress (Tau,
in Pascals) plotted against strain (Gamma,
unit-less).

The peak value is yield stress. The gradient
of the stress/strain up curve indicates gel
rigidity, a steeper curve: a stiffer gel and
vice-versa.

Figure D-4

Mayonnaise shows a distinct gel breakdown after the peak yield point. Other samples, such as some
pastes and slurries, may not peak but instead equilibrate at an equilibrium stress plateau:

CR Test on toothpaste. Equilibrium stress
is an indication of low shear viscosity or
“consistency”.

Figure D-5

D.2.2 The Creep Test

For products like: gels, custard, gravies, sauces, jams and marmalades.

Properties measured: Instantaneous compliance/strain, low shear viscosity/creep rate, elasticity
index.

Description: A single stress/torque is applied at time (t = 0) and maintained on the sample over a period
of time, usually between one and fi ve minutes. The degree of subsequent movement in the sample, is
recorded against time in the form of angular displacement (in radians), strain (unit-less) or compliance
(strain divided by applied stress – in m2/N).

Example method: A constant stress of 1250 Pa is applied over a period of 120 seconds. 60 data points
are collected over this period.

Brookfi eld Engineering Labs., Inc. Page 69 Manual No. M08-219-B1211

Typical results plot:

Figure D-7

D.3 A Few Tips To Get You Started

Figure D-6

Creep test on fruit conserve. Angular dis­placement (Phi, radians) is plotted against
time.

Short timescale response relates to elas­tic behavior and long timescale response
relates to viscous behavior. So, a high
initial angular displacement indicates a
flexible “wobbly” gel structure while a
steep gradient at long timescales means
a product that creeps easily, that is, it has
a low low-shear viscosity.

It is important to operate the R/S-SST+ at torque values that are within the R/S-SST+’s reliable range
of 30‰ (3% or 1.5mNm) to 1000‰ (100% or 50mNm). In creep testing, the minimum recommended
applied torque is 75‰ (3.75mNm).

Brookfi eld Engineering Labs., Inc. Page 70 Manual No. M08-219-B1211

If you prefer to work in stress values, then these torques equate to the following for our standard
vanes:

Constant Rate Test Creep Test (recommended minimum

V30-15 121 Pa to 4040 Pa 303 Pa

V40-20 51 Pa to 1700 Pa 128 Pa

V80-40 6.4 Pa to 213 Pa 16 Pa

D.3.1 Vane selection

The fi rst consideration in vane selection is the working torque ranges just mentioned. The next
consideration relates to vane-to-container diameter ratios. The vane measuring method works best
when these ratios are lower than 0.75. Low vane/container ratios allow the measurement of samples
with large particulates to be dispersed throughout. You can also apply low strains to our sample while
still operating at angular displacements well within the instrument range.

Ideally, the vane should be immersed in a sample of a depth twice that of the vane height. This is,
however, very often not practical but the user should at least ensure ample clearance between the lower
end of the vane and the base of the container, especially when measuring large-particle suspensions.

D.3.2 Container Dimensions

For yield point measurements, the container dimensions are largely irrelevant. For creep tests and strain,
or modulus measurements in constant rate tests, the container diameter does come into effect, especially
with higher diameter ratios, and must, therefore be, entered into the measuring system setup details in
the Meas-Editor utility program. For diameter ratios of less than 0.2 for vane diameter to container
diameter, minor changes in the container size, design or positioning can be more or less ignored for
most applications.

D.3.3 Setting Up Vanes In Measuring System Editor

Before you can use a vane, its details must be set up in Meas-Editor.

Open Meas-Editor

1.
Click New

2.
Enter the name of the vane (eg V80-40) and select Type → Vane.

3.
Enter the factors K-Gamma and Tau_Prom that were supplied with the vane.

4.
Enter the radius of the vane ( Radius i ) and the radius of the container ( Radius o ).

5.
Click Save.

6.
Repeat as necessary and close Meas-Editor.

D.4 Vane Constants For The Soft Solids Tester

D.4.1 Stress Constant: τ

All standard vanes supplied for the Soft Solids Tester have a height (H) to diameter (D) ratio of 2:1. A
stress constant is required for each vane to convert torque in Newton meters to shear stress in Pascals.
This constant is calculated as follows:

The constants for the standard vanes are as follows:

V3-10-5 5 10 109.206

V3-20-10 10 20 13.651

V3-20-20 20 20 2.986

These are pre-loaded in the Rheo 3000 software. If you do not have these vanes available in Block
Editor or on your instrument, then please load them using Meas-Editor for software driven setups, or
see Section VI.6.4: Utilities → Measuring Systems for stand-alone setups.

D.4.2 Strain/Rate Constant: K-Gamma

The constant K-Gamma converts the rotational rate or position into shear rate/strain values. Its value
is dependent upon the ratio of container-to-vane diameter. The vanes pre-loaded into the Rheo 3000
software (e.g. V40-20-3 to 1) assume a ratio of 3:1. If you use vane/container combinations that don’t
match this, you will need to set up a new measuring system in Meas-Editor or see Section VI.6.4: Utilities

→ Measuring Systems. You can calculate out the required value using this equation:
