Anton Paar RheolabQC - Rotational rheometer for quality control

The RheolabQC is specially designed for performing routine rheological tests, from quick single-point checks to complex rheological investigations.

The RheolabQC includes innovative features such as:

Toolmaster™
the new RheoPlus software
wide speed and torque ranges, controlled shear rate (CR) and controlled shear stress (CS) test settings.

Together, these features make the RheolabQC as easy to use as a R&D rheometer and outstanding value for money. This brings innumerable benefits for the application.

As well as conventional flow and viscosity curves, the RheolabQC is also ideal for investigations into the mixing and stirring behavior of emulsions and dispersions, for testing the sagging and leveling behavior of coatings and for determining the yield point of gels and pastes.

The RheolabQC is the ideal entry-level instrument and completes the renowned Physica MCR rheometer series.

Anton Paar Physica MCR rheometer family

The new Physica MCR Rheometer Series offers four new rheometer models plus an extensive range of accessories which stand out for technical excellence and ease-of-use.

Modularity and compatibility across the Physica MCR rheometer series as well as unique features guarantee individual rheometer configurations to solve your application problems at great value for money.

Physica MCR 501 - the high-end rheometer for R&D
Physica MCR 301 - for product development and research
Physica MCR 101 - for QC and product development
Physica MCR 51 - for quality control applications

All rheometers perform a wide range of steady and dynamic tests in both CSS and CSR mode. From generating simple flow curves to the dynamic analysis of complex fluids, melts, and co-polymers, all Physica rheometers offer simple programming and test setup. Part of the flexibility of the new RheoPlus Software lies in its ability to mix or "chain" different test types together to help simulate process and end-use conditions.

Anton Paar Stabinger SVM3000 Viscometer

Viscosity measurement has never been so easy:

The SVM 3000 works according to a new, patented (EP 0 926 481 A2) measuring principle. Just fill the measuring cell with 3 ml of sample and obtain both dynamic and kinematic viscosity and density values. The viscosity index calculation is also integrated.

The SVM 3000 fulfills all requirements of the ASTM D7042: Standard Test Method for Dynamic Viscosity and Density of Liquids by Stabinger Viscometer (and the Calculation of Kinematic Viscosity).

The precision obtained by the SVM 3000 in the interlaboratory study conducted by ASTM subcommittee D02.07A was shown to be equivalent to the precision achieved in measurements made according to ASTM D445. No significant bias could be found between the methods.

The extremely high sensitivity of the eddy current torque measuring system and the integrated thermoelectric temperature control provides unrivalled precision. The torque resolution is an unmatched 50 pico-Nm. This is comparable to the torque resulting from a dust particle on a 1 cm lever arm and allows for a minimized measuring cell.

No water bath, no liquid-in-glass thermometers.
No change of capillaries - one measuring cell covers the whole viscosity range.
Equivalent precision and no bias to ASTM D445.
Minimal lab space and low power consumption.
The fastest precision viscometer ever.

Anton Paar SurPASS Electrokinetic Analyzer

The surface charge of a solid material influences the interaction with its surroundings, which makes this property decisive for many applications in technical fields and life sciences. The knowledge of surface charge is therefore of paramount importance to take influence on the solid surface behavior.

Quantitative information is available in short time with the SurPASS electrokinetic analyzer.

The enormous flexibility of the SurPASS measuring cells enables the zeta potential analysis of solids of almost any size and shape. The range of applications starts with powder samples of particle size from some tenth of microns to more than one millimeter. The same measuring cell accomodates fibre material of different origin like glass, carbon or textile fibres. The step towards samples with planar surfaces only requires the exchange of the measuring cell.

High throughput of samples is nowadays a stringent requirement not only for industrial applications. The quick exchange of the measuring cells and little effort for sample preparation decrease the downtime of the SurPASS.

Knowledge of the electrolyte pH and its influence on the zeta potential are essential for the understanding of surface charge and chemistry. The integrated titration unit allows a fully automated investigation of zeta potential depending on pH and other liquid properties within short measuring time.

Anton Paar SAXSess High-Flux Small-Angle X-ray
Scattering (SAXS) Instrument

The SAXSess is an instrument for structural characterization in the nanometer range.

Due to the design of the SAXSess the X-ray intensity at the detector is very high and consequently measurement times are short.

The use of an advanced CCD detector makes time-resolved SAXS experiments possible and results in a high sample throughput.

The SAXSess enables to perform simultaneous measurements up to scattering angles of 40° with the same excellent resolution as required for SAXS. No reassembly, no realignment nor intermediate handling of samples is necessary.
