Double Gap Geometry for Pressure Cell
Suitable for Thermo Scientific HAAKE MARS & Thermo Scientific HAAKE RheoStress rheometers.
A new measuring geometry for the pressure cell D400/300, which extends the measuring range down to lower viscosities, is now available. This double gap cylindrical geometry PZ DG 34 Ti, as schematically illustrated in Fig. 1, consists of two parts. The inner part – designed as an insert – is at the same time the bottom lid of the pressure cell and is equipped with two ports: One port for filling the sample into the cell and one port for adapting a temperature sensor to monitor the temperature of the sample during the measurement.
Sample Hoods with Integrated Solvent Trap for Plates/Cones and Cylinders
Suitable for Thermo Scientific HAAKE MARS & Thermo Scientific HAAKE RheoStress rheometers
A new series of universal sample hoods were designed for the HAAKE rheometers for use in combination with parallel plate, cone & plate and coaxial cylinder geometries. The use of a hood is recommended for measurements at temperatures beyond ambient conditions, when an inert gas atmosphere is required or in order to prevent solvent los
Spectroscopical Insight into Rheology
Suitable for Thermo Scientific HAAKE MARS
With the Rheonaut a compact module has been developed* to investigate structural changes of a material on the molecular level using FT-IR spectroscopy.
With the patented Rheonaut module a standard FT-IR spectrometer with side port and the Thermo Scientific HAAKE MARS rheometer is coupled to form one measuring unit.
The Rheonaut technology enables a new level of understanding of rheological properties and processes, which depend on changes on the molecular structure. On the one hand, deformations and orientations of molecules as function of shear can be monitored. On the other hand the insitu-spectroscopy enables the investigation of chemical reactions in the measuring gap such as chemical or thermal curing of polyurethane (PU)- or epoxyadhesives.
Normal Force option
Suitable for Thermo Scientific HAAKE CaBER 1
The capillary breakup technique as used in the extensional rheometer Thermo Scientific HAAKE CaBER 1 is a powerful tool to determine the extensional properties of fluids by measuring the decline of the diameter of a stretched fluid filament, which is narrowed down by the capillary force as a function of time. For certain samples however, the physical properties of the sample, e.g. a specific sample structure or the lack of a substantial surface tension, limit the use of this
technique. In order to be able to measure the extensional properties of such samples with the CaBER 1 a different measuring approach is needed.
With the normal force option, a compact module has been developed to investigate the normal forces that arise in the fluid filament during the initial stretching. Any existing CaBER 1 instrument can be equipped with this sensor
Exchangeable Lower Plates for Temperature module
Suitable for Thermo Scientific HAAKE MARS
For cone/plate as well as plate/plate measuring geometries it is important that the effective diameter of the lower plate matches the diameter of the upper plate in order to achieve correct measurement results.
For the HAAKE MARS III temperature modules matching lower plates are available for all upper plates and cones (diameters 8 to 60 mm). The standard plates are made out of stainless steel. Inexpensive disposable plates made out of
aluminium, as well as plates with different surfaces (smooth, serrated, sand blasted) are available also. Customised versions are available on request.
Temperature Control Unit Peltier Cylinder
Suitable for Thermo Scientific HAAKE MARS & Thermo Scientific HAAKE RheoStress 6000
A new Peltier temperature control unit for coaxial cylinder geometries as well as plates and cones has been developed to complemented the series of temperature control modules for the Thermo Scientific HAAKE MARS and HAAKE RheoStress 6000 (and its predecessor models). The module fulfills the highest requirements with regards to performance as well as handling. The module can be adapted to the rheometer within seconds thanks to quick fit couplings, selfcentering and auto-recognition
Flexible Holder
Suitable for Thermo Scientific HAAKE MARS
An infinitely adjustable holder which can be attached to the optional mounting rods is available for the rheometer platform MARS. Individual components with a weight up to 4 kg can be mounted and optimal adjusted with this holder. A camera (e.g. FOculus type) for example, can be used to observe the sample during a measurement. The camera focusing on the measuring gap provides images, which can be stored along with the rheological data in the rheometer software RheoWin for further analysis of the measuring data.
Adapters for Extending Viscosity Measuring Range
Suitable for Thermo Scientific HAAKE Viscotester
The rotational viscometers HAAKE Viscotester C, D and E are described in the standard ISO 2555. The model C is suitable for the simple, fast and exact manual measurement of the viscosity and the model D for routine measurements of the viscosity with data transfer. The expert model E enables automatic measurements of flow curves with PC connection. All 3 models are available in two versions: whereas the ’’L’’-version is suitable for measurements on low and medium viscose samples, the ’’R’’-version can be used for medium and higher viscose materials
