Brabemder ICC-Standard no. 169 AACC Method no. 61-01 Viscograph®-E The standard for the measurement of starch . where quality is measured. Viscograph®-E The Viscograph® measures native starch - wheat, corn, potato, rice starch - just like all types of modified starch reliably and reproducibly. Get a complete profile of the rheological properties of your products: • Gelatinization and gelification properties of starch and starch containing products • Hot and cold viscosity • Stability of thickening agents or binders • Acid stability of starch • Caustic gelatinization (Alkali-Brabender®) • Extrudate testing • Measurement of industrial starch (technical and native) Features • Automatic test procedure • Storage of any number of temperature programs Heating/cooling rates of 0.5...3°C/min (in certain sections of the temperature cycle up to 5°C/min) • Electronic speed control • Low-deflection torque measurement • Free selectable measuring ranges • Automatic adaptation of the diagram scaling to the viscosity measured • Comfortable measuring and evaluation software under Windows • Speed profiles • The evaluation is done in BU, mPas or cmg The principle The Viscograph® - which has been the standard instrument worldwide for measuring the viscosity of starch and products containing starch - has now got a completely new, compact design. The sample is heated up within a rotating stainless steel bowl and cooled down again, both under controlled conditions. Together with the comfortable Windows software, the integrated, self-optimizing temperature controller allows programming and storage of any temperature profiles with heating/ cooling rates of 0.5...3°C/min. A measuring sensor reaching into the sample is deflected according to the viscosity of the sample in the bowl. This deflection is measured as torque. The Viscogram Get reliable and reproducible data about the rheological properties of your material - thick or thin boiling, different thickening capacities, gelification, high or low hot and cold viscosity, stability, etc. • Beginning of gelatinization (A) • Gelatinization maximum (B) Gelatinization temperature • Viscosity during holding (B-C) Viscosity at the end of cooling (D) Viscosity Sample curve Made in Germany since 1923. Software Enter your test parameters from your computer keyboard and store them as a "method" - a single mouse click opens your test routine at any time. The PC transmits your temperature profile to the controller and the test runs automatically. On-line display of the Viscogram keeps you informed of progress through the test. After the test, all relevant data are calculated fully automatically. Tests can be run in an administrator or operator mode. Define and assign authorities in the administrator mode or create and save automatic test procedures including a description of the test procedure for your laboratory staff. Data correlation The data correlation program allows a direct comparison of up to 15 Viscograms with each other by contrasting test conditions and results in a graphic and tabular form and evaluating them statistically. Or get a quick overview of all Viscograms from the correlation diagram. Universal evaluation Use this new, additional software package for defining evaluations of your own. Manifold defined formulas allow you to Evaluate e.g. the maximum or minimum within a certain, defined time range Search for the first time when a predefined viscosity is reached in the test Evaluate in own defined temperature, time, or viscosity steps Evaluate e.g. the time between a certain temperature and reaching a certain viscosity, etc. Area calculation / energy ^___________ SED m ■- / --- _. — - - ,: The data correlation Viscograph®-E Sample volume approx. 450 ml Heating capacity 550 W Heating/cooling rate 0.5...3°C/min*> Speed profiles 0...300 min-' Torque measurement electronically PC port USB Mains connection 1x 230 V; 50/60 Hz + N + PE;2.8A 115 V; 50/60 Hz + PE;5.6A Dimensions (W x H x D) 560 x 890 x 430 mm Weight approx. 30 kg net ) for special applications in certain sections of the temperature cycle up to 5°C/min Brabender® GmbH & Co.
