Viscograph®-E
Application
The Viscograph®-E is the standard instrument worldwide for measuring the viscosity of starch and products containing starch. The instrument measures native starch - wheat, corn, potato, rice starch – just like all types of modified starch reliably and reproducibly and supplies 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
- Extrudate testing
- Measurement of industrial starch
- Measurement of liquids, suspensions, pastes, etc.
Principle
The sample is heated up within a rotating 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 profi le 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.
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. from
- Beginning of gelatinization (A)
- Gelatinization maximum (B)
- Gelatinization temperature
- Viscosity during holding (B-C)
- Viscosity at the end of cooling (D)
