Starch Pasting Viscometer - Rapid Visco Analyzer - 20-50,000 cP - 15°C/min Ramp

The Master Science Starch Pasting Viscometer is a programmable rotational viscometer for measuring the stirring and gelatinization behaviour of starch. It is used to assess starch quality in wheat, maize, rice, sorghum, potato, lotus root and other crops, as well as in starch-based food ingredients.

Only 2 to 3 g of sample is needed. The instrument heats and cools the sample at up to 15 °C/min while changing shear rate on a user-defined program, then calculates the full pasting profile automatically.

Key Benefits

• Repeatable profiles: direct temperature measurement in the sample can and precise heating and cooling keep curves consistent.
• Uniform mixing: a specially shaped paddle prevents starch granules from settling during the test.
• Rich analysis: the Master Science Starch Pasting Viscometer reports up to 20 extended results such as time to target viscosity.
• Traceable reports: administrator control, locked reports and one-click export to Excel or PDF.
• Small sample need: a full test uses just 2 to 3 g.

Other rheology and physical test instruments are listed in the Master Science laboratory instrument range.

Common Laboratory Problems and How This Viscometer Helps

How the Master Science Starch Pasting Viscometer supports starch quality testing:

• Slow traditional amylograph tests: short programs deliver a full curve quickly.
• Settling of starch during heating: paddle geometry keeps the slurry uniform.
• Inconsistent temperature ramps: programmed heating and cooling are precise.
• Manual curve interpretation: key parameters are calculated automatically.
• Report tampering concerns: locked reports and traceability protect data.
