Product news

The RST Series of touch screen rheometers represent the best that AMETEK Brookfield has to offer – instruments that operate both in controlled shear rate (rpm) and controlled shear stress (torque) modes – for sophisticated rheological analysis. With automatic data collection and analysis using optional Rheo3000 software, RST Rheometers offer greater flexibility and more features than other high-end rheometers in their class – at a fraction of the cost.

RST Rheometers have a durable design with rapid bob (spindle) attachment and easy-to-clean surfaces for years of trouble-free operation. Increased measurement capabilities range from simple single-point viscosity tests to comprehensive rheological profiling. Evaluate material behavior from initial yield stress through full flow curve response at variable shear rates to relaxation, recovery and creep.

The RST touch screen series is available in three configurations and all models feature:

  • Controlled stress/rate operation to analyze comprehensive flow behavior
  • User friendly LCD touch screen with graphical display
  • 11 memory slots for structured multi-step test programs
  • Auto spindle identity recognition
  • Quick connect coupling for easy spindle attachment
  • Optional Rheo 3000 Software for PC control and data management
  • 21 CFR compliance for controlled user access and data security

Some popular applications include: adhesives, biomass, chocolate, dairy, gypsum, pesticides, pharmaceutical, pigment dispersions, sauces, syrups and sludge, slurries and concrete.

The most common types of rheometer include shear rheometers (capillary, cone and plate and rotational cylinder) and extensional rheometers. Viscometers are similar to rheometers however viscometers only measure the viscosity of a fluid.PesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA. Food QualityFood quality refers to the attributes of food that influence its safety, nutrition, and taste. Monitoring and ensuring food quality are essential in production to meet health regulations and consumer expectations.
