Mooney Viscometer

Shimadzu logo

The SMV-301 and SMV-301RT are Mooney Viscometers made for testing properties such as Mooney viscosity, scorch time, and stress-relaxation of rubber samples.

Complies with international standards

The SMV-301/301RT is designed to perform Mooney viscosity, minimum Mooney viscosity, and scorch time measurements as specified in ASTM, ISO, and JIS standards. Additionally, stress-relaxation, cyclic, and variable rotor speed measurements can also be performed with the SMV-301RT.

Windbreaker and rotor lifting feature provide ease-of-use, safety, and efficiency

The supplied windbreaker insulates the sample and testing surfaces from external disturbances that may affect experiments. Safety settings also prevent testing from starting until the windbreaker is closed to prevent exposure to hot surfaces and finger pinching from the rotor cover. Tests can be started at the touch of a button, making runs easy and efficient.

Windbreaker

Upon finishing a test, the rotor must be cleaned to ensure that the next sample can be tested without contamination. The SMV-301/301RT rotor lifting function automatically lifts the rotor to allow for easy access and removal. Rotors are also treated to prevent samples from sticking to them, which makes cleaning easier.

Software

The SMV-301/301RT can be run using the LCD touch screen panel to allow for evaluation of materials during in-line processes. Test conditions and file parameters can be set using the intuitive graphical interface.

LCD Touch Screen

The auto-start function is enabled when the windbreaker is closed. Once this is done, the Standby button can be pressed to start a run with the set parameters. When this is done, the crosshead will be lowered automatically and the test will start.

Time vs Mooney Value Graph

Once the run(s) are finished, data can be examined from the panel. By setting pass/fail conditions, samples can be quickly monitored to see whether the sample falls within specifications. Detailed sample results can also be examined. Reports can be printed out after connection with a PC or using an optional on-board printer.

Stress Relaxation Results

When multiple runs have been performed, statistical data can be visualized through either a scatter plot or a histogram.

The SMV-301/301RT can also optionally be run from a PC, where the SMV-301 software can run up to four separate instruments on a single PC.

SMV-301 Software Screen

The PC software provides an even more intuitive layout and power for the SMV-301/301RT by providing a sleek interface for users to set the necessary parameters needed for their measurements. Statistical analyses are made even easier with the ability to easily select multiple measurements to examine.
