The RT-722 Capillary Rheometer boasts a beautiful appearance and strong stability and is easy to clean. It is also convenient for transportation and installation. This powerful machine can measure the shear rate of plastic processing and temperature conditions. It can determine the melt flowability under shear stress, including adhesion to the wall of thermoplastics and thermoset plastics characterization. The instrument loading device is expertly designed, with hardware and software double closed-loop to achieve stepless speed adjustment and loading force. Both manual and automatic loading controls can be used, making it convenient, fast, and accurate.

What Tests Can RT-722 Capillary Rheometer Do?
1. Constant Speed Shear Test:
Measuring shear stress and shear rate curve, and shear viscosity and shear rate curve;
2. Constant Pressure Shear Test:
Measure the shear viscosity and shear rate curve;
3. Step Shear Rate Test:
According to user requirements can be set to different shear rates, measure the shear stress and shear rate curve, and shear viscosity and shear rate curve, and in the experimental process according to the changes in the curve to determine the rupture of the melt and the melt’s minimum flow pressure and shear rate;
a) Flow/non-flow Test:
Measure the viscosity and temperature relationship, which can accurately determine the minimum flow temperature of the material;
b) Melt Rupture and Flow Instability:
to study the phenomena of flow instability, including melt rupture and melt fracture.
What Are The Advantages Of RT-722 Capillary Rheometry?
1. A wide range of force values (up to 100kN) and a wide dynamic rate range (225,000:1) allow the test to simulate the real processing environment of the material.
2. Double-hole barrels are used as a standard method to perform shear viscosity measurements and calculate ductile (tensile) viscosity at the same time.
3. Provide a variety of standard high-precision tungsten carbide die, covering a variety of materials and test types.
4. Easily interchangeable melt pressure transducer can meet all the test requirements, equipped with a low noise amplifier to optimize the measurement sensitivity at the inlet of the die.
5. A nitrogen purge option is provided to minimize the possibility of sample degradation.
6. The fume chamber discharges decomposition gas to ensure the safety of operators.
7. The barrel outlet has an open design, compatible with a variety of optional accessories, such as extrusion expansion module, melt cutter, slit die, and melt pull-out strength module.
8. Provide many optional barrel material and size specifications and can measure heat-sensitive, chemically aggressive or water-based samples.
9. RT-722 capillary rheometer also provides a high degree of flexibility for high pressure and high shear rate measurements, whether from polymer melts to ceramics, or from food to coatings.
