High-Temperature Viscometer for Bitumen, Waxes, Polymers, and Adhesives

Anton Paar’s ViscoQC rotational viscometer with the ETD 300 heating chamber setup for high-temperature measurements is designed to provide a stable and precisely controlled environment for samples such as bitumen, waxes, hot melts, and polymers. The temperature device offers a temperature range from 25 °C to 300 °C, is fully controlled via the viscometer’s display, and requires no additional temperature controller or PC. The setup is compliant with widely used standards like ASTM D4402, D1986, D3236, D6267, and many more.

T-Ready^TM: For the highest sample temperature precision

Accurate temperature control is essential for viscosity measurements, as a deviation of 1 °C can make a difference of up to 10 % in viscosity values. Samples with high specific heat capacity and low thermal conductivity (e.g. bitumen, waxes etc.) therefore require long temperature equilibration times. If the measurement is prematurely started without the sample having been fully equilibrated, it will result in incorrect viscosity readings. To address this, ViscoQC includes the unique T-Ready^TM function, which ensures that not just the temperature device, but also the sample itself, has reached the correct temperature before measurements begin. This feature saves time by preventing unnecessary waiting or premature measurements, ensuring accurate and reliable viscosity values.

Magnetic coupling: Prevent instrument breakdowns

Viscometer failures are often caused by improper spindle attachment, which can damage the mechanics of the device. ViscoQC 300 mitigates this risk with its magnetic spindle coupling, simplifying attachment and preventing damage from incorrect installation. A special feature is the automatic spindle recognition with the unique Toolmaster^TM, minimizing the possibility of a wrongly selected spindle geometry, therefore ensuring valid and traceable measurements. You can even go one step further and limit measurement methods to a specific spindle type so that incorrect measurements are virtually impossible.

Customized automation: Save time, increase accuracy

The ability to control the entire setup via the viscometer’s display empowers the operator to easily configure their own measurement methods. Standard methods such as ASTM D4402, AASHTO T316 or DIN EN 13302 can be simulated and the entire measurement process fully automated, thereby freeing up operator time.

Users can define test parameters such as temperature, shear rate/speed, testing time and more. Additionally, users can create temperature ramps, run speed scans to determine shear thinning (non-Newtonian) behaviour, or create a sophisticated multi-step method with up to 40 steps. The ViscoQC 300 empowers users to optimize their testing processes without the need for separate temperature program synchronization, significantly simplifying their daily measurements.

The innovative TruMode^TM feature allows ViscoQC to automatically select the ideal measuring speed for your specific sample, ensuring optimal torque levels (typically between 80 % and 90 %) for maximum accuracy in every measurement.
