Get started immediately with a complete, ready-to-use solution for ASTM D2983 testing. The package includes ViscoQC 300 L, the PTD 175 Peltier temperature device, the 4B2 spindle, and 100 disposable cups – everything you need to start measuring right away. Fully automated workflows with precise temperature control minimize operator influence and deliver reliable low-temperature viscosity measurements for gear oils, automatic transmission fluids, hydraulic oils, and other lubricants.

Key features

Full automation from measurement to results

ViscoQC automates the complete ASTM D2983 Procedure D workflow with a preconfigured, ASTM-compliant method – no PC required. Precise temperature control from -40 °C to +90 °C and disturbance-free sample handling deliver highly repeatable results while minimizing operator influence. Start a measurement with the push of a button and let the system run unattended, saving time, reducing variability, and simplifying laboratory scheduling.

Safer, simpler Peltier cooling

Solid-state Peltier cooling eliminates the need for flammable and toxic cooling liquids, making ASTM D2983 testing safer, simpler, and more sustainable. Its compact design saves valuable bench space, while energy consumption is reduced by up to 90 %. With no cooling liquids to replace, maintenance is minimized and operating costs stay low.

Effortless handling for everyday efficiency

Magnetic spindle coupling enables quick, instrument-friendly attachment, while the cup insert and precise alignment of the viscometer head and temperature device simplify setup. Integrated digital leveling ensures correct positioning for accurate measurements and helps protect the instrument’s mechanics from premature wear.

Precise calibration, lower service costs

Built-in calibration wizards simplify in-house calibration and help ensure reliable, accurate results. Fully automated temperature calibration with the Anton Paar MKT 50 supports up to 20 templates with multiple set temperatures, while the guided spindle calibration wizard maintains measurement accuracy. Performing both calibrations in-house reduces service costs and minimizes instrument downtime.

Seamless data handling and connectivity

Every ASTM D2983 measurement report – including the final result and all related data – is stored automatically on ViscoQC. Reports can be printed directly or exported as PDF and CSV files via USB. For fully digital workflows, AP Connect enables automated, paperless transfer to LIMS and other laboratory data management systems, improving traceability and data accessibility.
