Pushing the Limits of Cryogenic Tribology
Understanding friction, wear, hardness, and scratch resistance at ultra-low temperatures is critical for next-generation technologies, from superconducting materials and quantum devices to space exploration and cryogenic mechanical systems.
Conventional tribometers cannot reproduce these extreme operating conditions, while traditional cryogenic systems can be limited by helium consumption, temperature stability, and measurement constraints.
The MVT-3.5K Ultra-Low Temperature Tribometer brings controlled tribological and mechanical testing down to 3.5 K, allowing researchers to characterize materials, coatings, and interfaces under conditions approaching their actual operating environment.
Closed-Loop Helium. Zero Consumption.
Ultra-low-temperature experiments can require long cooling and testing cycles. The MVT-3.5K uses a closed-loop liquid-helium system in which helium is fully contained and continuously recirculated.
There is no helium loss and no refilling requirement, eliminating the interruptions and supply risks associated with consumable helium.
The system combines rapid, controlled cooldown from ambient conditions with stable temperature control throughout extended test cycles. This enables long-duration experiments at ultra-low temperatures while maintaining the thermal stability required for reliable tribological measurements.
Accurate Data with a Complete Thermal Profile
At ultra-low temperatures, knowing the temperature at the actual test location is critical. The MVT-3.5K continuously records temperatures throughout cooldown and steady-state operation, including the sample, stage, and cooling system.
Temperature measurements are synchronized with friction, force, and position data, providing a complete picture of both thermal and tribological behavior throughout the experiment.
Integrated software provides real-time monitoring, data visualization, thermal profiling, and tribological analysis, helping researchers correlate changes in material behavior directly with temperature.
