Anton Paar has introduced the Diana 301 and 701, a new line of automated distillation analysers designed for industrial fuel and solvent applications. These systems are now commercially available to streamline testing workflows by minimizing maintenance requirements.
Why it matters
By replacing traditional cooling methods with liquid-free technology, the Diana series attempts to reduce the frequency of manual maintenance and system downtime in industrial laboratories. This shift is designed to improve throughput for facilities relying on standardized chemical distillation testing.
The Diana heating element is validated for more than 10,000 cycles, offering a high-durability threshold for industrial testing. The systems support specific compliance requirements, with the 301 meeting ASTM D86 and EN ISO 3405, while the 701 aligns with ASTM D1078 and ASTM D850.
The players
Anton Paar
An analytical instrument manufacturer specializing in physical property characterization and automated laboratory systems.
The details
The instruments utilize liquid-free Peltier cooling—a thermoelectric process that creates a heat flux between two different materials—to eliminate the need for traditional liquid-based cooling systems. To prevent interference, they incorporate anti-condensation technology and use a metal vapour temperature sensor for precision. Additionally, integrated sensor memory stores identification and calibration data to enable automatic sensor recognition, removing the need for manual data entry between test runs.

The Tech Race
The Diana series sits within a competitive landscape of automated laboratory equipment designed to adhere to long-standing industrial benchmarks like the ASTM D86 distillation standard. By embedding sensor recognition and high-cycle heating elements, the firm aims to capture market share from labs looking to modernize legacy, manually-intensive testing workflows.
Laboratory managers can expect improved instrument uptime due to the reduction of liquid-based maintenance tasks. The system's automatic sensor recognition requires compatible hardware sensors to enable the full benefit of its plug-and-play calibration features.
The takeaway
The Diana series marks an industry effort to move toward modular, self-calibrating laboratory hardware that minimizes operator intervention. Practitioners should watch for future independent validation reports to confirm whether the 10,000-cycle heater rating translates to significant operational cost savings.
