Ultra-sensitive microcalorimeter for precise thermal analysis of solids, liquids and solutions.

The CAL L92 from Linseis Calneos is an ultra-sensitive microcalorimeter designed to deliver the highest precision in thermal analysis. With its unique sensor design, direct sample temperature measurement, and Joule effect calibration, it provides unrivalled accuracy for studying solids, liquids and even highly dilute solutions.

Equipped with interchangeable measurement cells, the system covers a broad range of applications. Batch and high-pressure Cp cells allow highly accurate heat capacity determinations, while bi-compartment and continuous flow cells enable advanced studies of chemical reactions, mixing enthalpies and gas dissolution processes under pressures up to 100 bar. This flexibility makes the CAL L92 a powerful tool for both routine measurements and specialized research tasks.

The instrument operates within a temperature range from -60 °C to 170 °C, with scan rates from 0.001 to 5 °C/min and a temperature regulation precision of 100 µ°C. Its exceptional low-noise performance (0.05 μW RMS) ensures that even the weakest transitions can be detected and analyzed with confidence.

Applications include detailed heat capacity studies, melting and crystallization analysis, detection of liquid-liquid phase transitions such as demixing or degassing, and the characterization of polymers like PTFE. Thanks to its compact footprint and innovative design, the CAL L92 combines high performance with ease of use, providing researchers with a reliable and versatile calorimetric solution.

Whether you are exploring phase transitions, studying reaction enthalpies, or analyzing gas-laden solutions under pressure, the CAL L92 delivers the sensitivity and flexibility required to push the boundaries of thermal analysis.
