Designed for advanced materials research, this system combines a precisely controlled environment—with wide-ranging vapor delivery, temperature flexibility, and compatibility with aggressive chemical conditions—to enable complex DVS experiments across a variety of challenging applications. The MSB design integrates effortlessly with automated vapor and temperature regulation, user-defined testing protocols, advanced data analysis, and comprehensive reporting, enhancing both workflow efficiency and experimental clarity.
What truly distinguishes MSB-based systems from traditional dynamic vapor sorption instruments is their contactless measurement principle—ensuring a stable, contamination-free environment for collecting high-quality data under real-world conditions.
Samples are housed within a sealed, corrosion-resistant chamber. Any change in mass is transmitted through a magnetic assembly to a high-precision microbalance operating at ambient pressure. This contact-free transfer ensures long-term stability, exceptional resolution, and minimal signal drift—even over extended experimental durations or during thermal cycling.
A standout feature of the RuboSORP MSB is its dual-sample capability. The system can simultaneously analyze two samples or substitute one with a calibrated sinker for direct gas density measurement via Archimedes’ principle. This is especially valuable in high-pressure or multi-component gas systems where conventional equations of state fall short.
