A flexible selection of dosing and blending devices provide accurate control of the composition and pressure of the reaction atmosphere. Designed and built with over 20 years of experience and field-proven by hundreds of customers, the Rubotherm Series IsoSORP SA offers the widest available pressure range of all gravimetric sorption analyzers, and represents the industry standard for application-relevant analysis.
Key Features
* German Patent no. 10 2009 009 204.8
- Non-contact sample weighing enables hermetic separation between sample cell and balance, eliminating risk of balance damage from reaction gases, pressure or temperature inside the sample cell
- Metallically sealed sample reactor cell enables measurements in corrosive, explosive, or toxic reaction gases, from cryogenic to high temperatures, and from vacuum to high pressure.
- Unique automatic sample decoupling enables taring of balance during experiments and provides unmatched long-term baseline stability for the most accurate measurements without manual balance calibrations required by competitive devices
- Entire sample cell wetted by the reaction gases can be heated, preventing condensation of reaction gas vapors such as water vapor, CO2, ammonia etc., even at high pressures or humidity
- Gravimetric measurement of the reaction gas density in the sample cell allows automatic and accurate buoyancy correction of the gravimetric data at all pressure and temperature conditions, as well as reaction gas compositions
- The large dynamic weighing range and sample volume allows measurements with representative, large and/or heavy samples
