3P graviSorb series – Gravimetric Water Sorption Analyzers
The 3P graviSorb is a fully automated, gravimetric, multi-sample, high load capacity, high resolution, and dynamic water vapor sorption analyzer.
It measures adsorption and desorption isotherms of water vapor both accurately and sensitively, including sorption kinetics, with minimal operator involvement.
The weight of up to 12 samples is monitored and recorded as the relative humidity is automatically varied by blending dry carrier gas with a saturated gas stream.
The carousel balance design of the 3P graviSorb allows increased analysis throughput by simultaneous investigation of up to 12 different samples, or 11 + 1 if one station is running an empty sample chamber or even a reference material for direct comparison.
The 3P graviSorb is an ideal solution for the determination of water uptakes for research and quality assurance. The complete automatic measuring process together with the precise balance, broad climate range and user-friendly software make it the ideal instrument for high sample throughput with a minimum of costs and maintenance.
Characterization of powders by means of vapor sorption can verify sample behaviour with regards to polar solvents on materials. A detailed description of the method can be found here.
