mixSorb L series
mixSorb L (formerly dynaSorb BT)
The mixSorb L series provides unique capabilities to investigate arbitrarily complex dynamic sorption processes in a uniquely safe and easy-to-use bench-top instrument. Technical adsorbents such as zeolites, active carbons, silica gels, etc. can be investigated under authentic process conditions in a broad temperature (-20 °C to 400 °C) and pressure (up to 85 bar) range, with adjustable gas flow rates up to 40 L/min and well-defined gas compositions.
The mixSorb S series provides unique capabilities to investigate novel materials, like MOFs COFs etc. by mixed gas adsorption, especially for R&D.
