When in need for a compact and easy to use system for quickly evaluating fluxes of membranes or filters, the Convergence crossflow system PONTOS is the perfect choice. The system performs cross-flow and dead-end tests from 1.5 up to 60 bar. The system is flexible and can connect Convergence test cells and modules, but also third party test cells and modules.
Via the easy to use touchscreen interface the user can set up pressure step experiments. The system runs automatically and logs the data (pressures, feed flow, permeate weight and flux).The integrated feed vessel has a cooling/heating option and can also be connected to an external vessel. The automatic pressure controller can run both at low pressure and high pressures, making the system suitable for UF up to RO membrane processes.
