Process Balances
Our digital laboratory balances provide real-time data for calculating flow, membrane flux and mass balances.
Real-time analysis
The programmable balances process weight data directly during the experiment and use it to calculate relevant process parameters in real time.
Model and data analysis
Model parameters, derivatives and other process data can be calculated automatically from the continuously recorded weight data.
Mass balance
By storing and analysing weight data over time, process behaviour can be analysed and mass balances drawn up.
Principle of operation
The precision balance measures mass using an integrated load cell.
Strain gauges convert the mechanical deformation caused by the applied load
into an electrical signal. An integrated 24-bit A/D converter digitises
the signal for high-resolution measurement.
This allows even very small changes in mass to be detected reliably.
With up to 20 measurements per second, dynamic processes and continuous
material flows can be monitored in real time.
Controlled addition for diafiltration and continuous processes.
A second balance can be used to control the addition of buffer, water or other process liquids. As permeate is removed, fresh liquid can be added automatically at a defined rate or according to the measured mass change. This enables precise diafiltration, constant-volume operation and other controlled feeding strategies—while maintaining a continuous mass balance throughout the experiment.
