Classification means that particular, disturbing particles are filtered from the suspension. This can include a particle collective or specific particle sizes or specific kinds of particles. The purity is essential to the subsequent sale of the product.
BoCrossTest is a laboratory-scale dynamic crossflow filter. Like BoCross Dynamic and BoCross MicroScreen, it operates on the principle of dynamic crossflow filtration and uses the shear stress effect to prevent solid deposits on the filter medium.
With small sample quantities, BoCrossTest enables the determination of the filtration behavior under crossflow conditions. Various suspensions and filter media (polymer membranes, metal mesh, ceramic membranes) can be investigated. BoCrossTest can be operated both, discontinuously and continuously.
BoCrossTest is characterized by the following features:
- portable laboratory filter with small dimensions (e.g. for use in fume cupboards)
- only small sample volume of 1 to 40 l required (depending on test scope)
- use of different filter media
- fast change of filter media
- easy handling
BoCrossTest in action
BoCrossTest allows small sample quantities to be analyzed for filtration behavior under crossflow conditions - both for general crossflow filtration such as filtration in tubular membranes but especially for a dynamic crossflow filtration at higher shear rates and higher particle loadings.
For various suspensions and filter media (polymeric membranes, metal mesh, ceramic membranes), the possibilities of crossflow filtration can be determined regarding
BoCrossTest supplies the filtration parameters important for a filter layout, such as
- rotor speed
- range of concentration
- flow rate.
