Grade Description Application examples1,2
DL90 Very coarse primary grade on top of a coarse secondary filter for filtrations with high solid concentrations2 Primary clarification of mammalian cell cultures, insect cell cultures, microbial fermentations, vaccines
DL75 Pure cellulose pre-filter combined with a coarse secondary filter Primary clarification of mammalian cell cultures, insect cell cultures, microbial fermentations, vaccines
DL60 Coarse primary grade with a secondary fine filtration grade for lower to moderate solid concentrations Post-perfusion bioreactors, vaccines
DL20 Fine filtration grade combined with a standard bioburden reduction grade for the removal of particles Post centrifuge mammalian cell cultures, post primary depth filtration, process precipitates
DL10 Fine filtration grade followed by an very tight secondary filter for the removal of high concentrations of small particles Post centrifuge microbial (e.g. E. coli) lysates, post primary depth filtration step, process precipitates
1 The listed examples are indicative and need to be confirmed by small scale tests
